The anomaly can affect the tread, the sidewall, the bead or the internal carcass.<\/p>\n<p data-start=\"1254\" data-end=\"1423\">In some cases, the deformation is visible. It can then take the form of a bulge, a hernia, a flat spot or an irregular area on the tread.<\/p>\n<p data-start=\"1425\" data-end=\"1625\">However, some damage remains invisible to the naked eye. An internal rupture, a separation of components or an ovalisation can thus cause vibrations without leaving any obvious trace.<\/p>\n<p data-start=\"1627\" data-end=\"1959\">Furthermore, a deformation must not be confused with a simple balancing problem. The symptoms may appear similar, but the causes and solutions are different. Mounting, balancing, and geometry play a particularly important role in the vehicle's behaviour.<\/p>\n<p data-start=\"1961\" data-end=\"2154\">To better understand the information on your tyres, consult the guide dedicated to <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/lire-le-marquage-des-pneus-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"2063\" data-end=\"2153\">Tyre marking<\/a>.<\/p>\n<h2 data-section-id=\"14c5xgf\" data-start=\"2156\" data-end=\"2198\">2. Signs to detect a deformed tyre<\/h2>\n<p data-start=\"2200\" data-end=\"2377\">A deformed tyre can manifest itself in several ways. Some symptoms appear while driving, while others are visible when the vehicle is stationary.<\/p>\n<h3 data-section-id=\"18fgqd0\" data-start=\"2379\" data-end=\"2422\">2.1. Vibrations while driving<\/h3>\n<p data-start=\"2424\" data-end=\"2563\">First of all, a deformation can cause vibrations in the steering wheel. These often appear from a certain speed.<\/p>\n<p data-start=\"2565\" data-end=\"2799\">When the anomaly concerns a front wheel, vibrations are generally felt in the steering wheel. Conversely, if the rear wheel is affected, the jolts are more noticeable in the seat, floor, or bodywork.<\/p>\n<p data-start=\"2801\" data-end=\"2952\">The vehicle may also give the impression of bouncing. You then feel a regular rebound, as if the wheel were no longer perfectly round.<\/p>\n<p data-start=\"2954\" data-end=\"3371\">However, vibrations don't always prove the tyre is deformed. A poor <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/montage-et-stockage-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"3041\" data-end=\"3127\">Wheel balancing<\/a>, a buckled rim or worn suspension part can cause similar symptoms. Correct balancing helps to limit vibrations and premature wear of mechanical components.<\/p>\n<h3 data-section-id=\"tyrrjw\" data-start=\"3373\" data-end=\"3409\">2.2. A less precise direction<\/h3>\n<p data-start=\"3411\" data-end=\"3567\">Furthermore, a damaged tyre can alter the vehicle's handling. The steering may then feel less precise, and the car might pull slightly to one side.<\/p>\n<p data-start=\"3569\" data-end=\"3810\">Before concluding that there is a deformation, check the tyre pressure nonetheless. Incorrect <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/pression-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"3663\" data-end=\"3742\">Tyre pressure<\/a> or a geometric defect may also explain this behaviour.<\/p>\n<p data-start=\"3812\" data-end=\"3991\">Similarly, a misaligned steering wheel or a car that consistently pulls to the right or left can indicate incorrect wheel alignment.<\/p>\n<h3 data-section-id=\"e49f34\" data-start=\"3993\" data-end=\"4024\">2.3. Unusual noises<\/h3>\n<p data-start=\"4026\" data-end=\"4182\">Furthermore, be mindful of noises that change with speed. A regular tapping, humming, or droning sound could indicate a fault.<\/p>\n<p data-start=\"4184\" data-end=\"4306\">These noises are sometimes easier to hear on a smooth road. Conversely, worn tarmac can mask them.<\/p>\n<p data-start=\"4308\" data-end=\"4477\">A cyclical noise can come from a deformed tyre. However, uneven wear, a worn bearing, or poor balancing can produce a comparable noise.<\/p>\n<h3 data-section-id=\"eb54gk\" data-start=\"4479\" data-end=\"4524\">2.4. A lump or a hernia on the flank<\/h3>\n<p data-start=\"4526\" data-end=\"4659\">When stationary, carefully examine the sidewalls of each tyre. A localised bulge or hernia is an important warning sign.<\/p>\n<p data-start=\"4661\" data-end=\"4832\">This deformation can appear after a knock against a pavement, a kerb or a pothole. It often indicates that the internal structure of the tyre has been weakened.<\/p>\n<p data-start=\"4834\" data-end=\"5062\">In this case, avoid continuing to drive. The tyre must be checked by a professional as soon as possible. You can look for a <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/montage-pneu\/?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"4970\" data-end=\"5041\">tyre fitting centre<\/a> near you.<\/p>\n<h3 data-section-id=\"ewvplg\" data-start=\"5064\" data-end=\"5106\">2.5. A dish on the tread<\/h3>\n<p data-start=\"5108\" data-end=\"5257\">A vehicle that has been stationary for a long period can develop a slight flat spot. The weight of the vehicle then rests on the same area of the tyre.<\/p>\n<p data-start=\"5259\" data-end=\"5413\">This phenomenon usually causes vibrations during the first few kilometres. In some cases, the tyre gradually regains its shape as it is driven.<\/p>\n<p data-start=\"5415\" data-end=\"5581\">However, if the vibrations persist after several kilometres, have the tyre checked. The flat spot may be permanent or hiding another problem.<\/p>\n<h3 data-section-id=\"qqo6cw\" data-start=\"5583\" data-end=\"5613\">2.6. Uneven wear<\/h3>\n<p data-start=\"5615\" data-end=\"5776\">Finally, examine the entire tread. Smoother areas, flat spots, steps or a sawtooth wear pattern can indicate an anomaly.<\/p>\n<p data-start=\"5778\" data-end=\"5953\">This <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/rodage-et-usure-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"5784\" data-end=\"5860\">Tyre wear<\/a> can originate from unsuitable pressure, worn shock absorbers or poor alignment.<\/p>\n<p data-start=\"5955\" data-end=\"6122\">More pronounced wear on one edge can also indicate a lack of parallelism. Conversely, wear in the centre is often associated with excessively high pressure.<\/p>\n<\/section>\n<section id=\"risques\"><a href=\"https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2.png\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-584 size-full\" src=\"https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2.png\" alt=\"\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2.png 1536w, https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2-300x200.png 300w, https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2-1024x683.png 1024w, https:\/\/www.pneus-online.fr\/mag\/wp-content\/uploads\/2026\/02\/pneu-deforme-2-768x512.png 768w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/a><\/section>\n<section id=\"diagnostic\">\n<h2><\/h2>\n<h2 data-section-id=\"1s6fn3u\" data-start=\"6124\" data-end=\"6147\">3. Common causes<\/h2>\n<p data-start=\"6149\" data-end=\"6287\">Tyre deformation can have several origins. Some causes are sudden, while others appear gradually.<\/p>\n<h3 data-section-id=\"xgxloj\" data-start=\"6289\" data-end=\"6324\">3.1. A collision with an obstacle<\/h3>\n<p data-start=\"6326\" data-end=\"6434\">Hitting a pothole, kerb or speed bump too quickly can damage the tyre carcass.<\/p>\n<p data-start=\"6436\" data-end=\"6599\">Even in the absence of a visible break, internal reinforcements can be weakened. A dent may then appear immediately or a few days after the impact.<\/p>\n<p data-start=\"6601\" data-end=\"6821\">After a significant impact, inspect the tyre, but also the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/jantes.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"6667\" data-end=\"6725\">Rims and wheels<\/a>. A buckled wheel can cause vibrations and give the impression that the tyre is distorted.<\/p>\n<h3 data-section-id=\"1ofhu8j\" data-start=\"6823\" data-end=\"6857\">3.2. Insufficient pressure<\/h3>\n<p data-start=\"6859\" data-end=\"7022\">Under-inflation increases the deformation of the tyre on contact with the road. Consequently, the carcass works harder and the tyre heats up more quickly.<\/p>\n<p data-start=\"7024\" data-end=\"7137\">In the long term, excessively low pressure can accelerate wear, increase consumption and weaken the sidewalls.<\/p>\n<p data-start=\"7139\" data-end=\"7490\">It is therefore important to regularly check the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/pression-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"7190\" data-end=\"7274\">Tyre inflation pressure<\/a>. Checking should be carried out when the engine is cold, in accordance with the manufacturer's recommendations. Correct pressure, in particular, helps to limit overheating and maintain grip.<\/p>\n<p data-start=\"7492\" data-end=\"7639\">When the vehicle is equipped with it, the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/tpms-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"7530\" data-end=\"7592\">TPMS system<\/a> can also signal a loss of pressure.<\/p>\n<h3 data-section-id=\"1buitdk\" data-start=\"7641\" data-end=\"7676\">3.3. An excessive load<\/h3>\n<p data-start=\"7678\" data-end=\"7820\">Each tyre has a maximum load it can support. When this limit is exceeded, the carcass is subjected to excessive stress.<\/p>\n<p data-start=\"7822\" data-end=\"7948\">The tyre can then sag, overheat and wear out more quickly. Furthermore, the vehicle's handling becomes less stable.<\/p>\n<p data-start=\"7950\" data-end=\"8225\">Before a busy departure, check the\u2019<a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/indices-charge-et-vitesse-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"7990\" data-end=\"8085\">tyre load index<\/a>. Also, comply with the manufacturer's recommendations regarding pressure when the vehicle is carrying passengers or luggage.<\/p>\n<p data-start=\"8227\" data-end=\"8390\">The load and speed indices are defined to help choose a tyre suitable for the vehicle's characteristics.<\/p>\n<h3 data-section-id=\"d6lvaq\" data-start=\"8392\" data-end=\"8429\">3.4. Prolonged Immobilisation<\/h3>\n<p data-start=\"8431\" data-end=\"8544\">When a vehicle remains parked for several weeks, its weight still rests on the same parts of the tyres.<\/p>\n<p data-start=\"8546\" data-end=\"8695\">Dishes can then appear. This phenomenon is often more pronounced when the tyres are underinflated or when temperatures are low.<\/p>\n<p data-start=\"8697\" data-end=\"8856\">To limit this risk, move the vehicle regularly when possible. Also, check the tyre pressure before a long period of inactivity.<\/p>\n<h3 data-section-id=\"17w15ka\" data-start=\"8858\" data-end=\"8887\">3.5. An assembly defect<\/h3>\n<p data-start=\"8889\" data-end=\"9040\">A tyre that is not correctly seated on the rim can rotate unevenly. The mounting line near the rim's edge will then be irregular.<\/p>\n<p data-start=\"9042\" data-end=\"9149\">Similarly, poor balancing can cause vibrations from the first few kilometres after fitting.<\/p>\n<p data-start=\"9151\" data-end=\"9437\">The <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/montage-et-stockage-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"9154\" data-end=\"9236\">tyre fitting<\/a> It should therefore be entrusted to a trained and properly equipped professional. The direction of rotation, the position of the tyre and the balancing must be respected in particular.<\/p>\n<h3 data-section-id=\"1v7t689\" data-start=\"9439\" data-end=\"9478\">3.6. A buckled or damaged rim<\/h3>\n<p data-start=\"9480\" data-end=\"9602\">A rim can become deformed after a significant impact. In this case, the wheel no longer rotates perfectly smoothly.<\/p>\n<p data-start=\"9604\" data-end=\"9693\">The driver may then feel vibrations comparable to those of a deformed tyre.<\/p>\n<p data-start=\"9695\" data-end=\"9863\">Sometimes the rim is the only damaged part. However, the impact may also have weakened the tyre. A thorough inspection of the wheel is therefore essential.<\/p>\n<h3 data-section-id=\"cyusgp\" data-start=\"9865\" data-end=\"9899\">3.7. Tyre ageing<\/h3>\n<p data-start=\"9901\" data-end=\"10052\">Over time, rubber gradually loses its flexibility. Cracks or splits may then appear on the sidewall and between the grooves.<\/p>\n<p data-start=\"10054\" data-end=\"10137\">The tyre also becomes more sensitive to shocks and temperature variations.<\/p>\n<p data-start=\"10139\" data-end=\"10308\">However, age is not the only criterion to consider. Mileage, overall condition, storage conditions, and maintenance also play an important role.<\/p>\n<h2 data-section-id=\"b4izbw\" data-start=\"10310\" data-end=\"10334\">4. Risks and dangers<\/h2>\n<p data-start=\"10336\" data-end=\"10498\">Continuing to drive with a deformed tyre can affect the vehicle's handling. The level of risk, however, depends on the nature and severity of the damage.<\/p>\n<h3 data-section-id=\"o3hfgt\" data-start=\"10500\" data-end=\"10530\">4.1. Loss of grip<\/h3>\n<p data-start=\"10532\" data-end=\"10711\">First, contact between the tyre and the road surface becomes less consistent. Grip can then decrease during braking, cornering or when performing an emergency manoeuvre.<\/p>\n<p data-start=\"10713\" data-end=\"10934\">On a wet road, this loss of stability can be even more noticeable. The condition of the tyre and the weather conditions directly influence the available grip level.<\/p>\n<p data-start=\"10936\" data-end=\"11084\">To better understand these phenomena, consult the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/guide-de-l-adherence-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"10987\" data-end=\"11083\">Tyre grip guide<\/a>.<\/p>\n<h3 data-section-id=\"176j0w9\" data-start=\"11086\" data-end=\"11114\">4.2. Accelerated wear<\/h3>\n<p data-start=\"11116\" data-end=\"11255\">Next, the tread wears out unevenly. Some areas bear more stress and deteriorate faster.<\/p>\n<p data-start=\"11257\" data-end=\"11403\">Consequently, the tyre's lifespan decreases. Uneven wear can also make the vehicle noisier and less comfortable.<\/p>\n<h3 data-section-id=\"anyoat\" data-start=\"11405\" data-end=\"11441\">4.3. Persistent vibrations<\/h3>\n<p data-start=\"11443\" data-end=\"11563\">Furthermore, vibrations can stress the bearings, shock absorbers, steering, and suspension components.<\/p>\n<p data-start=\"11565\" data-end=\"11791\">Even though they may seem minor, they should not be ignored. Incorrect balancing can, in particular, lead to premature wear of tyres and certain mechanical components.<\/p>\n<h3 data-section-id=\"10ka2vv\" data-start=\"11793\" data-end=\"11830\">4.4. Higher consumption<\/h3>\n<p data-start=\"11832\" data-end=\"11974\">A deformed or under-inflated tyre increases rolling resistance. The engine then has to exert more effort to maintain speed.<\/p>\n<p data-start=\"11976\" data-end=\"12091\">Fuel consumption may therefore increase. Furthermore, the vehicle loses in terms of comfort and handling precision.<\/p>\n<h3 data-section-id=\"1921kx\" data-start=\"12093\" data-end=\"12134\">4.5. A risk of tyre failure<\/h3>\n<p data-start=\"12136\" data-end=\"12242\">Finally, a hernia, delamination or internal deterioration can severely weaken the tyre.<\/p>\n<p data-start=\"12244\" data-end=\"12383\">The risk increases with speed, load and heating. Therefore, a visible bulge on the sidewall should never be taken lightly.<\/p>\n<p data-start=\"12385\" data-end=\"12550\">If you experience strong vibrations or a bump in a tyre, slow down gradually. Then, stop in a safe location and request a professional inspection.<\/p>\n<h2 data-section-id=\"u4n0b3\" data-start=\"12552\" data-end=\"12603\">5. Diagnosis: how to check step by step<\/h2>\n<p data-start=\"12605\" data-end=\"12696\">You can perform several simple checks before going to a garage.<\/p>\n<h3 data-section-id=\"11xtljh\" data-start=\"12698\" data-end=\"12749\">5.1. Step 1: Visually inspect the tyres<\/h3>\n<p data-start=\"12751\" data-end=\"12857\">Begin by parking the vehicle on a level surface. Apply the handbrake, then turn off the engine.<\/p>\n<p data-start=\"12859\" data-end=\"12912\">Next, examine each flank. Specifically look for:<\/p>\n<ul data-start=\"12914\" data-end=\"13037\">\n<li data-section-id=\"10u2gw5\" data-start=\"12914\" data-end=\"12927\">a lump ;<\/li>\n<li data-section-id=\"1cazmxc\" data-start=\"12928\" data-end=\"12942\">a hernia ;<\/li>\n<li data-section-id=\"1txemee\" data-start=\"12943\" data-end=\"12958\">a cut ;<\/li>\n<li data-section-id=\"x8ecjk\" data-start=\"12959\" data-end=\"12974\">a crack ;<\/li>\n<li data-section-id=\"1lhwn14\" data-start=\"12975\" data-end=\"13007\">an unusually bulging area; ;<\/li>\n<li data-section-id=\"oixuzu\" data-start=\"13008\" data-end=\"13037\">gum recession.<\/li>\n<\/ul>\n<p data-start=\"13039\" data-end=\"13222\">Also observe the tread. Its <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/rodage-et-usure-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"13085\" data-end=\"13160\">wear level<\/a> it should remain as regular as possible across the entire width.<\/p>\n<p data-start=\"13224\" data-end=\"13332\">Finally, look at the line situated near the edge of the rim. It should remain regular all the way around the wheel.<\/p>\n<h3 data-section-id=\"y6dh7z\" data-start=\"13334\" data-end=\"13387\">5.2. Step 2: Checking pressure and load<\/h3>\n<p data-start=\"13389\" data-end=\"13518\">Measure the pressure when the tyres are cold. The vehicle should not have completed a long journey just before checking.<\/p>\n<p data-start=\"13520\" data-end=\"13706\">Next, compare the value obtained with the manufacturer's recommendations. These are usually found in the vehicle's manual, on the door or near the fuel filler flap.<\/p>\n<p data-start=\"13708\" data-end=\"13936\">Also, take the opportunity to check that the vehicle is not overloaded. Always respect the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/indices-charge-et-vitesse-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"13804\" data-end=\"13906\">load and speed indices<\/a> indicated for your vehicle.<\/p>\n<h3 data-section-id=\"1ekw8d6\" data-start=\"13938\" data-end=\"14005\">5.3. Step 3: identify when vibrations appear<\/h3>\n<p data-start=\"14007\" data-end=\"14097\">During a careful journey, note the conditions under which the problem manifests itself:<\/p>\n<ul data-start=\"14099\" data-end=\"14442\">\n<li data-section-id=\"p9iscr\" data-start=\"14099\" data-end=\"14156\">Do vibrations start at a specific speed?<\/li>\n<li data-section-id=\"oiq0bu\" data-start=\"14157\" data-end=\"14198\">Are they present from the start?<\/li>\n<li data-section-id=\"419yng\" data-start=\"14199\" data-end=\"14254\">Are they felt in the steering wheel or the seat?<\/li>\n<li data-section-id=\"1kcpv38\" data-start=\"14255\" data-end=\"14297\">Does the noise increase with speed?<\/li>\n<li data-section-id=\"urx9go\" data-start=\"14298\" data-end=\"14333\">Does the vehicle pull to one side?<\/li>\n<li data-section-id=\"1a44ewk\" data-start=\"14334\" data-end=\"14377\">Did the problem occur after an impact?<\/li>\n<li data-section-id=\"140fb0r\" data-start=\"14378\" data-end=\"14442\">Do the vibrations disappear after a few kilometres?<\/li>\n<\/ul>\n<p data-start=\"14444\" data-end=\"14513\">These details will help the professional to guide their diagnosis.<\/p>\n<h3 data-section-id=\"1vlhq1y\" data-start=\"14515\" data-end=\"14584\">5.4. Step 4: Differentiate deformation, balancing and geometry.<\/h3>\n<p data-start=\"14586\" data-end=\"14675\">An imbalance often causes vibrations within a specific speed range.<\/p>\n<p data-start=\"14677\" data-end=\"14789\">Conversely, a deformation can produce a regular bounce, a cyclic noise, or a feeling of an oval wheel.<\/p>\n<p data-start=\"14791\" data-end=\"14985\">A geometry fault tends to cause abnormal wear on one edge of the tyre. The vehicle may also pull to one side or have a misaligned steering wheel.<\/p>\n<p data-start=\"14987\" data-end=\"15116\">However, these symptoms can combine, making it difficult to establish a reliable diagnosis without professional equipment.<\/p>\n<h3 data-section-id=\"1a4c3nf\" data-start=\"15118\" data-end=\"15171\">5.5. Step 5: Get the wheel checked at the workshop<\/h3>\n<p data-start=\"15173\" data-end=\"15299\">Finally, go to a garage or a fitting centre. The professional will be able to spin the wheel on a balancing machine.<\/p>\n<p data-start=\"15301\" data-end=\"15325\">He will check, among other things:<\/p>\n<ul data-start=\"15327\" data-end=\"15535\">\n<li data-section-id=\"1bnxgwl\" data-start=\"15327\" data-end=\"15355\">wheel balancing ;<\/li>\n<li data-section-id=\"1qwm3ey\" data-start=\"15356\" data-end=\"15381\">tyre ovalisation ;<\/li>\n<li data-section-id=\"qxe3ul\" data-start=\"15382\" data-end=\"15408\">the rim veil ;<\/li>\n<li data-section-id=\"lbajxk\" data-start=\"15409\" data-end=\"15451\">tyre seat on the rim ;<\/li>\n<li data-section-id=\"vfyhqt\" data-start=\"15452\" data-end=\"15477\">the condition of the carcass; ;<\/li>\n<li data-section-id=\"1utdh7l\" data-start=\"15478\" data-end=\"15505\">the condition of the shock absorbers ;<\/li>\n<li data-section-id=\"1yvxzb3\" data-start=\"15506\" data-end=\"15535\">wheel alignment.<\/li>\n<\/ul>\n<p data-start=\"15537\" data-end=\"15817\">You can find a professional through the network of <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/montage-pneu\/?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"15593\" data-end=\"15681\">Pneus Online partner fitting centres<\/a>. Pneus Online offers a network of partner garages for tyre delivery and fitting.<\/p>\n<h2 data-section-id=\"1lv9zmg\" data-start=\"15819\" data-end=\"15865\">6. Solutions: what to do and when to replace<\/h2>\n<p data-start=\"15867\" data-end=\"15927\">The solution depends on the type of deformation and its origin.<\/p>\n<h3 data-section-id=\"clbzx\" data-start=\"15929\" data-end=\"15963\">6.1. In case of a temporary flat tyre<\/h3>\n<p data-start=\"15965\" data-end=\"16048\">After prolonged immobilisation, a slight flat spot can gradually disappear.<\/p>\n<p data-start=\"16050\" data-end=\"16142\">Drive a few kilometres at a moderate speed. Then, check if the vibrations lessen.<\/p>\n<p data-start=\"16144\" data-end=\"16251\">However, stop if the shaking is significant. If it persists, have the wheels checked.<\/p>\n<h3 data-section-id=\"1dnvy7g\" data-start=\"16253\" data-end=\"16303\">6.2. In case of a lump or hernia on the flank<\/h3>\n<p data-start=\"16305\" data-end=\"16399\">A bulge on the sidewall generally indicates a weakening of the internal structure of the tyre.<\/p>\n<p data-start=\"16401\" data-end=\"16516\">In this situation, the tyre must be checked without delay. Replacement is most often necessary.<\/p>\n<p data-start=\"16518\" data-end=\"16624\">Don't try to fix the dent. Likewise, don't keep riding just to \u00abfinish the season\u00bb.<\/p>\n<h3 data-section-id=\"1yutm88\" data-start=\"16626\" data-end=\"16661\">6.3. In the event of uneven wear<\/h3>\n<p data-start=\"16663\" data-end=\"16753\">Facet wear can be caused by the shock absorbers, the balancing, or the geometry.<\/p>\n<p data-start=\"16755\" data-end=\"16874\">Therefore, we must first investigate the cause of the problem. Otherwise, the new tyre risks wearing out in the same way.<\/p>\n<p data-start=\"16876\" data-end=\"17024\">Next, the professional will determine if the tyre can still be used. When the wear is too significant, its replacement becomes necessary.<\/p>\n<h3 data-section-id=\"1c18ti3\" data-start=\"17026\" data-end=\"17057\">6.4. In case of a buckled rim<\/h3>\n<p data-start=\"17059\" data-end=\"17177\">A slightly buckled wheel can sometimes be repaired by a specialist. In other cases, it needs to be replaced.<\/p>\n<p data-start=\"17179\" data-end=\"17303\">However, the tyre must also be inspected. Indeed, the impact that caused the damage may have compromised its structure.<\/p>\n<p data-start=\"17305\" data-end=\"17406\">After the wheel rim has been repaired or replaced, it will require rebalancing.<\/p>\n<h3 data-section-id=\"1avluch\" data-start=\"17408\" data-end=\"17445\">6.5. In the event of faulty installation<\/h3>\n<p data-start=\"17447\" data-end=\"17546\">When the tyre is incorrectly positioned on the rim, a professional can sometimes correct the fitting.<\/p>\n<p data-start=\"17548\" data-end=\"17616\">The wheel must then be dismantled, inspected, reassembled and balanced.<\/p>\n<p data-start=\"17618\" data-end=\"17712\">However, this repair is only possible if the tyre has not sustained any structural damage.<\/p>\n<h3 data-section-id=\"68olg8\" data-start=\"17714\" data-end=\"17767\">6.6. When must the tyre be replaced?<\/h3>\n<p data-start=\"17769\" data-end=\"17834\">Replacement becomes indispensable in several situations:<\/p>\n<ul data-start=\"17836\" data-end=\"18192\">\n<li data-section-id=\"18bb6ni\" data-start=\"17836\" data-end=\"17885\">a lump or hernia appears on the flank; ;<\/li>\n<li data-section-id=\"1ubkh96\" data-start=\"17886\" data-end=\"17924\">the rubber is peeling away from the carcass ;<\/li>\n<li data-section-id=\"8ja0n5\" data-start=\"17925\" data-end=\"17961\">a deep cut is visible; ;<\/li>\n<li data-section-id=\"tfqc1q\" data-start=\"17962\" data-end=\"18004\">The internal structure appears to be damaged. ;<\/li>\n<li data-section-id=\"1mq4j7d\" data-start=\"18005\" data-end=\"18058\">The deformation is confirmed on a wheel balancer. ;<\/li>\n<li data-section-id=\"107wlra\" data-start=\"18059\" data-end=\"18118\">The vibrations persist despite correct balancing. ;<\/li>\n<li data-section-id=\"1htsc4n\" data-start=\"18119\" data-end=\"18153\">The tyre sustained a violent shock. ;<\/li>\n<li data-section-id=\"1ravw4o\" data-start=\"18154\" data-end=\"18192\">the wear has reached a dangerous level.<\/li>\n<\/ul>\n<p data-start=\"18194\" data-end=\"18339\">Before your purchase, consult the recommendations for <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/bien-changer-ses-pneus-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"18248\" data-end=\"18338\">changing your tyres<\/a>.<\/p>\n<p data-start=\"18341\" data-end=\"18497\">Check also the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/top-dimension-pneu-auto.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"18364\" data-end=\"18447\">Your tyre dimensions<\/a>, their load index and their speed rating.<\/p>\n<p data-start=\"18499\" data-end=\"18775\">You can then search for <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/pneus-auto.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"18534\" data-end=\"18616\">car tyres suitable for your vehicle<\/a>. Pneus Online notably allows you to select tyres based on their dimensions, season, and manufacturer.<\/p>\n<p data-start=\"18777\" data-end=\"18975\">When two tyres need replacing, also check the condition of the two tyres on the same axle. Always follow the fitting rules and the manufacturer's recommendations.<\/p>\n<h2 data-section-id=\"11lyk2\" data-start=\"18977\" data-end=\"19017\">7. Prevention: avoiding deformation<\/h2>\n<p data-start=\"19019\" data-end=\"19093\">A few simple habits help reduce the risk of deformation.<\/p>\n<h3 data-section-id=\"1oin7s8\" data-start=\"19095\" data-end=\"19139\">7.1. Check the pressure regularly<\/h3>\n<p data-start=\"19141\" data-end=\"19273\">Check the tyre pressure about once a month. Also carry out this check before a long journey or when the vehicle is heavily laden.<\/p>\n<p data-start=\"19275\" data-end=\"19403\">Always use the manufacturer's recommended values. Furthermore, measure the pressure when the tyres are cold.<\/p>\n<p data-start=\"19405\" data-end=\"19544\">Appropriate pressure helps to limit overheating, irregular wear, and loss of grip.<\/p>\n<h3 data-section-id=\"fc17ug\" data-start=\"19546\" data-end=\"19571\">7.2. Avoiding shocks<\/h3>\n<p data-start=\"19573\" data-end=\"19652\">Slow down when approaching a pothole, kerb, or speed bump.<\/p>\n<p data-start=\"19654\" data-end=\"19736\">A shock, even at moderate speed, can weaken the carcass or deform the rim.<\/p>\n<p data-start=\"19738\" data-end=\"19875\">After a significant impact, quickly inspect the wheel. Also remain attentive to the appearance of unusual vibrations or noises.<\/p>\n<h3 data-section-id=\"1n8z2bg\" data-start=\"19877\" data-end=\"19914\">7.3. Respect the maximum load<\/h3>\n<p data-start=\"19916\" data-end=\"19991\">Do not exceed the intended capabilities of the vehicle and tyres.<\/p>\n<p data-start=\"19993\" data-end=\"20132\">Before going on holiday, distribute luggage evenly. Also adjust tyre pressure if recommended by the manufacturer.<\/p>\n<p data-start=\"20134\" data-end=\"20321\">Finally, check the information on the sidewall using the dedicated guide for the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/lire-le-marquage-des-pneus-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"20219\" data-end=\"20320\">Reading tyre markings<\/a>.<\/p>\n<h3 data-section-id=\"12mz5d3\" data-start=\"20323\" data-end=\"20360\">7.4. Have balancing checked<\/h3>\n<p data-start=\"20362\" data-end=\"20435\">A balancing must be performed when fitting a tyre to a wheel rim.<\/p>\n<p data-start=\"20437\" data-end=\"20530\">Furthermore, book an appointment if any vibrations appear after a tyre change.<\/p>\n<p data-start=\"20532\" data-end=\"20696\">Balancing concerns both the front and rear wheels. It helps to limit vibrations and premature wear.<\/p>\n<h3 data-section-id=\"1r1ykb8\" data-start=\"20698\" data-end=\"20735\">7.5. Have the alignment checked<\/h3>\n<p data-start=\"20737\" data-end=\"20799\">Poor geometry often leads to uneven wear.<\/p>\n<p data-start=\"20801\" data-end=\"20917\">Get it checked if the vehicle pulls to one side, after an impact, or if the tyres are wearing quickly on one edge.<\/p>\n<p data-start=\"20919\" data-end=\"21080\">Correct geometry also helps to improve road-holding and extend tyre life.<\/p>\n<h3 data-section-id=\"9cdc9q\" data-start=\"21082\" data-end=\"21121\">7.6. Storing tyres correctly<\/h3>\n<p data-start=\"21123\" data-end=\"21212\">Finally, store the removed tyres in a dry, cool, and dark place.<\/p>\n<p data-start=\"21214\" data-end=\"21313\">Keep them away from heat sources, chemicals, and ozone-producing appliances.<\/p>\n<p data-start=\"21315\" data-end=\"21540\">Before storing, clean the tyres and remove any stones from the grooves. Pneus Online particularly recommends storing them in a cool, dry place protected from the sun.<\/p>\n<p data-start=\"21542\" data-end=\"21706\">Find all the useful precautions in the guide dedicated to <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/montage-et-stockage-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"21608\" data-end=\"21705\">Tyre fitting and storage<\/a>.<\/p>\n<h2 data-section-id=\"15rsx5x\" data-start=\"21708\" data-end=\"21717\">8. FAQ<\/h2>\n<h3 data-section-id=\"1t13kmp\" data-start=\"21719\" data-end=\"21791\">8.1. What are the most common symptoms of a deformed tyre?<\/h3>\n<p data-start=\"21793\" data-end=\"21893\">The most frequent signs are vibrations, cyclic noises, and bouncing sensations.<\/p>\n<p data-start=\"21895\" data-end=\"21971\">Uneven wear, a bulge or a hernia may also appear.<\/p>\n<p data-start=\"21973\" data-end=\"22074\">However, these symptoms can have other causes. An inspection at a workshop is therefore still recommended.<\/p>\n<h3 data-section-id=\"1p93v66\" data-start=\"22076\" data-end=\"22134\">8.2. Is it dangerous to drive with a deformed tyre?<\/h3>\n<p data-start=\"22136\" data-end=\"22197\">Yes, especially when the carcass or the flank is damaged.<\/p>\n<p data-start=\"22199\" data-end=\"22277\">The tyre can lose stability and become more vulnerable to failure.<\/p>\n<p data-start=\"22279\" data-end=\"22388\">In case of a visible hernia or bulge, do not continue your journey. Have the tyre checked quickly.<\/p>\n<h3 data-section-id=\"125izfq\" data-start=\"22390\" data-end=\"22462\">8.3. How to differentiate a deformed tyre from poor balancing?<\/h3>\n<p data-start=\"22464\" data-end=\"22553\">An imbalance often causes vibrations within a specific speed range.<\/p>\n<p data-start=\"22555\" data-end=\"22667\">Conversely, a deformation can produce a regular bounce, a cyclic noise, or a feeling of an oval wheel.<\/p>\n<p data-start=\"22669\" data-end=\"22760\">However, only a check on a wheel balancer can confirm the origin of the problem.<\/p>\n<h3 data-section-id=\"ad3bx2\" data-start=\"22762\" data-end=\"22808\">8.4. Can a deformed tyre be repaired?<\/h3>\n<p data-start=\"22810\" data-end=\"22961\">A structural deformation generally does not repair itself. This is particularly the case with a hernia, an internal rupture, or a detached callus.<\/p>\n<p data-start=\"22963\" data-end=\"23076\">Conversely, a mounting, balancing or rim problem can sometimes be corrected if the tyre remains intact.<\/p>\n<h3 data-section-id=\"1kb4c51\" data-start=\"23078\" data-end=\"23131\">8.5. What to do after hitting a pothole?<\/h3>\n<p data-start=\"23133\" data-end=\"23178\">After the shock, inspect the tyre and the wheel rim.<\/p>\n<p data-start=\"23180\" data-end=\"23304\">Also check the pressure and remain attentive to vibrations, noises or changes in the vehicle's behaviour.<\/p>\n<p data-start=\"23306\" data-end=\"23426\">If a bulge, cut, or crack appears, do not continue your journey. Get the wheel checked without delay.<\/p>\n<h3 data-section-id=\"1ldpa1y\" data-start=\"23428\" data-end=\"23483\">8.6. Is it possible to drive with a slightly oval tyre?<\/h3>\n<p data-start=\"23485\" data-end=\"23541\">It is best to seek professional advice.<\/p>\n<p data-start=\"23543\" data-end=\"23631\">Even slight ovalisation can cause vibrations and accelerate tyre wear.<\/p>\n<p data-start=\"23633\" data-end=\"23715\">Furthermore, its origin must be identified before normal operation can resume.<\/p>\n<h3 data-section-id=\"zlfvf3\" data-start=\"23717\" data-end=\"23786\">8.7. Can a pressure drop cause deformation?<\/h3>\n<p data-start=\"23788\" data-end=\"23878\">Yes. Insufficient pressure accentuates tyre flattening and increases its heating.<\/p>\n<p data-start=\"23880\" data-end=\"23974\">In the long term, under-inflation can weaken the casing and promote irregular wear.<\/p>\n<p data-start=\"23976\" data-end=\"24084\">Check regularly the <a class=\"decorated-link\" href=\"https:\/\/www.pneus-online.fr\/pression-conseils.html?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"24008\" data-end=\"24083\">your tyre pressure<\/a>.<\/p>\n<h3 data-section-id=\"1w3hhne\" data-start=\"24086\" data-end=\"24131\">8.8.
