To improve the roadholding, handling, and performance of your vehicle, we recommend that you mount four identical or similar tyres. If your tyres are not identical, one of the axles may not respond as rapidly or in the same way as the other, which would make it difficult to control all parts of the vehicle.
If your tyres are only minimally worn (the main tread pattern still has maximal groove depth) but you need to change a flat tyre or one damaged by an accident, it is very important that the replacement be the same type of tyre. The new tyre must be the same brand and have the same specifications as the first. It must also have the same speed/load indexes, the same profile/construction, and, of course, the same dimensions.
If two tyres have a maximal degree of wear or are damaged, you must replace them with identical or similar tyres. It is very important that you select tyres having the same characteristics as those already mounted on your vehicle.
It is a good idea to mount new tyres (or those with the least wear) in back instead of in front. The driver has little or no control over loss of rear wheel grip. By mounting new tyres in the back, grip is balanced between the two axles, which improves safety. Despite weak grip, the driver controls the front axle with the steering wheel, while the rear axle grip is optimised by the new tyres.
When two new tyres are mounted on your vehicle, don't hesitate to ask your mechanic why the tyres on one axle wore faster than those on the other. This could be due to bad alignment or incorrect geometry (click here for more details).
At PNEUS-ONLINE, we advise against waiting until your tyres reach their wear limit. Rain will increase the chances of aquaplaning starting at 0.07 inches or at 0.11 inches for wider tyres.
If all four tyres become worn at the same time, you have more flexibility in the selection of new tyres. If you are satisfied with your old tyres, you can purchase the same kind. Or if you wish to change to another profile or brand, you will obviously need to be sure that these tyres suit your vehicle. You can then select tyres that are more comfortable and offer better performance and higher endurance. Choose according to your driving style and the characteristics you are looking for, and always follow the recommendations of your vehicle manufacturer, including homologation guidelines.
Once you know how many tyres to change, you must determine the size and type of tyres you are looking for.
If you feel that the best tyre for your vehicle is too expensive compared to another brand, don't forget that tyre price is a function of other criteria such as tread wear, performance, comfort, quality, etc. How much will you save per mile with less expensive tyres?
If you plan to travel 20,000 miles with tyres that cost 7£ more than the tyre best suited to your vehicle, you might be surprised to learn that price difference per mile is 0.00015£. Does this difference justify buying a tyre that is perhaps less suitable?
