When changing tires, we often look at the brand, the size and the tread pattern of the tire. The tire valve<\/strong> It deserves your attention too. This small component contributes to the tire\u2019s tightness: a good-quality tire can lose air if its valve becomes defective.<\/p>\n

When it comes to changing to winter tires, here are the points to discuss with your mechanic so you don't forget this discreet detail.<\/p>\n

\"Checking
Pressure monitoring allows detecting a loss of air that warrants a diagnosis.<\/figcaption><\/figure>\n

What is the purpose of a tire valve?<\/h2>\n

The valve allows the inflator to be connected, the pressure to be controlled and the air to be retained once the operation is complete. Its internal mechanism and seals ensure this closure. The cap protects the entire unit from moisture and dirt; therefore, it should not be considered a mere decorative accessory.<\/p>\n

If you notice that a cap is missing, replace it with a suitable model. However, a new cap does not eliminate the need to investigate the cause of the pressure loss.<\/p>\n

When should the tire valve be changed?<\/h2>\n

Rubber ages, even when the car is driven little. A valve can thus lose its seal before the tread wears out. For a conventional rubber valve, fitting a new tire is an opportunity to replace it.<\/p>\n

It is also necessary to have it checked if a tire is regularly deflating. However, the valve is only one possible cause: a perforation or a seal failure between the tire and the rim could also be at fault.<\/p>\n

With a TPMS sensor, do I need to replace everything?<\/h2>\n

A valve associated with a pressure sensor requires an intervention adapted to its model. Replacing the tire does not necessarily require the replacement of the complete sensor.<\/strong> According to the design, the valve can be separated from the housing or some wear parts can be replaced.<\/p>\n

Maintenance kits can include, among other things, a seal, a nut, a screw, a cap or a valve. Their contents vary: the professional must choose compatible parts and follow the manufacturer\u2019s instructions, particularly the tightening torque values. Single-use components must not be reassembled.<\/p>\n

After the intervention, the checks and possible system reset follow the instructions of the vehicle manufacturer. A light that turns on therefore deserves a check.<\/p>\n
