Tire Pressure All About Valves

As the tires are the only elements that connect the vehicle to the road, it is essential to maintain them properly in order to ensure your safety but also to limit your fuel consumption.

Tire maintenance involves, among other things, adjusting the pressure correctly using the valve attached to the rim.

Typically, the recommended pressure is listed on the driver’s door, inside the fuel door, or in the vehicle’s owner’s manual.

1 - Valves: What Is The Use?

Valves are generally made up of a rubber tip and a cap that screws onto to seal the tire.

They therefore allow air not to escape and prevent the introduction of elements (water, mud, dust) into the tire, thus limiting its deterioration.

Depending on the tire model, they are not fixed in the same place.

On Tubeless type tires, the most common models on passenger vehicles, they are fixed to the rims, while on TubeType type tires, they are fixed directly to the inner tubes.

2 - Types Of Valves

Several types of valves are available on the market.

The most common valves are Schrader-type rubber valves, the ones most commonly found on passenger vehicles. They look like small threaded tubes, in which there is a spring piston, allowing air to escape from the tire.

Now there are also electronic valves on which an electronic sensor (TPMS) is installed and continuously measures the pressure. In the event of a significant drop in pressure, it transmits a radio signal to the on-board computer.

This electronic monitoring system alerts the driver when the tire pressure is not correctly adjusted, thanks to a warning light generally placed on the vehicle’s dashboard.

This system is mandatory on all new car models since November 1, 2012 and on all new vehicles by the end of 2014.

There are also chrome valves, aluminum valves, screw valves.

3 - When To Change The Valves Of Your Pneumatics?

An important element to take into account for tire maintenance is the change of valves. In fact, in good condition, they prevent air loss and ensure the good health of the tire. The valves are partially made of rubber and are subjected to great pressure at high speeds. Cracked or damaged, they risk breaking under the effect of this pressure.

It is therefore recommended to regularly check the condition of the valves and to replace them each time the tire is changed.
