Valves help to maintain tyre pressure, vehicle safety and tyre life.
The valve in your wheel and tyre assembly is a small but very important part of your vehicle. It holds the pressure inside the tyre assembly and is the access point for regulating your tyre pressure. A valve cap in good condition is also essential as it provides the primary seal and prevents dirt from getting inside.
Rubber valves deteriorate with age and use. During use the valve may become damaged or worn but will inevitably deteriorate through ageing and the force it is subjected to while driving. They are relatively inexpensive yet vital to the performance of tyres. It's therefore recommended by manufacturers to replace valves every time your tyres are changed.
The first sign that your wheels may be out of balance is when your steering wheel starts to wobble above a certain speed. The light weight of modern cars means that they don't dampen down the vibrations caused by spinning wheels in the way that older, heavier vehicles could.
