Car Tyre Valves
Car tyre valves make up one of the key components of the wheel. Air pressure is controlled via the valve. The valve is the final seal to make sure that the car tyres stay inflated. Under-inflated tyres are at risk of blow outs due to increased friction which causes the tyre to heat up and sometimes burst. Tyre valves can only be fitted or replaced by removal of the existing tyre. A UK tyres specialist from one of Grippy’s nationwide fitting centres can do this at the same time as fitting your brand new tyres. It is generally recommended that the valves are replaced at the same time as changing your car or van tyres.
How do car tyres‘ valves work? The valve stem is the tube that sticks out from the rim. This is where you remove the dust cap to inflate the tyre. The valve stem is generally made of rubber although some 4×4 tyres and specialist collectors’ cars are made of metal. As the valve stem is a part which is exposed to elements and some extreme conditions the rubber element is prone to deterioration, which is why it is advisable for these to be changed at every tyre change. The pressure inside the tyre holds the valve shut. The valve is opened by inflating the tyre or by pushing down the small pin in the middle of the valve. Releasing pressure is sometimes necessary when the tyre is over-inflated or driving styles change. If you have come back from a camping holiday where you have inflated the tyres to suit the journey then on the return to normal driving these need to be deflated back to normal pressure.
