The correct tyre pressure is vital for both safety and for extending the life of your tyre.
You should check your tyre pressures monthly, including the spare and before any long distance driving. Make sure the tyre pressures match the pressures recommended by the vehicle manufacturer.
Tyre pressures should if possible be checked cold.If tyre pressures are checked hot, add 4 to 5 psi(0.3 bar) to the recommended pressures.
In the case of unusual pressure loss, the internal and external condition of thetyre should be checked, as well as the condition of the wheel and valve.
Maximum grip on the road is vital for road safety. This can only be achieved with the correct pressure in your tyres. Fig. 3 shows how much grip a tyre has on the road depending on its pressure.
