Tyre pressure for cars

astuces et conseils petit2 pression des pneus éditorial voiture

A tyre loses some of its pressure through natural causes (typically around 1 psi (0.076 bars) per month). Pressure loss may be accelerated by other air leaks due to:

• an accidental puncture
• the valve: which must be changed each time a tyre is changed.
• the valve cap: essential to guarantee an airtight seal.
• the wheel: which should be cleaned each time a tyre is fitted.
• Follow the advice of the vehicle or tyre manufacturer, particularly with regards to the conditions of use (loads/speeds etc).

• Check pressures when the tyres are cold (tyres which have not been used in the last 2 hours or have covered less than 2 miles (3 km) at low speed). 
• If tyres are hot when they are checked, add 4 to 5 psi (0.3 bar) to the pressure recommended by the vehicle manufacturer. Re-check the pressures when the tyres are cold.
• Never deflate a hot tyre.
• Even if tyres are inflated with nitrogen, the pressures and overall tyre condition must still be checked frequently.

A correctly inflated tyre improves safety, is more economical in use and is better for the environment.

By keeping your tyres at their correct pressure, you’ll reduce your running costs. Under-inflated tyres are prone to overheating use more fuel and wear out more quickly. Likewise, over inflation can reduce tyre life, reduce grip and cause steering problems.

• WEAR
A tyre which is 20% under-inflated can give 20% less mileage. That means a loss of 5,000 miles (8,000 km) on a potential mileage of 25,000 miles (40,000 km).

• FUEL CONSUMPTION AND CO2 EMISSIONS.
Low tyre pressure increases both fuel consumption and CO2 emissions.
