Use the tyre pressure recommended for cold tyres in order to achieve optimal tyre performance and optimal wear.
To avoid incorrect tyre pressure, the pressure should be checked on cold tyres. "Cold tyres" means the tyres are the same temperature as the ambient temperature (approx. 3 hours after the car has been driven). After a few kilometres of driving, the tyres warm up and the pressure increases.
Remove the cap from the valve on one tyre and then press the tyre pressure gauge firmly down onto the valve.
Inflate to the recommended pressure.
Refit the dust cap.
- After a tyre has been inflated, always refit the dust cap in order to avoid damage to the valve from gravel, dirt, etc.
- Only use plastic dust caps. Metal dust caps can rust and become difficult to unscrew.
Check the tyres visually for any implanted nails or other objects that could puncture the tyre and cause leakage.
Check the sidewalls for any cavities, cuts, bumps or other irregularities.
Repeat this for all tyres, including the spare tyre*.
If you have over-inflated, release air by pressing in the metal pin in the centre of the valve. Then check the pressure again using the tyre pressure gauge.
