Notes on tyre pressure

Driving with tyre pressure that is too high or too low can:

Shorten the service life of the tyres
Cause increased tyre damage
Adversely affect handling characteristics and thus driving safety, e.g. due to aquaplaning

WARNING Risk of accident due to repeated pressure drop in the tyres

The wheels, valves or tyres could be damaged.

Too low a tyre pressure can lead to the tyres bursting.

Examine the tyres for foreign objects.

Check whether the tyre has a puncture or the valve has a leak.

If you are unable to rectify the damage, contact a qualified specialist workshop.

Information on the recommended tyre pressure for the vehicle's factory-fitted tyres can be found on the tyre pressure table in the fuel filler flap and in the tyre pressure tables More.

Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure.

Vehicles with a tyre pressure monitor: you can also check the tyre pressure using the on-board computer.

Only correct tyre pressures when the tyres are cold. Conditions for cold tyres:

The vehicle has been parked with the tyres out of direct sunlight for at least three hours.
The vehicle has travelled less than 1.6 km.

A rise in the tyre temperature of 10 °C increases the tyre pressure by approx. 10 kPa (0.1 bar/1.5 psi). Take this into account when checking the tyre pressure of warm tyres.

Notes on trailer operation

The applicable tyre pressure for the tyres of the rear axle is always the recommended tyre pressure for a full load.
