The tyres can burst.
The tyres can wear excessively and/or unevenly.
The driving characteristics as well as the steering and braking characteristics may be greatly impaired.
monthly
when the load changes
before embarking on a longer journey
if operating conditions change, e.g. off-road driving
Shorten the service life of the tyres
Cause increased tyre damage
Adversely affect handling characteristics and thus driving safety, for example, due to aquaplaning
The wheels, valves or tyres could be damaged.
Too low a tyre pressure can lead to the tyres bursting.
Information on the recommended tyre pressure for the vehicle's factory-fitted tyres can be found on the tyre pressure table on the driver's seat base or on the B‑pillar on the driver's side 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 monitoring system: you can also check the tyre pressure using the on-board computer.
Crewbuses with a GVWR of 3.0 t and 3.5 t: when changing from 245/65 R17XL tyres to one of the other approved tyre sizes and vice versa, the permissible pressure range of the tyre pressure monitoring system must be recoded. Contact a qualified Mercedes-Benz specialist workshop for this purpose.
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.
The applicable tyre pressure for the tyres of the rear axle is always the recommended tyre pressure for a full load.
