causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure not to
squash the tyre sidewalls. If this cannot be
avoided, drive slowly over obstacles, e.g.
kerbs, and only at an obtuse angle. You could
otherwise damage the wheel rims and tyres. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure. Pay
particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of the tyre (Y page 359). If necessary, turn
the front wheels to full lock in order to inspect the inner side of the tyre surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not fit
anything onto the valve other than the stand-
ard valve cap or other valve caps approved for
your vehicle by Mercedes-Benz. Do not fit any other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 362).Observe the notes on the emergency spare
wheel (Y page 389).
The service life of tyres depends on various
factors, including the following:
R driving style
R tyre pressure
R mileage Notes on the tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These Operation
