handling characteristics. If you find no
signs of damage, have the tires and wheels
checked at a qualified specialist workshop.
When parking your vehicle, make sure that
R
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive
over curbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tires, particularly the
sidewalls, may be damaged.
Regular checking of wheels and tires
G WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check the wheels and tires of your vehicle for
damage at least once a month, as well as after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tire pressure. Pay
particular attention to damage such as:
cuts in the tires
R
punctures
R
tears in the tires
R
bulges on tires
R
deformation or severe corrosion on wheels
R
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire ( page 279). If necessary, turn the
Y
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benz for your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary ( page 281).

The service life of tires depends, among other
things, on the following factors:
driving style
R
tire pressure
R
distance covered

Important safety notes on the tire
tread
G WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
Summer tires: â in (3 mm)
R
M+S tires: ã in (4 mm)
R
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Bar indicator : for tread wear is integrated
into the tire tread.
Treadwear indicators (TWI) are required by
law. Six indicators are positioned on the tire
tread. They are visible once the tread depth is
