Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly checkt he tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 252). In order to inspec tthe
inne rside of the tire surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not install
anythin gontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benzf or your vehicle. Do not use any other valve
caps or systems ,e.g. tire pressure monitoring
systems.
You should regularly checkt he pressure of all
your tires includin gthe spare wheel, particularly
prior to long trips. Adjust the tire pressure as
necessary (
Ypage 254).
The servicel ife of tires depends, among other
things, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tir etread
GWARNING
Insufficientt ire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces,t he risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit differentl evels of wear at differ-
ent location sonthe tire tread. Thus, you
should regularly checkt he tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons ,replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated int othe tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible onc eatread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size ont othe
wheels.
RBreak in new tires at moderates peeds for the
first 60 miles (100 km). The new tires only
reach their full performanc eafter this dis-
tance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear. This also applies to the
spare wheel.
Winter operation
General notes
Have your vehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (
