Maintenance and care of wheels and tires
321
Directives to be observed
Damaged wheels can cause a loss of tire
pressure.
ROnly mount tires and wheels of the same
type and make.
ROnly mount tires of the correct size onto
the wheels.
RAfter mounting new tires, run them in at
moderate speeds for the first 60 miles
RRegularly check the tire tread depth and
the condition of the tread across the whole
width of the tire (Y page 321). If necessary,
turn the front wheels to full lock in order to
inspect the inner side of the tire surface.
RAll wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything on the valve (such as tire
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your
vehicle.
(100
km) as they only reach their full
performance after this distance.
RDo not use tires until they are excessively
worn as the tire traction on wet road
surfaces decreases significantly when the
tread depth is less than 1/8 in (3 mm).
RRegularly check the pressure of all the tires
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correct the pressure as necessary
RIf the vehicle is heavily laden, check the tire
pressure and adjust it if necessary.
RWhen parking your vehicle, make sure that
the tires do not get deformed by the curb
or other obstacles. If it is necessary to drive
over curbs, speed humps or similar
elevations, try to do so slowly and at an
obtuse angle. Otherwise, the tires,
particularly the sidewalls, can get
damaged.

Service life of tires
The service life of tires depends on the
following factors amongst other things:
Rdriving style
Rtire pressure
Rmileage
Maintenance and care of wheels and
tires
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel/spare wheel.
Checking wheels and tires
G Warning
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Tire tread
G Warning
Although the applicable federal motor vehicle
safety laws consider a tire to be worn when
the tread wear indicators (TWI) become
visible at approximately 1/16 in (1.6 mm), we
recommend that you do not allow your tires
to wear down to that level. As tread depth
approaches 1/8 in (3 mm), the adhesion
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
RRegularly check the wheels and tires of
your vehicle for damage (e.g. cuts,
punctures, tears, bulges on tires and
deformation or severe corrosion on
wheels), at least once a month, as well as
after driving off-road or on rough roads.
properties on a wet road are sharply reduced.
