Wheels, Tires
Replace wheels or tires with the same
designation, manufacturer and type
as shown on the original part. See
your authorized MERCEDES-BENZ
dealer for further information.
Warning!
Do not mix different tire construc­
tion types (i.e. radial, bias, and bias-
belted) on your car because hand­
ling may be adversely affected and
may result in loss of control.
See your authorized MERCEDES-
BENZ dealer for information on tested
and recommended wheels and tires
for summer and winter operation.
They can also offer more advice con­
cerning tire service and purchase.
Front tires should be replaced in sets.
If possible, the spare tire should be
used on the rear wheels. We recom­
mend that you break in new tires for
approx. 100 km (60 miles) at moder­
ate speed.
It is imperative that the wheel mount­
ing bolts be retightened after approx.
800 km (500 miles). On new vehicles
retightening is carried out during the
1st inspection. Retightening is also
necessary whenever wheels are fit­
ted, e.g. when the spare wheel is
used for the first time or when a set of
wheels with M + S tires are installed.
Tightening torque: 110 Nm (80 Ib-ft).
For tire specifications, refer to
“ Technical Data” .
Rotating wheels:
The wheels can be rotated according
to the degree of tire wear while retain­
ing the same direction of travel.
Rotating, however, should be carried
out before the characteristic tire wear
pattern (shoulder wear on front
wheels andtread center wear on rear
wheels) becomes visible at a mileage
of 5000 - 1 0 000 km (3000 -
6000 miles) as otherwise the driving
properties deteriorate.
Underinflated tires due to a slow leak
(e.g. due to a nail in the tire) may
cause damage such as tread separa­
tion, bulging, etc. Regular tire pres­
sure checks (including the spare tire)
at intervals of no more than 14 days
are therefore essential. Keep in mind
that warm tires have a higher pres­
sure than cold tires. (See tire pres­
sure chart on fuel filler door and the
last page.) If a tire constantly loses
air, it should be inspected for dam­
age.
Use only genuine MERCEDES-BENZ
wheel bolts (identified by Mercedes-
Star on bolt shaft).
Thoroughly clean the inner side of the
wheels any time you rotate the wheels
or wash vehicle underside.
Dented or bent rims cause tire pres­
sure loss and damage to the tire
beads. For this reason, check rims for
damage at regular intervals.
The rim flanges must be checked for
wear before a tire is mounted.
Remove burrs, if there are any.
