Wheels, Tires - Mercedes-Benz 190 E 2.3-16 201 1987 Owner's Manual

Wheels, Tires

Replace wheels or tires with the same
designation, manufacturer and type as
shown on the original part.
Warning!
Do not mix different tire construc­
tion types (i.e. radial, bias, and bias-
belted) on your car because handl­
ing may be adversely affected and
may result in loss of control.
See any authorized MERCEDES-
BENZ dealer for information on tested
and recommended wheels and tires for
summer and winter operation. They
can also offer more advice concerning
tire service and purchase.
Front tires should be replaced in sets. If
possible, the spare tire should be used
on the rear wheels. We recommend
that you break in new tires for approx.
100 km (60 miles) at moderate speed.
It is imperative that the wheel mounting
bolts be retightened after approx.
800 km (500 miles). On new vehicles
retightening is carried out during the
1st inspection. Retightening is also
necessary when new wheels are fitted
at a later date, e.g. when the spare
wheel is used for the first time or when
a new set of wheels with M + S tires are
installed.
Tightening torque: 110 Nm (80 Ib-ft).
For tire specifications, refer to "Techni­
cal Data" .
Rotating wheels:
The wheels can be rotated according
to the degree of tire wear while retain­
ing the same sense of rotation. Rotat­
ing, however, should be carried out
before the characteristic tire wear pat­
tern (shoulder wear on front wheels
and tread center wear on rear wheels)
becomes visible at a mileage of
5000-10 000 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 separation,
bulging, etc.. Regular tire pressure
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 pressure than
cold tires. (See tire pressure chart on
fuel filler door and the last page). If a
tire constantly loses air, it should be
inspected for damage.
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
pressure 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.
Note:
When balancing tires, only use the self-
adhering type balancing weights on the
inner side of the rim (see note on fuel
filler flap).
