Operation
Tires and wheels

ț When replacing individual tires, you
should mount new tires on the front
wheels first.
The tire inflation pressure should be
checked regularly, i.e. at least each time
you refuel the vehicle. The preferred inter-
val for checking the tire inflation pressure,
however, is before each trip.
For more information on checking tire in-
flation pressure, refer to "Recommended
tire inflation pressure" (୴ page 210).
Tire inspection
Every time when checking the tire inflation
pressure, the tires should also be inspect-
ed for the following:
ț excessive treadwear, refer to "Tread
depth". the condition of the tread
depths, i.e. uneven tread wear or ex-
cessive treadwear on one side. Turn
the front wheels to full lock if neces-
sary to enable you to check the inner
edge of the front tires more easily. You
must also always check the inside of
the tire tread on the rear wheels.
ț cord or fabric showing through the
tire’s rubber
ț bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
ț foreign objects between the tires
(on vehicles with twin tires)
Replace the tire if any of the above condi-
tions is found.
Also inspect the spare tire periodically for
condition and inflation. Spare tires will age
and become worn over time even if never
used, and thus should be inspected and re-
placed when necessary.
Tire damage
Tire damage can be caused
by:
ț the vehicle’s operating conditions
ț tire aging
ț curbs
ț foreign objects
ț insufficient or excessive tire pressures
ț weather and environmental influences
ț contact with oil, grease, fuel, etc.
Tire care and maintenance
Warning G
Regularly check the tires for damage. Dam-
aged tires can cause tire inflation pressure
loss. As a result, you could lose control of
your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Warning G
Driving over curbs or sharp-edged objects
can cause damage to the tire substructure
which is not visible from the outside.
Damage to the tire substructure cannot be
detected until later and can cause the tire to
burst.
