Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-pro‐
file tires.
Indications of tire damage or other vehicle mal‐
functions:
▷ Unusual vibrations.
▷ Unusual tire or running noises.
▷ Unusual handling such as a strong tendency
to pull to the left or right.
Damage can be caused by the following situa‐
tions, for instance:
▷ Driving over curbs.
▷ Road damage.
▷ Tire inflation pressure too low.
▷ Vehicle overloading.
▷ Incorrect tire storage.
Safety information
WARNING
Damaged tires can lose tire inflation pressure,
which can lead to loss of vehicle control. There
is a risk of an accident. If tire damage is sus‐
pected while driving, immediately reduce speed
and stop. Have wheels and tires checked. For
this purpose, drive carefully to the nearest deal‐
er’s service center or another qualified service
center or repair shop. Have vehicle towed or
transported as needed. Do not repair damaged
tires, but have them replaced.
WARNING
Tires can become damaged by driving over ob‐
stacles, e.g., curbs or road damage, at high
speed. Larger wheels have a smaller tire cross-
section. The smaller the tire cross-section, the
higher the risk of tire damage. There is a dan‐
ger of accidents and property damage. If possi‐
ble, drive around obstacles, or drive over them
slowly and carefully.
Changing wheels and tires
Mounting
Have mounting and wheel balancing carried out
by a dealer’s service center or another qualified
service center or repair shop.
