Tire damage
General information
Check your tires regularly for damage, foreign
bodies 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
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush-
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if the vehicle is equipped with
low-profile tires.
Indications of tire damage or another vehicle
malfunction:
▷ Unusual vibrations.
▷ Unusual tire or running noises.
▷ Unusual handling such as a strong ten-
dency to pull to the left or right.
▷ Uneven wear pattern, e.g., increased wear
in the area of the tire shoulder.
Damage can be caused by the following situa-
tions, for instance:
▷ Driving over curbs.
▷ Road damage.
▷ Tire pressure too low.
▷ Vehicle overloading.
▷ Incorrect tire storage.

Safety information
Warning
Damaged tires can lose tire inflation pres-
sure, which can lead to loss of vehicle con-
trol. There is a risk of accident. If tire dam-
age is suspected while driving, immediately
reduce speed and stop. Have wheels and
tires checked. To do so, drive carefully to an
authorized service center or another qualified
service center or repair shop. Have vehicle
towed or transported as needed. Do not re-
pair damaged tires, but have them replaced.
Warning
Tires can become damaged by driving over
obstacles, e.g., curbs or road damage, at
high speed. Larger wheels have a smaller tire
cross-section. The smaller the tire cross-sec-
tion, the higher the risk of tire damage. There
may be a risk of accidents and risk of dam-
age to property. If possible, avoid driving over
objects or road conditions that may damage
tires, or drive over them slowly and carefully.
Exchanging wheels and

Mounting and wheel balancing

authorized service center or another qualified
