separately or in combination, can cause
heat buildup and possible tire failure.

tires, can be identified by the M+S marking
on the tire side wall.
Tire tread depth
Safety information
Warning
If the tire tread depth is too low, driving
safety may be impaired in critical situa-
tions such as aquaplaning or slush on the
road. There is a risk of accident, injury, or
property damage. The tire tread depth may
not fall below 0.12 in/3 mm for summer
tires and 0.16 in/4 mm for winter and
all-season tires, or observe the statutory
regulations on minimum tread depth.
Minimum tread depth
You can check the minimum tread depth on
your tires using the wear indicators.
The tire manufacturer’s wear indicators
are distributed over the tire circumference.
These indicators have a height of min.
0.06 in/1.6 mm and serve as an indicator
for tire tread wear.
The positions of the wear indicators are
marked on the tire sidewall with TWI, Tread
Wear Indicator.
Tire damage
General information
Check your tires regularly for damage, for-
eign objects lodged in the tread, and tread
wear.
The following abnormalities may indicate
tire damage or a malfunction on the vehicle:
– Unusual vibrations.
– Unusual tire or running noises.
– Unusual vehicle handling such as a
strong tendency to pull to the left or
right.
– Uneven wear pattern, e.g., increased
wear near tire shoulder.
Tire damage can be caused by situations
such as the following:
– 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
control. There is a risk of accident, in-
