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 mini-
mum tread depth.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Minimum tread depth
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.
Warning
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately
or in combination, can cause heat buildup
and possible tire failure.
The positions of the wear indicators are
marked on the tire sidewall with TWI, Tread
Wear Indicator.
Tire damage
M+S
Winter tires, as well as all-season tires with
better winter performance than summer tires,
can be identified by the M+S marking on the
tire side wall.
General information
Check your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.

Unusual vehicle handling such as a strong
tendency to pull to the left or right.
▷
Uneven wear pattern, e.g., increased wear
in the area of the tire shoulder.
If the tire tread depth is too low, driving
safety may be impaired in critical situations
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
Damage can be caused by the following situa-
tions, for instance:
