Those grades represent the tire's ability 
to stop on wet pavement as measured 
under controlled conditions on speci-
fied government test surfaces of 
asphalt and concrete. A tire marked C 
may have poor traction performance.

The traction grade assigned to 
this tire is based on straight-

ahead braking traction tests, and does 
not include acceleration, cornering, 
hydroplaning, or peak traction charac-
teristics.

<

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 condi-
tions 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 tem-
perature 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 B and A represent higher levels 
of performance on the laboratory test 
wheel than the minimum required by 
law.

The temperature grade for this tire 
is established for a tire that is 

properly inflated and not overloaded. 
Excessive speed, under-inflation, or 
excessive loading, either separately or 
in combination, can cause heat buildup 
and possible tire failure.

<

Winter and all-season tires. These have 
better winter driving properties than 
summer tires.

Inspect your tires frequently for signs of 
damage, foreign objects and tread 
wear, and check tread depth.

Due to low-profile tires, please 
note that wheels, tires and sus-

pension parts are more susceptible to 
road hazard and consequential dam-
ages.
Unusual vibrations encountered during 
normal vehicle operation can indicate 
tire failure or some other vehicle defect. 
This type of problem can be caused by 
contact with curbs, etc. This is also true 
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or 
right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed 
carefully to the nearest BMW center or 
professional tire center, or have the 
vehicle towed there. Tire damage, up to 
and including blowouts, can endanger 
the lives of both the vehicle occupants 
and other road users.
