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
The traction grade assigned to

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

Excessive speed, under-inflation, or

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.<
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.
