of performance on the laboratory test
wheel than the minimum required by
law.
Inspect your tires frequently for signs of
damage, foreign objects and tread
wear, and check tread depth.
The temperature grade for this tire
is established for a tire that is
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 a
flat tire or some other vehicle malfunc-
tion. This type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced 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.<
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.<
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.<
RSC - Run Flat tires
Temperature
Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC, refer to page 135.
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.
M+S
Winter and all-season tires. These have
better winter driving properties than
summer tires.
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.
