B.F. Goodrich Tire Automobile Parts User Manual

Although a tire may be speed-rated, we do not endorse the
operation of any vehicle in an unsafe or unlawful manner.
Speed ratings are based on laboratory tests which relate to
performance on the road, but are not applicable if tires are
underinflated, overloaded, worn out, damaged, altered,
improperly repaired, or retreaded. Furthermore, a tire's
speed rating does not imply that a vehicle can be safely
driven at the maximum speed for which the tire is rated,
particularly under adverse road and weather conditions or if
the vehicle has unusual characteristics.

Winter Tires – BFGoodrich
®
brand winter tires that do not have
a speed symbol on the sidewall or tires with Q symbols have a
speed rating of 100 mph (160 km/hr). Winter tires with a speed
symbol have a maximum speed rating in the accordance with
the symbol.
Studded tires have a maximum speed rating of 93 mph (150 km/hr).
The speed and other ratings of retreaded tires are assigned by
the retreader and replace the original manufacturer’s ratings.
IMPORTANT: In order to maintain the speed capability of
the vehicle, replacement tires must have speed ratings
equal to or higher than those fitted as original
equipment (as indicated on the vehicle tire placard or in
the owner's manual). If tires with lower speed ratings
are fitted, the vehicle’s handling may be affected and the
speed capability of the vehicle will be lowered to the
maximum speed capability of the replacement tires as
indicated in the foregoing table.
REMEMBER...High speed driving can be dangerous and may
damage your tires.
AND...When driving at highway speeds, correct inflation
pressure is especially important.
