SPEED RATINGS
Speed Symbols are shown on the
sidewall of some Uniroyal
®
tires.
The following table shows the
maximum speed corresponding to
the symbol.
*Some V (or VR) rated tires may
have a speed capacity greater
than 149 mph (240 km/h). Consult
your participating Uniroyal tire
retailer for maximum speed rating
if your vehicle capability exceeds
this speed.
**Z (or ZR) rated tires are designed
to use on cars with maximum
speed capabilities in excess of 149
mph (240 km/h).
(W and Y speed ratings are sub-categories of Z).
Consult your Uniroyal tire retailer for maximum speed capabilities.
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 underin ated, overloaded, worn out, damaged,
altered, improperly repaired, or retreaded. Furthermore, a tire’s speed
rating does not imply that vehicles 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.
Uniroyal
®
highway passenger tires that do not have a speed symbol on the
sidewall have a maximum speed rating of 105 mph (170 kph). Light truck
highway tires that do not have a speed symbol on the sidewall of the tire
have a maximum speed rating of 87 mph (140 kph).
Uniroyal
®
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/h). Winter
tires with a speed symbol have a maximum speed rating in accordance
with the symbol.
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
 tted as original equipment (as indicated on the vehicle tire placard or
owner’s manual). If tires with lower speed ratings are  tted, 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 above table.
REMEMBER…High speed driving can be dangerous and may damage your tires.
AND…When driving at highway speeds, correct in ation pressure is
especially important.
