DRIVING ON STUDDED PASSENGER TIRES – WHERE LEGAL
Only new tires should be fitted with studs. For maximum effectiveness, all four M+S tires on a
vehicle should be fitted with studs. If only the two rear tires are studded, maximum efficiency
in handling and braking will not be realized. NEVER MOUNT STUDDED TIRES ON FRONT
WHEELS ONLY. Refer to the Safety Warnings Section entitles “Application of Winter/Snow Tires
and Studded Winter/Snow Tires”.
TIRE SPINNING IS DANGEROUS
Excessive spinning can cause a tire to “explode”.
Avoid tire spinning. The centrifugal forces created by a rapidly spinning tire can cause an
explosion by tearing the tire apart. These forces act on the complete tire structure and can be of
such magnitude as to break beads, as well as rupturing the entire carcass.
When stuck on ice, snow, mud, or wet grass, etc., the vehicle should be rocked gently
(alternately using forward and reverse gears) with the least amount of wheel spinning.
DO NOT exceed 35 m.p.h. as indicated on the speedometer. Never allow anyone to stand near
or directly ahead of or behind a spinning tire.
Do not spin if a drive wheel is off of the ground. SERIOUS PERSONAL INJURY OR DEATH can
result from the explosion of a spinning tire.
SPEED RATED TIRES
When replacing tires, consult the placard (normally located on a door frame, door edge, or
glove box door) or the owner’s manual for correct size. If the tires shown on the vehicle placard
do not have speed ratings, the appropriate size tire with any speed rating may be applied for
emergency use. When the placard tire size nomenclature contains a speed symbol, for example
P205/60HR15 or P205/60R15 90H, the replacement tire must have the same or higher speed
rating symbol if the speed capability of the vehicle is to be maintained.
IF THE REPLACEMENT TIRE IS NOT SPEED RATED, THE SPEED CAPABILITY OF THE VEHICLE
IS LIMITED BY THE SPEED CAPABILITY OF THE REPLACEMENT TIRE. A Cooper-produced
non-speed rated tire’s maximum speed is 85 m.p.h. (137 km/h). For additional SAFETY and
WARNINGS information, refer to “Speed rated tires” in the Tire Mixing section, above.
TIRE MOUNTING CAN BE DANGEROUS
Tire mounting can be dangerous and should be done by trained persons using proper tools and
procedures. Tire mounting done by an untrained person or using improper tools can lead to tire,
bead and wheel damage. Your tires should be mounted on wheels which are in good, clean
condition. Bent, chipped or rusted wheels may cause tire damage. Have your dealer check the
size and condition of your wheels before mounting new tires. Be sure rim/wheel manufacturer’s
recommendations are followed. The inside of the tire must be free of foreign material. Never
exceed 40psi to seat tire beads when mounting.
Old valves may leak. When new tubeless tires are mounted, have new valves of the correct type
installed. Be sure that all of your valves have suitable valve caps.
The sidewalls of radial tires flex more than non-radial tires. Because of this, tube-type radial tires
require special tubes. Radial tubes should be used with radial tube-type tires. The use of other
tubes not designed for radial tires will result in tube failure causing sudden tire destruction.
Always use a new tube when mounting a new tube-type tire. Do NOT use tubes in Tubeless
type tires.

HIGH PERFORMANCE TIRES
High performance tires are designed with
stiff sidewalls for responsive handling.
Because of stiff sidewalls, it is important
to be sure the top bead is in the rim well
area during mounting. Excessive bead
seat pressures (in excess of 40 psi)
places extreme stresses on tire beads
that are forced onto the rim flange in a
distorted manner. Such stresses may cause damage to tire components and may result in
tire failure. Excessive bead seat pressures (in excess of 40 psi) places extreme stresses on
tire beads that are forced onto the rim flange in a distorted manner. Such stresses may cause
damage to tire components and may result in tire failure.
