This manual is not intended to provide proper training or service procedures for tire
mounting, demounting, balancing, rotation, or repair. Please leave these tasks to
qualified tire service professionals. For your safety and that of others:
• A lways stand well clear of any tire mounting operation. This is especially important
w
hen the service operator inflates the tire. If the tire has been improperly mounted, it
may burst with explosive force causing serious personal injury or death.
• T ires must match the width and diameter requirements of the wheels. For example,
1
6 inch diameter tires must only be mounted to 16 inch diameter wheels. Radial tires
m u
st only be mounted to wheels approved for radial tires.
• W heels must be free of cracks, dents, chips, and rust. Tires must be free of bead
d
amage, cuts, and punctures.
• N ever inflate a tire beyond 40 psi (275 kPa) to seat the beads. Be absolutely certain
b
eads are fully seated before adjusting inflation pressure to the level recommended
for vehicle operation.
• N ever put flammable substances in tire/wheel assemblies at any time. Never put any
f
lammable substance into a tire/wheel assembly and attempt to ignite to seat the
beads.
• A lways stand well away from the work area when tires are being spin balanced either
o
n or off the vehicle.
HIGH PERFORMANCE, LOW ASPECT RATIO TIRES
Many new vehicles come equipped from the factory with high performance and/or low
aspect ratio tires. Generally, these tires provide increased vehicle handling capability,
but may also have numerous engineering performance trade-offs associated with their
designs.
• Lo w aspect ratio tires, with reduced sidewall height, may be more susceptible to
d
amage from potholes, road hazards, and other objects such as curbs. This is true for
the wheels as well. Therefore, as with all other tires, it is important to drive with care
and maintain proper inflation pressure and load conditions. See “Tire Inflation Pres -
sure” and “Tire Damage, Inspection and Service Life” in this manual.
• Some sports cars and other handling performance enhanced vehicles, including s
edans and light trucks/SUVs, may be originally equipped with high performance tires
that are more optimized for warmer weather use. Colder, winter weather traction may
be reduced for these types of tires. Winter tires may be recommended by the vehicle
manufacturer for colder weather application. See “Winter Tires,” the next section in
this manual.
• H igh performance tires may also wear more quickly, ride more firmly, and produce
m
ore noise during operation.
Consult your vehicle Owner’s Manual and tire information placard, or a qualified tire
s e
rvice professional, for more information and specifics regarding these types of tires.

WINTER TIRES
In Winter driving conditions, vehicle control and safe operation under braking and
cornering is especially dependent upon the rear tires. For this reason, Winter tires are
best applied to all wheel positions. Some vehicles have specific recommendations
regarding Winter tire use; consult your vehicle Owner’s Manual and tire information
placard.
• If Winter tires are to be applied to the front axle of any vehicle, they must also be a
pplied to the rear axle for safe operation. This applies to all passenger cars and light
trucks, including Front Wheel Drive (FWD), Four Wheel Drive (4WD) and All Wheel Drive
(AWD) vehicles.
• I f Winter tires are to be applied to the rear axle of any vehicle, it is recommended that
t
hey also be installed on the front axle.
• I t is generally acceptable to apply a tire with a lower speed rating than your original
t
ires for use in Winter weather conditions; however, speed should be reduced accord -
ingly. All Winter tires should be the same speed rating. See “Tire Speed Ratings” in this
m a
nual.
• W inter tires used in warmer, Summer weather conditions may wear more rapidly.
•
Studded Winter tires follow the same recommendations as above; consult a qualified
t
ire service professional for information regarding any seasonal restrictions.
TIRE MIXING
WARNING!
Winter driving presents special challenges for vehicle mobility. The use of winter tires
(including studs and chains)—while improving traction performance in snow and
ice—requires special care with regard to acceleration, braking, cornering, and speed. It
is important to drive with care, not only on snow and ice, but on dry and wet roads as
well.
WARNING!
Driving your vehicle with an improper mix of tires is dangerous. Your vehicle’s handling
characteristics can be seriously affected. You could have an accident resulting in
serious personal injury or death. Consult your vehicle owner’s manual and a qualified
tire service professional for proper tire replacement.

HIGH SPEED DRIVING
• Regardless of the speed and handling capabilities of your car and its tires, a loss of vehicle control can result from exceeding the maximum speed allowed by law or
warranted by traffic, weather, vehicle, or road conditions.
• H igh-speed driving should be left to trained professionals operating under controlled
c
onditions.
• N o tire, regardless of its design or speed rating, has unlimited capacity for speed, and
a
sudden tire failure can occur if its limits are exceeded. See “Tire Speed Ratings,” the
next section in this manual.
Refer to your vehicle Owner’s Manual for any tire pressure recommendations for high
s p
eed driving.
TIRE SPEED RATINGS
A tire bearing a letter “speed rating” designation indicates the tire’s speed capability
according to standardized laboratory tests. This speed rating system is intended to
permit comparison of the speed capabilities of different tires. When replacing your tires,
consult your vehicle Owner’s Manual and tire information placard for recommendations,
if any, concerning the use of speed rated tires.
• To avoid reducing the speed capability of the vehicle, replace a speed rated tire only w
ith another tire having at least the same speed rating. It is the “top speed” of the
“slowest” tire on the vehicle which limits the vehicle’s top speed without tire failure.
• T he tire’s speed rating is void if the tire is repaired, retreaded, damaged, abused, or
o
therwise altered from its original condition. Thereafter, it should be treated as a
non-speed rated tire.
• N on-speed rated tires are usually for ordinary passenger car or light truck service and
n
ot for high speed driving.
• F or winter tires used in cold weather conditions, it is generally acceptable to apply a
t
ire with a lower speed rating than your original tires; however, speed should be
reduced accordingly. All winter tires should be the same speed rating. Some vehicles
have specific recommendations regarding winter tire use; consult your vehicle
Owner’s Manual and tire information placard. See “Winter Tires” in this manual.
These speed ratings are based on standardized laboratory tests under specific,
co
ntrolled conditions. While these tests may relate to performance on the road,
real-world driving is rarely identical to any test conditions. Your tire’s actual speed
capability may be less than its rated speed since it is affected by factors such as inflation
WARNING!
Driving at high speed is dangerous and can cause a vehicle accident, including
serious personal injury or death.

The spare tire in your vehicle is intended to be used as a spare when needed. The spare
tire carrier is not intended to be used for long term storage, except for “temporary use”
tires. If your spare is the same size, load rating, and type of tire as your road tires, it
should be included in the tire rotation process; see “Radial Tire Rotation” in this manual
for more information.
The spare should be included in regular tire inspections and inflation pressure checks.
In
addition, it should be replaced 10 years after date of manufacture, regardless of
condition or tread depth. For more information, see the “Tire Damage, Inspection and
Service Life” in this manual.
TIRE STORAGE
Tires should be stored indoors in a cool, dry place where water cannot collect inside
them. Tires should be placed away from electric generators/motors and sources of heat
such as hot pipes. Storage surfaces should be clean and free of grease, gasoline or other
substances which can deteriorate the rubber.
