SAFETY WARNING
Tell the tire service professional if you have used an aerosol
 xer to in ate/seal the tire. Aerosol  xers could contain
a highly volatile gas. Always remove the valve core
outdoors, away from sources of excessive heat,  ame, or
sparks and completely de ate the tire before removing it
from the wheel.
Speed Rating: The tire’s speed rating is void if the tire is
repaired, retreaded, damaged, abused, or otherwise altered
from its original condition. Thereafter, it should be treated
as a non-speed rated tire. See “Tire Speed Ratings” in this
manual.
Improper repair voids the tire Limited Warranty.
See “Limited Warranty” in this manual.
RFT (Run-Flat Technology) Tires: In addition to the
above, there are recommendations speci c to the repair of
RFT tires; see “RFT Tires with Run-Flat Technology” in
this manual.
TIRE MOUNTING AND OTHER
SERVICING
SAFETY WARNING
Removing and replacing tires on wheels can be dangerous.
Attempting to mount tires with improper tools or proce-
dures may result in a tire explosion causing serious per-
sonal injury or death. This is only a job for a quali ed tire
service professional. Never perform tire service procedures
without proper training, tools, and equipment.
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 quali ed tire service professionals. For your safety
and that of others:
• Always stand well clear of any tire mounting operation.
This is especially important when the service operator
in ates the tire. If the tire has been improperly mounted,
it may burst with explosive force causing serious personal
injury or death.
• Tires must match the width and diameter requirements
of the wheels. For example, 16 inch diameter tires must
only be mounted to 16 inch diameter wheels. Radial tires
must only be mounted to wheels approved for radial tires.
• Wheels must be free of cracks, dents, chips, and rust.
Tires must be free of bead damage, cuts, and punctures.
• Never in ate a tire beyond 40 psi (275 kPa) to seat the
beads. Be absolutely certain beads are fully seated before
adjusting in ation pressure to the level recommended for
vehicle operation.

• Never put  ammable substances in tire/wheel assemblies
at any time. Never put any  ammable substance into
a tire/wheel assembly and attempt to ignite to seat the
beads.
• Always stand well away from the work area when tires
are being spin balanced either on 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.
• Low aspect ratio tires, with reduced sidewall height,
may be more susceptible to damage 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 in ation
pressure and load conditions. See “Tire In ation Pres-
sure” and “Tire Damage, Inspection and Service Life” in
this manual.
• Some sports cars and other vehicles with enhanced
handling performance, including sedans and light trucks/
SUVs, may be originally equipped with high perfor-
mance 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 applica-
tion. See “Winter Tires,” the next section in this manual.
• High performance tires may also wear more quickly, ride
more  rmly, and produce more noise during operation.
Consult your vehicle owner’s manual and tire information
placard, or a quali ed tire service professional, for more
information and speci cs regarding these types of tires.
WINTER TIRES
SAFETY 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.
In winter driving conditions, vehicle control and safe opera-
tion 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 speci c
recommendations regarding winter tire use; consult your
vehicle owner’s manual and tire information placard.
