410 SERVICING AND MAINTENANCE
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation pres-
sures can cause uneven wear patterns to
d
e
velop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have a
r
e
duced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended.
NOTE:
Wheel valve stem must be replaced as well when
in
stalling new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
li
ttle exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly recommends
that you use tires equivalent to the originals in size,
quality and performance when replacement is
needed
Ú
page 409. Refer to the Tire and Loading
Information placard or the Vehicle Certification
La
bel for the size designation of your tire. The Load
Index and Speed Symbol for your tire will be found
on the original equipment tire sidewall.
See the Tire Sizing Chart example for more
information relating to the Load Index and Speed
Symbol of a tire
Ú page 401.
It is recommended to replace the two front tires or
tw
o rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire
de
aler or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre
-
dictable handling and stress to steering and
su
spension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over
-
loading and failure. You could lose control and
h
ave a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.
