SERVICING AND MAINTENANCE 271
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h), or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.
Tire Tread
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced.
Refer to “Replacement Tires” in this section for further
information.
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 pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment
Distance driven
Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle sched-
uled maintenance is highly recommended
NOTE:
Wheel valve stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may cause tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.
1 — Worn Tire
2 — New Tire
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.
