Tread Wear Indicators
Tread wear indicators are in the original equip-
ment tires to help you in determining when your
tires should be replaced.
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 indica tors, 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
var ying fac tors 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 replacement.
• 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 scheduled maintenance is highly
recommended.
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.
NOTE:
WheelValve 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.
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 recom-
mends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph on
“Tread Wear Indicators” in this section. Ref er to
the Tire and Loading Information placard or the
Vehicle Certification Label 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 found in the
“Tire Safety Information” section of this manual
for more information relating to the Load Index
and Speed Symbol of a tire.
