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 (2 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 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 main-

tenance schedule is highly recommended.
