grooves. They will appear as bands when the tread depth
becomes 1/16” (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced. Refer

Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:

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
