Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:
Driving style
Tire inflation pressure
Distance driven
Warning!
Tires should be replaced after 6 years,
regardless of the remaining tread.
Tread depth
Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
1
than
/
in (3 mm).
8
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of
1
approximately
/
in (1.6 mm), at which
16
point the tire is considered worn and
should be replaced.
Recommended minimum tire tread depth:
1
Summer tires
/
in (3 mm)

Winter tires
/
in (4 mm)

Warning!
G
Although the applicable federal motor safety
laws consider a tire to be worn when the
treadwear indicators (TWI) become visible at
1
approximately
/
in (1.6 mm), we recom-
16
mend that you do not allow your tires to
wear down to that level. As tread depth
1
approaches
/
in (3 mm), the adhesion
8
properties on a wet road are sharply
reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
