Warning!
Tires and spare tire should be replaced after
6 years, regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited to:
R
Driving style
R
Tire inflation pressure
R
Distance driven
Tread depth

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

(3 mm).
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 approximately

The recommended minimum tire tread depth
for summer tires is

recommended minimum tire tread depth for
winter tires is

Treadwear indicator
:
appears as a solid
band across the tread.
Storing tires
!
Keep unmounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease
and fuels.
Cleaning tires
!
Never use a round nozzle to power wash
tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire.
