Warning!
Although the applicable federal motor
safety laws consider a tire to be worn
when the treadwear indicators (TWI) be
1
come visible at approximately /
16
(1.6 mm), we recommend that you do not
allow your tires to wear down to that
level. As tread depth approaches
(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.

TWI (Tread Wear Indicator)
The 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
gasoline.
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.

Direction of rotation

Unidirectional tires offer added advantages,
such as better hydroplaning performance.
To benefit, however, you must make sure the
tires rotate in the direction specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning) of
the tire.
