Warning G
Although the applicable federal motor
safety laws consider a tire to be worn
when the Treadwear Indicators (TWI) be-
come visible at approximately
1
/
16
in
(1.6 mm), we recommend that you do not
allow your tires to wear down to that lev-
el. As tread depth approaches
1
/
8
in
(3 mm) for summer tires or
1
/
6
in (4 mm)
for winter tires, the adhesion properties
on a wet road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction var-
ies widely.
!CAUTION
Keep unmounted tires in a cool, dry
place with as little exposure to light
as possible. Protect tires from con-
tact with oil, grease and gasoline/
diesel.
!CAUTION
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.
