Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

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. Pro-
tect tires from contact with oil, grease and gaso-
line.
Cleaning tires
!
Never use a round nozzle to power wash
tires. The intense jet of water can result in dam-
age to the tire.
Always replace a damaged tire.
Tires and wheels
Direction of rotation
Unidirectional tires offer added advan-
tages, such as better hydroplaning perfor-
mance. 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.
i
Spare wheels may be mounted against the
direction of rotation (spinning) even with a unidi-
rectional tire for temporary use only until the reg-
ular drive wheel has been repaired or replaced.
Always observe and follow applicable temporary
use restrictions and speed limitations indicated
on the spare wheel.
