Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and

tire is considered worn and should be re-
placed.
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
Recommended minimum tire tread depth:
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.

the tire.
Although the applicable federal motor safety
laws consider a tire to be worn when the
