356 STARTING AND OPERATING

Tread Wear Indicators

Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the indicators appear in
two or more adjacent grooves, the tire should be re-
placed.
Many states have laws requiring tire replacement at this
point.

Life Of Tire

The service life of a tire is dependent upon various
factors including but not limited to:
• Driving style
• Tire pressure
• Distance driven
