Caution (Continued)
Tire and/or wheel assembly
damage can occur when coming
into contact with road hazards like
potholes, or sharp edged objects,
or when sliding into a curb. The
warranty does not cover this type
of damage. Keep tires set to the
correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other
road hazards.

All-Terrain Tires

This vehicle may have All-Terrain
Tires. These tires provide good
performance on most road surfaces,
weather conditions, and for off-road
driving. See Off-Road Driving on
page 9-6.
The tread pattern on these tires may
wear more quickly than other tires.
Consider rotating the tires more
frequently than at 12 000 km
(7,500 mi) intervals if irregular
wear is noted when the tires are
inspected. See Tire Inspection on
page 10-68.

Tire Sidewall Labeling

tire is molded into the sidewall.
