Tire Rotation
Recommendations
Tires on the front and rear axles of
vehicles operate at different loads and
perform different steering, driving, and
braking functions. For these reasons,
they wear at unequal rates. These
effects can be reduced by timely
rotation of tires. Rotation will increase
tread life, maintain traction levels and
contribute to a smooth, quiet ride.
To resolve this problem, tires should be
rotated at each service interval
(approximately every 10,000 miles
[16,000km]). More frequent rotation is
permissible if desired. The reasons for
any rapid or unusual wear should be
corrected prior to rotation being
performed.
Tire Rotations Not Recommended -
If Equipped
Due to different size tires and wheels on
front and rear axles tire rotation is not
possible for:
2.9 L V6 Engine Equipped with 19”
tires and wheels
Caution!
Damage to the vehicle may occur if 19”
front and rear tires are rotated
Tire rotation contributes to the
preservation of the grip and traction
performance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tires
identify the cause and correct it as soon
as possible, by contacting an
authorized dealer.

UNIFORM TIRE
QUALITY GRADES
The following tire grading
categories were established by the
National Highway Traffic Safety
Administration. The specific grade
rating assigned by the tire's
manufacturer in each category is
shown on the sidewall of the tires
on your vehicle.
All passenger vehicle tires must
conform to Federal safety
requirements in addition to these
grades.
Treadwear
The Treadwear grade is a
comparative rating, based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The
relative performance of tires
depends upon the actual
conditions of their use, however,
and may depart significantly from
