Tire Inspection and Rotation
Tire rotation is not recommended if your vehicle
has the following performance tire combinations:
•
P235/50R17 size tires on the front wheels
and P255/45R17 size tires on the rear
wheels.
•
P235/50R18 size tires on the front wheels and
P255/45R18 size tires on the rear wheels.
•
P255/45R18 size tires on the front wheels and
P275/40R19 size tires on the rear wheels.
Different tire sizes should not be rotated front to
rear. Each tire and wheel should only be used
in the original front or rear position it is in.
Tire rotation is recommended if your vehicle is
equipped with P235/50R17 size tires on all
four wheel positions or 255/45ZR18 size tires on
all four wheel positions. These tires should be
rotated every 5,000 to 8,000 miles (8 000 to
13 000 km)
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
See
When It Is Time for New Tires on page 440
and Wheel Replacement on page 445 for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
first rotation is the most important. See
Scheduled
Maintenance on page 505 .
