Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs
of wear or damage. See When It Is Time for
New Tires on page 5-73 for more information.
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.
•
P235/50ZR18 size tires on the front wheels
and P255/45ZR18 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 the 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).
See Scheduled Maintenance on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This
will ensure that the vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate
your tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
