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 5-76 for more information.
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 your vehicle continues to perform
most like it did when the tires were new.
If your vehicle has 235/50ZR18 size tires, GM
recommends rotating these tires at 3,000 mile
(4 800 km) intervals. These tires are optimized for
dry traction and handling performance. Tread life
may be 15,000 miles (24 140 km) or less for these
tires, depending on how and where you drive.
Any time you notice unusual wear, rotate your
vehicle’s 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 5-76 and Wheel Replacement on page 5-81
for more information.
When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
If your vehicle has a compact spare tire, do not
include it in the tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure on page 5-67 and Loading Your Vehicle
on page 4-22.
Reset the Tire Pressure Monitor System. See
Tire Pressure Monitor Operation on page 5-71.
