Saturn 2007 Ion, Owner'S Manual

Page: 339 / 440

The low-profile performance tires, size
215/45ZR17, require tire inflation pressure
adjustment when driving your vehicle at speeds of
100 mph (160 km/h) or higher. Set the cold tire
inflation pressure to 33 psi (227 kPa) for the front
and rear tires when operating your vehicle at
high-speed conditions.
When you end high-speed driving, return the tires
to the cold inflation pressure shown on the Tire
and Loading Information Label. See Loading Your
Vehicle on page 250 and Inflation - Tire Pressure
on page 337.
Tire Inspection and Rotation
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 341
and Wheel Replacement on page 346 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 391.
When rotating non-directional tires, always use the
correct rotation pattern shown here.
