High-Speed Operation; Tire Inspection And Rotation - Pontiac 2007 G6 Owner's Manual

High-Speed Operation

CAUTION:
{
Driving at high speeds, 100 mph (160 km/h)
or higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause
sudden tire failure. You could have a crash
and you or others could be killed. Some
high-speed rated tires require inflation
pressure adjustment for high speed
operation. When speed limits and road
conditions are such that a vehicle can be
driven at high speeds, make sure the tires
are rated for high speed operation, in
excellent condition, and set to the correct
cold tire inflation pressure for the
vehicle load.
Set the cold tire inflation pressure to
35 psi (241 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 288 and Inflation - Tire Pressure
on page 379.

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 383 and Wheel
Replacement on page 388 for more information.
