When It Is Time For New Tires - Hummer 2009 H3 Owner's Manual

5-58 Service and Appearance Care
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here. Do not
include the spare tire 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 5-51 and Loading the
Vehicle on page 4-35.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on page 5-54.
Make certain that all wheel
nuts are properly tightened.
See "Wheel Nut Torque" under
Capacities and Specifications
on page 5-96.
{
CAUTION
Rust or dirt on a wheel, or
on the parts to which it is
fastened, can make wheel
nuts become loose after time.
The wheel could come off and
cause an accident. When you
change a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, you
can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if needed, to get all the
rust or dirt off. See Changing
a Flat Tire on page 5-66.
When It Is Time for
New Tires
Various factors, such as
maintenance, temperatures,
driving speeds, vehicle loading,
and road conditions influence
when you need new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear when
the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
