Hummer 2004 H2 - Manual (Page 384)

After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certification/Tire label or Tire and Loading Information
label. See Loading Your Vehicle on page 4-67.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under Capacities and
Specifications on page 5-111.
{ CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a 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 you need to, to
get all the rust or dirt off. See “Changing a Flat
Tire” in the Index.
When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining. Some
commercial truck tires may
not have treadwear
indicators.
