Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque ”under Capacities and
Specifications 0359.
{Warning
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
changing a wheel, remove any rust
or dirt from places where the wheel
attaches to the vehicle. In an
emergency, a cloth or a paper towel
can be used; however, use a scraper
or wire brush later to remove all
rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or
rust build-up. Do not get grease
on the flat wheel mounting
surface or on the wheel nuts or
bolts.
When It Is Time for New
Tires
Factors, such as maintenance,
temperatures, driving speeds, vehicle
loading, and road conditions affect the
wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when the
tires have only 1.6 mm (1/16 in) or
less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. See
Tire Inspection 0312 and Tire
Rotation 0312 for additional
information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors including
temperatures, loading conditions, and
inflation pressure maintenance affect
how fast aging takes place. GM
recommends that tires, including the
spare if equipped, be replaced after six
years, regardless of tread wear. The
tire manufacture date is the last four
digits of the DOT Tire Identification
Number (TIN) which is molded into
one side of the tire sidewall. The first
two digits represent the week (01-52)
and the last two digits, the year. For
example, the third week of the year
2010 would have a four-digit DOT
date of 0310.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park a
vehicle that will be stored for at least
a month in a cool, dry, clean area
away from direct sunlight to slow

7. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel.
{Warning
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
changing a wheel, remove any rust
or dirt from places where the wheel
attaches to the vehicle. In an
emergency, a cloth or a paper towel
can be used; however, use a scraper
or wire brush later to remove all
rust or dirt.
8. Put the wheel nuts back on with the rounded end of the nuts
toward the wheel after mounting
the spare tire.
{Warning
Never use oil or grease on bolts or
nuts because the nuts might come
loose. The vehicle's wheel could fall
off, causing a crash.
9. Tighten each wheel nut by hand. Then use the wheel wrench to
tighten the nuts until the wheel
is held against the hub.
10. Turn the wheel wrench counterclockwise to lower the
vehicle. Lower the jack
completely.
11. Tighten the nuts firmly in acrisscross sequence as shown by
turning the wheel wrench
clockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off.
The wheel nuts should be tightened
with a torque wrench to the proper
torque specification after replacing.
Follow the torque specification
supplied by the aftermarket
manufacturer when using accessory
locking wheel nuts. See Capacities
and Specifications 0359 for original
equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
