2003 PONTIAC GRAND PRIX wheel torque

Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” under
Capacities and Snncifjcations
on page 5- 102.
Rust or dirt on a wheel, or on ,,le 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.
You need a new tire
if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the

nuts can cause the wheel to come loose
and even come
off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new
GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with
a torque wrench to the
proper torque specification. See ”Capacities
and Specifications” in the Index for wheel nut
torque specification.
Notice: Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification. See “Capacities and
Specifications”
in the index for the wheel nut
torque specification.
