Maintenance 153
Failure to properly torque-tighten the
wheel nuts can result in the breakage of
wheel studs and the subsequent loss of
wheels. Loss of vehicle control and seri-
ous personal injury or death can occur.
This check tightening is particularly impor-
tant when rims or brake drums are newly
painted. Paint can flake off from these sur-
faces, causing the nuts to lose their grip
and the wheel to loosen.

Tire Inflation and Wear
Before checking the tires, set the park-
ing brakes, place the transmission in
neutral and block the wheels. Failure to
do so can result in unexpected vehicle
movement and can cause serious per-
sonal injury or death.
WARNING
Check tire pressure when the tire is
cool. Never bleed the air from hot tires.
Increased tire pressure measured in a hot
tire is normal. Low pressures may cause
side wall flexing, resulting in increased
heat, leading to tire failure.
Measure the tread depth. The depth should
not be less than 4/32 in. (3.2 mm) on front
tires and not less than 2/32 in. (1.6 mm) on
drive tires.
It is important to have the wheels correctly
aligned. Check for uneven tire wear fre-
quently. Uneven tire wear is a sign of
wheels out of alignment. Refer to page 184
for examples of typical tire wear.
