TIRES
MAINTENANCE
HEADLIGHT REMOVAL
Inflation pressures should be checked when tires are
cool, using an accurate tire pressure gauge. Check
pressures at regular intervals.
Bleeding the air from hot tires is dangerous and
should not be attempted. While the pressure will be
reduced, an increase in temperature of the tire will take
place as soon as driving is resumed and tire failure will
result.

2. Unhook the headlight retaining spring from the
headlight retainer.
UNDERINFLATION
Too little air pressure increases deflection, causes
the tread to wipe and scuff over the road, results in extra
strain on the tire, and increases the chances for bruising.

TIRE AND WHEEL BALANCE
Front wheel shimmy, wandering, and cupped tires
are caused by an out-of-balance condition of one or both
front tires. If the tires are changed because of a flat tire
or to equalize wear, it is advised that they be checked for
balance before operating the truck.
