the tires have been rotated. See
Tire Pressure on page 10-51
andVehicle Load Limits on
page 9-14.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10-54.

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.

When reinstalling the regular wheel
and tire, also reinstall either the
center cap or the bolt-on hub cap,
depending on which one the
vehicle has.
.For center caps, line up the tab
on the center cap with the slot in

.For bolt-on hub caps, line up the
plastic nut caps with the wheel
nuts and tighten clockwise by
hand to get them started. Then
tighten with the wheel wrench
