After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire and
Loading Information label. For the location of the tire
and loading information label see Loading Your Vehicle
on page 4-52. Make certain that all wheel nuts are
properly tightened, see “Wheel Nut Torque” under
Capacities and Specifications on page 5-100 for the
proper wheel nut torque specification.
{CAUTION:
Rust or dirt on a wheel, or on the 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 needed, to get all the rust or dirt off. See
Changing a Flat Tire on page 5-71.
Any time you rotate the vehicle’s tires the Tire Pressure
Monitor System (TPMS) will need to be reset. The TPMS
identification codes will need to be matched to tire and
wheel position. See “TPMS Sensor Identification Codes”
under Tire Pressure Monitor System on page 5-59.
When It Is Time for New Tires
One way to tell when it
is 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. Some
commercial truck tires
may not have treadwear
indicators.
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
tire’s rubber.
• The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
• The tire has a bump, bulge, or split.
• The tire has a puncture, cut, or other damage
that cannot be repaired well because of the size
or location of the damage.
