After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure on page 5-64 and Loading the Vehicle on
page 4-19. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-114.
{ CAUTION:
Rust or dirt on a wheel, or on the parts
to which it is fastened, can make wheel
nuts become loose after 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 5-82.
If your vehicle has a Tire Pressure Monitor
System (TPMS), reset the TPMS sensors after
rotating the tires. See Tire Pressure Monitor
Operation on page 5-67.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. See Storing a Flat or
Spare Tire and Tools on page 5-97.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which appear
when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
Some commercial truck tires, including Goodyear
LT225/75R16 G949 RSA and Goodyear LT225/75R16
G933 RSD, may not have treadwear indicators. If the
tires do not have treadwear indicators, replace the tires
when the tread depth is down to 1/8 inch (3.2 mm) for the
front tires, or 1/16 inch (1.6 mm) for the rear tires.
