NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
D
Unusual wear
D
Bad handling
D
Rough ride
D
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire, if equipped.
How to Check
Use a good quality pocket
-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Rims and Wheels
Rims and wheels are stamped with a maximum load
and cold inflation rating. Be sure you don’t exceed
these limits.
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
as indicated:
Your vehicle has hub piloted wheels. Tighten the wheel
stud nuts to the specified torque values at 100 miles
(160 km), 500 miles (800 km) and 1,000 miles
(1 600 km) and then every 1,000 miles
(1 600 km) thereafter.
For proper torque, see “Wheel Nut Torque” in the Index.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
If you’re going to be doing a lot of driving on
high
-crown roads, you can reduce tire wear by adding
5 psi (35 kPa) to the tire pressure in the outer tires. Be
sure to return to the recommended pressures when no
longer driving under those conditions. See “Changing a
Flat Tire” in the Index for more information.
