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.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear
is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and ‘‘Wheel Replacement” later
in this section for
more information.
If your vehicle has dual rear wheels,
also see “Dual ‘Tire Operation” later
in this section.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.
If
your vehicle has single rear wheels, always use one of
the correct rotation patterns
shown here when rotating
your tires.
If your vehicle has front [Ires with different load ranges
or tread designs (such as all season vs. on/off road) than
the rear tires, don’t rotate your tires front to rear.

If your vehicle has dual rear wheels and the load range
and tread design for your front tires is the same as your
rear tires. always
use one of the correct rotation patterns
shown here when rotating your tires.
11 If your vehicle has dual rear
Q
wheels and the load range
or tread design for
your
~ front tires is different from
your rear tires, always use
the correct rotation pattern shown here when rotating
your tires.
The dual tires are rotated
as a pair, and the inside rear
tires become the outside rear tires.
When
you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined up.
After the tires have been rotated, adjust the front and rear
inflation pressures as shown on the Certificatiomire
label. Make certain that
all wheel nuts are properly
tightened. See “Wheel
Nut Torque” in the Index.
ProCarManuals.com
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after
100, 1,000 and 6,000 miles ( 160, I 600 and IO 000
km) of driving. 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.
A CAUTION:
I
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch fire.
You or others could be injured. Be sure
all tires
(including the spare, if any) are properly inflated.
Buying New Tires
To find out what kind and size of tires you need, look at
the Certificntion/Tire label.
Tlze tires installed
on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number
on each tire's sidewall. When you get new tires,
get ones
with that same TPC Spec number. That way
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design,
the TPC number will be followed by an "MS"
(for mud and snow).
If you ever replace your tires with those not having a
TPC
Spec number, make sure they are the same size,
load range, speed rating and construction type
(bias,
bias-belted or radial) as your original tires.
