wheel alignment GMC JIMMY 1997 Owner's Manual

I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or n101-e. Also. check the
tire pressure
of the spare tire.
I! you have a compact spare tire. it should be at 60 psi
(420
k Pa).
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 thcm. Radial tires may look
properly inflated even when they're underintlatecl.
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 s11o111d be rotated every 6,000 to 8,000 miles
( IO 000 to 13 000 km). Any time you notice unusual
we;^. rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See "When 1t.s Time for New Tires" and
"Wheel Replacement" later
in this section for
more information.
Thc purpose
of' reg~~lar rotation is to achieve more
uniform wear
fur all tires on the vehicle. The first
rotation
is thu most important. See "Schecluled
Maintenance Services"
in the Index for scheduled
rotation intervals.

Traction -- A, B, C
The tmction grades, from highest to lowest. are A, B. and
C, and they represent the tire‘s ability to stop on wet
pavement
as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction perf’ormance.
Wxning: The traction grade assigned
to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (tuning) traction.
Temperature -- A, B, C
The temperature grades are A (,the highest), B, and C.
representing the tire‘s resistance to the gencration of
heat and its ability to dissipate heat when tested undcr
controlled conditions
on a specified indoor laboratory
test wheel. Sustained high temperature can cause
the
material of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire
failure. The grade
C corresponds to a level of
performance which all passenger car tires must meet
under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance
on the laboratory test wheel than the
minimum required
by law.
Warnin?: Thc ten~perat~u-e pxde for this tire is
estnblishcd for a tire that is properly intlated and not
overloaded. Excessive speed. underinflation, or
excessive loading. either separatcly or in combination.
c;m ca~~se heat buildup
md possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
care1’uIly at the factory to give you the longest tire life
and best overdl performance.
lee1 Replacement
~epl~e ;my wheel that is bent. cracked, or badly rusted
01- corrocled. If wheel n~~ts keep coming loose. the wheel,
wheel bolts and wheel nuts should be 1-eplacec1.
If the
wheel leaks air, replace it (except some aluminum
wheels. which cm sometimes be repaired). See your
GM dcalcr if any of’ these conditions exist.
