TION PRESSURES
Tire label located on the driver's side
center pillar outer panel gives the cold
tire pressures recommended for your
vehicle with the original tire size, the
number of people that can be in your
vehicle and vehicle capacity weight.

These pressures were chosen to pro-
vide the most satisfactory combination
of ride comfort, tire wear and stability
under normal conditions. Tire pressures
should be checked at least monthly.
Proper tire inflation pressures should
be maintained for these reasons:

!
CAUTION:
Always observe the following:
o Check pressures when the tires
are cold. (After the vehicle has
been parked for at least three hours
or hasn't been driven more than 1
mile (1.6 km) since starting up.)
o Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
o Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been dam-
aged, replace them.
!
WARNING:
Overinflation or underinflation can
reduce the tire life, adversely affect
vehicle handling, and lead to sud-
den tire failure. This could rusult in
loss of vehicle control and potential
injury.
!
WARNING:
o Inspect your tires frequently for
proper inflation as well as wear
and damage. Always use a tire
pressure gauge.
o Tires with too much or too little
pressure wear unevenly causing
poor handling, loss of vehicle
control, and sudden tire failure
leading to accidents, injuries, and
even death. The recommended
cold tire pressure for your vehicle
can be found in this manual and
on the tire label located on the
driver's side of the center pillar.
o Worn tires can cause accidents.
Replace tires that are worn, show
uneven wear, or are damaged. See
page 8-11.
o Remember to check the pressure
of your spare tire. Hyundai recom-
mends that you check the spare
every time you check the pressure
of the other tires on your vehicle.NOTE:
o Underinflation also results in ex-
cessive wear, poor handling and
reduced fuel economy. Wheel de-
formation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by your
Hyundai Dealer.
o Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.

Remove the valve cap from the tire
valve stem. Press the tire gauge firmly
onto the valve to get a pressure mea-
surement. If the cold tire inflation pres-
sure matches the recommended pres-
sure on the tire and loading information
label, no further adjustment is neces-
sary. If the pressure is low, add air until
you reach the recommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the center
of the tire valve. Recheck the tire pres-
sure with the tire gauge. Be sure to put
the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.
I035A01JM-AATCHECKING TIRE INFLATION PRES-
SURE
Check your tires once a month or more.
Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality gauge to check tire
pressure. You cannot tell if your tires
are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they're underinflated.
Check the tire's inflation pressure when
the tires are cold. - "Cold" means your
vehicle has been sitting for at least
three hours or driven no more than 1
mile (1.6 km).Federal law requires tire manufacturers
to place standardized information on
the sidewall of all tires. This information
identifies and describes the fundamen-
tal characteristics of the tire and also
provides the tire identification number
(TIN) for safety standard certification.
The TIN can be used to identify the tire
in case of a recall.

rubbercoated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester, and
others. The letter "R" means radial
ply construction; the letter "D" means
diagonal or bias ply construction;
and the letter "B" means belted-bias
ply construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation pres-
sure. 1. Manufacturer or Brand name

7. Uniform Tire Quality Grading
(UTQG):
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance. For more
information, see Uniform Tire Qual-
ity Grading on page 8-14.
