SNOW TIRES SNOW TIRESSNOW TIRES SNOW TIRES
SNOW TIRESIf you equip your car with snow tires, they
should be the same size and have the same
load capacity as the original tires. Snow tires
should be installed on all four wheels; other-
wise, poor handling may result.
Snow tires should carry 4 psi (28 kPa) more air
pressure than the pressure recommended for
the standard tires on the tire label on the driver
side center pillar outer panel, or up to the
maximum pressure shown on the tire sidewall
whichever is less.
Do not drive faster than 75 mph (120 km/h)
when your car is equipped with snow tires.
I050A01S-AAT
TIRE CHAINS TIRE CHAINSTIRE CHAINS TIRE CHAINS
TIRE CHAINSTire chains, if necessary, should be installed on
the front wheels. Be sure that the chains are the
proper size and that they are installed in accor-
dance with the manufacturer's instructions.
To minimize tire and chain wear, do not con-
tinue to use tire chains when they are no longer
needed.

TIRE ROTATION TIRE ROTATIONTIRE ROTATION TIRE ROTATION
TIRE ROTATION
Tires should be rotated every 7,500 miles
(12,000 km). If you notice that tires are wearing
unevenly between rotations, have the car
checked by a Hyundai dealer so the cause may
be corrected.
SSA8050A
After rotating, adjust the tire pressures and be
sure to check the wheel nut torque.

TIRE BALANCING TIRE BALANCINGTIRE BALANCING TIRE BALANCING
TIRE BALANCINGA tire that is out of balance may affect handling
and tire wear. The tires on your Hyundai were
balanced before the car was delivered but may
need balancing again during the years you own
the car.
Whenever a tire is dismounted for repair, it
should be rebalanced before being reinstalled
on the car.

TIRE TRACTION TIRE TRACTIONTIRE TRACTION TIRE TRACTION
TIRE TRACTIONTire traction can be reduced if you drive on
worn tires, tires that are improperly inflated or
on slippery road surfaces. Tires should be re-
placed when tread wear indicators appear. To
reduce the possibility of losing control, slow
down whenever there is rain, snow or ice on the
road.

Wear indicator
The original tires on your car have tread wear
indicators. The tread wear indicators appear
when the tread depth is 0.06 in. (1.6 mm). The
tire should be replaced when these appear as a
solid bar across two or more grooves of the
tread. Always replace your tires with those of
the recommended size. If you change wheels,
the new wheel's rim width and offset must meet
Hyundai specification.

National Highway Traffic Safety Administration

All passenger vehicle tires must conform to
Federal Safety Standards in addition to these
grades. These quality grades are molded on the
sidewall.
Treadwear - Treadwear -Treadwear - Treadwear -
Treadwear - The tread wear grade is a com-
parative rating based on the wear rate of the tire
when tested under controlled conditions on a
specified government test course. For exam-
ple, a tire graded 150 would wear one and a half
(1 - 1/2) times as well on the government
course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual condi-
tions of their use, however, and may depart
significantly from the norm due to variations in
driving habits, service practices and differenc-
es in road characteristics and climate.Traction AA, A, B, C - Traction AA, A, B, C -Traction AA, A, B, C - Traction AA, A, B, C -
Traction AA, A, B, C - The traction grades,
from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfac-
es of asphalt and concrete. A tire marked C
may have poor traction performance.

Temperature A, B, C - The temperature grades
are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and
its ability to dissipate heat when tested under
controlled conditions on a specified indoor lab-
oratory 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 Fed-
eral 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.
