TIRES AND WHEELS

Tire care

CAUTION

For proper maintenance, safety, and

maximum fuel economy, you must

always maintain recommended tire

inflation pressures and stay within

the load limits and weight distribution

recommended for your vehicle.

• Underinflation also results in

excessive wear, poor handling

and reduced fuel economy.

Wheel deformation also is

possible. Keep your tire pres-

sures at the proper levels. If a

tire frequently needs refilling,

have it checked by an author-

ized HYUNDAI dealer.

Recommended cold tire inflation

pressures

All tire pressures (including the

spare) should be checked when the

tires are cold. “Cold Tires” means the

vehicle has not been driven for at

least three hours or driven less than

one mile (1.6 km).

• Overinflation produces

a

OLM089008N

harsh ride, excessive wear at

the center of the tire tread, and

a greater possibility of dam-

age from road hazards.

All specifications (sizes and pres-

sures) can be found on a label

attached to the driver’s side center

pillar.

Recommended pressures must be

maintained for the best ride, vehicle

handling, and minimum tire wear.

WARNING - Tire underin-

flation

Severe underinflation can lead

to severe heat build-up, causing

blowouts, tread separation and

other tire failures that can result

in the loss of vehicle control

leading to severe injury or

death. This risk is much higher

on hot days and when driving

for long periods at high speeds.

For recommended inflation pressure,

refer to “Tire and wheels” in section

8.

Maintenance

Checking tire inflation pressure

CAUTION

CAUTION - Tire pressure

Always observe the following:

Check your tires once a month or

more.

• Warm tires normally exceed

recommended cold tire pres-

sures by 4 to 6 psi (28 to 41

kPa). Do not release air from

warm tires to adjust the pres-

sure or the tires will be under-

inflated.

• Check tire pressure when the

tires are cold. (After vehicle

has been parked for at least

three hours or hasn't been

driven more than one mile (1.6

km) since startup.)

Also, check the tire pressure of the

spare tire.

How to check

Use a good quality gage to check tire

pressure.You can not tell if your tires

are properly inflated simply by look-

ing at them. Radial tires may look

properly inflated even when they're

underinflated.

• Be sure to reinstall the tire

inflation valve caps. Without

the valve cap, dirt or moisture

could get into the valve core

and cause air leakage. If a

valve cap is missing, install a

new one as soon as possible.

• Check the pressure of your

spare tire each time you check

the pressure of other tires.

• Never overload your vehicle.

Be careful not to overload a

vehicle luggage rack if your

vehicle is equipped with one.

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).

• Worn, old tires can cause acci-

dents. If your tread is badly

worn, or if your tires have

been damaged, replace them.

WARNING - Tire Inflation

Overinflation or underinflation

can reduce tire life, adversely

affect vehicle handling, and

lead to sudden tire failure. This

could result in loss of vehicle

control and potential injury.

7 38

Maintenance

Remove the valve cap from the tire

valve stem. Press the tire gage firm-

ly onto the valve to get a pressure

measurement. If the cold tire inflation

pressure matches the recommended

pressure on the tire and loading

information label, no further adjust-

ment is necessary. If the pressure is

low, add air until you reach the rec-

ommended amount.

Tire rotation

WARNING

To equalize tread wear, it is recom-

mended that the tires be rotated

every 7,500 miles (12,000 km) or

sooner if irregular wear develops.

• Inspect your tires frequently

for proper inflation as well as

wear and damage. Always use

a tire pressure gauge.

During rotation, check the tires for

correct balance.

• Tires with too much or too little

pressure wear unevenly caus-

ing poor handling, loss of vehi-

cle control, and sudden tire

failure leading to accidents,

injuries, and even death. The

recommended cold tire pres-

sure for your vehicle can be

found in this manual and on

the tire label located on the dri-

ver's side center pillar.

When rotating tires, check for uneven

wear and damage. Abnormal wear is

usually caused by incorrect tire pres-

sure, improper wheel alignment, out-

of-balance wheels, severe braking or

severe cornering. Look for bumps or

bulges in the tread or side of tire.

Replace the tire if you find either of

these conditions. Replace the tire if

fabric or cord is visible. After rotation,

be sure to bring the front and rear tire

pressures to specification and check

lug nut tightness.

If you overfill the tire, release air by

pushing on the metal stem in the

center of the tire valve. Recheck the

tire pressure with the tire gage. Be

sure to put the valve caps back on

the valve stems. They help prevent

leaks by keeping out dirt and mois-

ture.

• Worn tires can cause acci-

dents. Replace tires that are

worn, show uneven wear, or

are damaged.

Refer to “Tire and wheels” in section

8.

• Remember to check the pres-

sure of your spare tire.

HYUNDAI recommends that

you check the spare every

time you check the pressure

of the other tires on your vehi-

cle.

Directional tires (if equipped)

If you notice your vehicle vibrating

when driving on a smooth road, your

wheels may need to be rebalanced.

• Do not mix bias ply and radial

ply tires under any circum-

stances. This may cause

unusual handling characteris-

tics that could result in death,

severe injury, or property

damage.

CAUTION

Improper wheel weights can

damage your vehicle's alu-

WARNING - Replacing

tires

To reduce the chance or serious

or fatal injuries from an acci-

dent caused by tire failure or

loss of vehicle control:

• Using tires and wheel other

than the recommended sizes

could cause unusual handling

characteristics and poor vehi-

cle control, resulting in a seri-

ous accident.

• Replace tires that are worn,

show uneven wear, or are

damaged. Worn tires can

cause loss of braking effec-

tiveness, steering control, and

traction.

• Wheels that do not meet

HYUNDAI’s specifications may

fit poorly and result in damage

to the vehicle or unusual han-

dling and poor vehicle control.

Tire replacement

• The ABS works by comparing

the speed of the wheels. Tire

size can affect wheel speed.

When replacing tires, all 4

tires must use the same size

originally supplied with the

vehicle. Using tires of a differ-

ent size can cause the ABS

(Anti-lock Brake System) and

ESC (Electronic Stability

Control) to work irregularly (if

equipped).

• Do not drive your vehicle with

too little or too much pressure

in your tires. This can lead to

uneven wear and tire failure.

If the tire is worn evenly, a tread wear

indicator will appear as a solid band

across the tread. This shows there is

less than 1/16 inch (1.6 mm) of tread

left on the tire. Replace the tire when

this happens.

• When replacing tires, never

mix radial and bias-ply tires

on the same car. You must

replace all tires (including the

spare) if moving from radial to

bias-ply tires.

Do not wait for the band to appear

across the entire tread before replac-

ing the tire.

Tire traction

A compact spare tire has a shorter

tread life than a regular size tire.

Replace it when you can see the

tread wear indicator bars on the tire.

The replacement compact spare tire

should be the same size and design

WARNING - Tire age

Tires degrade over time, even

when they are not being used.

The chart below lists many of the dif-

ferent speed ratings currently being

used for passenger car tires. The

speed rating is part of the tire size

designation on the sidewall of the

tire. This symbol corresponds to that

tire's designed maximum safe oper-

ating speed.

Any tires that are over 6 years old,

based on the manufacturing date,

(including the spare tire) should be

replaced by new ones. You can find

the manufacturing date on the tire

sidewall (possibly on the inside of the

wheel), displaying the DOT Code.

The DOT Code is a series of num-

bers on a tire consisting of numbers

and English letters. The manufactur-

ing date is designated by the last four

digits (characters) of the DOT code.

Regardless of the remaining

tread, it is recommended that

tires generally be replaced after

six (6) years of normal service.

Heat caused by hot climates or

frequent high loading condi-

tions can accelerate the aging

process. Failure to follow this

warning can result in sudden

tire failure, which could lead to

a loss of control and an acci-

dent involving serious injury or

death.

to the Tire and Loading Information

label for recommended inflation

pressure.

Traction - AA, A, B & C

For example:

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 spec-

ified government test surfaces of

asphalt and concrete. A tire marked

C may have poor traction perform-

ance.

Tread wear

This number indicates the maximum

load in kilograms and pounds that

can be carried by the tire. When

replacing the tires on the vehicle,

always use a tire that has the same

load rating as the factory installed

tire.

The tread wear grade is a compara-

tive rating based on the wear rate of

the tire when tested under controlled

conditions on a specified govern-

ment test course. For example, a tire

graded 150 would wear one-and-a-

half times (1½) as well on the gov-

ernment course as a tire graded 100.

WARNING

The traction grade assigned to

this tire is based on straight-

ahead braking traction tests,

and does not include accelera-

tion, cornering, hydroplaning,

or peak traction characteristics.

The relative performance of tires

depends upon the actual conditions

of their use, however, and may

depart significantly from the norm

due to variations in driving habits,

service practices and differences in

road characteristics and climate.

These grades are molded on the

side-walls of passenger vehicle tires.

pounds per square inch (psi) or kilo-

pascal (kPa).

WARNING - Tire

temperature

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 condi-

tions on a specified indoor laboratory

test wheel.

The temperature grade for this

tire is established for a tire that

is properly inflated and not

overloaded. Excessive speed,

underinflation, or excessive

loading, either separately or in

combination, can cause heat

build-up and possible sudden

tire failure. This can cause loss

of vehicle control and serious

injury or death.

Accessory Weight: This means the

combined weight of optional acces-

sories. Some examples of optional

accessories are, automatic transaxle,

power seats, and air conditioning.

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 cor-

responds 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 labora-

tory test wheel than the minimum

required by law.

Aspect Ratio: The relationship of a

tire's height to its width.

Belt: A rubber coated layer of cords

that is located between the plies and

the tread. Cords may be made from

steel or other reinforcing materials.

Bead: The tire bead contains steel

wires wrapped by steel cords that

hold the tire onto the rim.

Bias Ply Tire: A pneumatic tire in

which the plies are laid at alternate

angles less than 90 degrees to the

centerline of the tread.

with snow tires.

Radial-ply tires

WARNING - Snow or ice

Radial-ply tires provide improved

tread life, road hazard resistance and

smoother high speed ride. The radi-

al-ply tires used on this vehicle are of

belted construction, and are selected

to complement the ride and handling

characteristics of your vehicle.

Radial-ply tires have the same load

carrying capacity, as bias-ply or bias

belted tires of the same size, and use

the same recommended inflation

pressure. Mixing of radial-ply tires

with bias-ply or bias belted tires is

not recommended. Any combina-

tions of radial-ply and bias-ply or bias

belted tires when used on the same

vehicle will seriously deteriorate

vehicle handling. The best rule to fol-

low is: Identical radial-ply tires should

always be used as a set of four.

• When driving on roads cov-

ered with snow or ice, drive at

less than 20 mph (30 km/h).

Tire chains

• Use the SAE “S” class or wire

chains.

Tire chains, if necessary, should be

installed on the drive wheels as fol-

lows.

• If you hear noise caused by

chains contacting the body,

retighten the chain to avoid

contact with the vehicle body.

2WD : Front wheels

AWD : All four wheels

If a full set of chains is not

available for a AWD vehicle,

chains may be installed on

the front wheels only.

• To prevent body damage,

retighten the chains after driv-

ing 0.3~0.6 miles (0.5~1.0 km).

• Do not use tire chains on

vehicles equipped with alu-

minum wheels. In unavoid-

able circumstance, use a wire

type chain.

Be sure that the chains are installed

in accordance with the manufactur-

er's instructions.

To minimize tire and chain wear, do

not continue to use tire chains when

they are no longer needed.

• Use wire chains less than 0.59

inches (15 mm) to prevent

damage to the chain’s con-

nection.

Longer wearing tires can be more

susceptible to irregular tread wear. It

is very important to follow the tire

rotation interval shown in this section

to achieve the tread life potential of

these tires. Cuts and punctures in

radial-ply tires are repairable only in

the tread area, because of sidewall

flexing. Consult your tire dealer for

radial-ply tire repairs.
