Maintenance

TIRES AND WHEELS

Tire Care

• Replace tires that are worn,

show uneven wear, or are dam-

aged. Worn tires can cause

loss of braking effectiveness,

steering) control, or traction.

• ALWAYS replace tires with the

same size as each tire that

was originally supplied with

this vehicle. Using tires and

wheels other than the recom-

mended sizes could cause

unusual handling characteris-

tics, poor vehicle control, or

negatively affect your vehi-

cle's Anti-Lock Brake System

(ABS) resulting in a serious

accident.

WARNING

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.

Tire failure may cause loss of

vehicle control resulting in an

accident. To reduce risk of

SERIOUS INJURY or DEATH,

take the following precautions:

• Inspect your tires monthly for

proper inflation as well as

wear and damage.

• The recommended cold tire

pressure for your vehicle can

be found in this manual and on

the tire label located on the dri-

ver's side center pillar. Always

use a tire pressure gauge to

measure tire pressure. Tires

with too much or too little

pressure wear unevenly caus-

ing poor handling.

OTLE085006

• Check the pressure of the

spare every time you check

the pressure of the other tires

on your vehicle.

All specifications (sizes and pres-

sures) can be found on a label

attached to the driver's side center

pillar.

Recommended Cold Tire

Inflation Pressures

WARNING

CAUTION

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 for less

than one mile (1.6 km).

Warm tires normally exceed recom-

mended cold tire pressures 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-inflat-

ed. For recommended inflation pres-

sure, refer to "Tire and Wheels" in

chapter 8.

Recommended pressures must

be maintained for the best ride,

vehicle handling, and minimum

tire wear.

Over-inflation or under-inflation

can reduce tire life, adversely

affect vehicle handling, and

lead to sudden tire failure that

could result in loss of vehicle

control resulting in an accident.

Severe under-inflation can lead

to severe heat build-up, causing

blowouts, tread separation and

other tire failures that can result

in the loss of vehicle control

resulting in an accident. This

risk is much higher on hot days

and when driving for long peri-

ods at high speeds.

• Under-inflation results in

excessive wear, poor handling

and reduced fuel economy.

Wheel deformation is also

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.

• Over-inflation produces

a

harsh ride, excessive wear at

the center of the tire tread,

and a greater possibility of

damage from road hazards.

7

7-37

Maintenance

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 gauge. Be

sure to put the valve caps back on

the valve stems. 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 Tire Inflation Pressure

Check your tires, including the spare

tire, once a month or more.

Tire Rotation

To equalize tread wear, HYUNDAI

recommends that the tires be rotated

according to the maintenance sched-

ule or sooner if irregular wear devel-

ops.

During rotation, check the tires for

correct balance.

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 the tire.

Replace the tire if you find any 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 (proper torque is

79~94 lbf·ft [11~13 kgf·m]).

How to check

Use a good quality tire pressure

gauge to check tire pressure. You

can not tell if your tires are properly

inflated simply by looking at them.

Radial tires may look properly inflat-

ed when they are under-inflated.

Remove the valve cap from the tire

valve stem. Press the tire gauge firm-

ly onto the valve to get a pressure

measurement. If the cold tire inflation

pressure matches the recommended

pressure on the tire label located on

the driver's side center pillar or in this

manual. No further adjustment is

necessary. If the pressure is low, add

air until you reach the recommended

pressure. Make sure to put the valve

caps back on the valve stems.

Without the valve cap, dirt or mois-

ture could get into the valve core and

cause air leakage. If a valve cap is

missing, install a new one as soon as

possible.

or the other, the alignment may need

to be reset.

If you notice your vehicle vibrating

when driving on a smooth road, your

wheels may need to be rebalanced.

ODH073802

Disc brake pads should be inspected

for wear whenever tires are rotated.

WARNING

• Do not use the compact spare

tire for tire rotation.

NOTICE

• Do not mix bias ply and radial

ply tires under any circum-

stances. This may cause

unusual handling characteris-

tics that may cause loss of

vehicle control resulting in an

accident.

Improper wheel weights can dam-

age your vehicle’s aluminum

wheels. Use only approved wheel

weights.

7-39

Maintenance

Tire Replacement

• When replacing tires (or

wheels), it is recommended to

replace the two front or two

rear tires (or wheels) as a pair.

Replacing just one tire can

seriously affect your vehicle's

handling.

• Tires degrade over time, even

when they are not being used.

Regardless of the remaining

tread, HYUNDAI recommends

that tires 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 may cause sudden

tire failure, which could lead to

a loss of vehicle control result-

ing in an accident.

WARNING

Tread wear indicator

To reduce the risk of DEATH or

SERIOUS INJURY:

• Replace tires that are worn,

show uneven wear, or are

damaged. Worn tires can

cause loss of braking effec-

tiveness, steering control, and

traction.

• Always replace tires with the

same size as each tire that

was originally supplied with

this vehicle. Using tires and

wheels other than the recom-

mended sizes could cause

unusual handling characteris-

tics, poor vehicle control, or

negatively affect your vehi-

cle’s Anti-Lock Brake System

(ABS) resulting in a serious

accident.

OLMB073027

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.

Do not wait for the band to appear

across the entire tread before replac-

ing the tire.

Compact spare tire replacement

Wheel Replacement

Tire Maintenance

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

tire as the one provided with your

new vehicle and should be mounted

on the same compact spare tire

wheel. The compact spare tire is not

designed to be mounted on a regular

size wheel, and the compact spare

wheel alignment.

When you have new tires installed,

make sure they are balanced. This

will increase vehicle ride comfort and

tire life. Additionally, a tire should

always be rebalanced if it is removed

from the wheel.

Tire Traction

Tire traction can be reduced if you

drive on worn tires, tires that are

improperly inflated or on slippery

road surfaces. Tires should be

replaced when the tread depth is at

least 2/32 inch (1.6 mm). To reduce

the possibility of losing control, slow

down whenever there is rain, snow or

ice on the road.

Tire Sidewall Labeling

This information identifies and

describes the fundamental charac-

teristics 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.

WARNING

The original tire should be

repaired or replaced as soon as

possible to avoid failure of the

spare and loss of vehicle con-

trol resulting in an accident.The

compact spare tire is for emer-

gency use only. Do not operate

your vehicle over 50 mph (80

km/h) when using the compact

spare tire.

WARNING

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,

under-inflation, over-inflation,

or excessive loading, either

separately or in combination,

can cause heat build-up and

possible sudden tire failure.

This may cause loss of vehicle

control resulting in an accident.

Sustained high temperature can

cause the material of the tire to

degenerate and reduce tire life, and

excessive temperature can lead to

the sidewall of the tire.

Summer Tires

HYUNDAI specifies summer tires on

some models to provide superior

performance on dry roads. Summer

tire performance is substantially

reduced in snow and ice. Summer

tires do not have the tire traction rat-

Maintenance

Low Aspect Ratio Tires

Low aspect ratio tires, the aspect

ratio is lower than 50, are provided

for sporty looks.

Because low aspect ratio tires are

optimized for handling and braking,

their sidewall is a little stiffer than a

standard tire. Also low aspect ratio

tires tend to be wider and conse-

quently have a greater contact patch

with the road surface. In some

instances they may generate more

road noise compared with standard

tires.

CAUTION

Because the sidewall of a low

aspect ratio tire is shorter than

a standard tire, the rim of the

wheel and the tire itself is more

easily susceptible to damage.

Use caution when driving and

follow the guidelines below to

help minimize damage to the

wheel and tire:

- When driving on a rough road

or off road, drive cautiously

because tires and wheels may

be damaged. And after driving,

inspect tires and wheels.

• It is not easy to recognize tire

damage with your own eyes.

But if there is the slightest

hint of tire damage, have the

tire checked or replaced

because the tire damage may

cause air leakage from the

tire.

• If the tire is damaged by driv-

ing on a rough road, off road,

pothole, manhole, or curb

stone, it will not be covered by

the warranty.

- When passing over a pothole,

speed bump, manhole, or curb

stone, drive slowly so that the

tires and wheels are not dam-

aged.

- If the tire is subjected to a

severe impact, have the tire

and wheel inspected by an

authorized HYUNDAI dealer.

- Inspect the tire condition and

pressure every 1,800 miles

(3,000km).
