TIRES AND WHEELS

Tire care

WARNING

- Checking the tire inflation

pressure

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.

Inflate your tires consistent with

the instructions provided in this

manual.

Regularly check the tire infla-

tion pressure, and correct it as

needed: at least twice a month

and before a long trip.

Recommended cold tire infla-

tion pressures

OUB071018

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

1 mile (1.6 km).

If you fail to observe this pre-

caution, you may be driving on

tires with incorrect tire pres-

sures, a condition that may not

only compromise your vehicle's

driving stability, but also lead to

tire damage and the risk of an

accident.

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, top vehi-

cle handling, and minimum tire wear.

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 chapter 9.

8 40

Maintenance

• Underinflation also results in

excessive wear, poor handling and

reduced fuel economy. Wheel

deformation also is possible. Keep

your tire pressures at the proper

levels. If a tire frequently needs

refilling, have it checked by an

authorized Kia dealer.

Tire pressure

Checking tire inflation pres-

sure

Always observe the following:

Check your tires once a month or

more.

• 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 1

mile (1.6 km) since startup.)

Also, check the tire pressure of the

spare tire.

• Check the pressure of your spare

tire each time you check the pres-

sure of other tires.

• Overinflation produces a harsh

ride, excessive wear at the center

of the tire tread, and a greater pos-

careful not to overload a vehicle

luggage rack if your vehicle is

equipped with one.

• Warm tires normally exceed rec-

ommended cold tire pressures by 4

to 6 psi (28 to 41 kPa). Do not

release air from warm tires to

adjust the pressure or the tires will

be 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).

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.

• 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.

ommended amount.

proper inflation as well as wear and

damage. Always use a tire pres-

sure gauge.

To equalize tread wear, it is recom-

mended that the tires be rotated

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

sooner if irregular wear develops.

• Tires with too much or too little

pressure can cause tires to wear

unevenly, causing poor handling,

loss of vehicle control, and sudden

tire failure leading to accidents,

injuries, and even death. The rec-

ommended cold tire pressure for

your vehicle can be found in this

manual and on the tire label locat-

ed on the driver's side center pillar.

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 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 gauge. Be

sure to put the valve caps back on

the valve stems. They help prevent

leaks by keeping out dirt and mois-

ture.

• Remember to check the pressure

of your spare tire. Kia recommends

that you check the spare every

time you check the pressure of the

other tires on your vehicle.

Refer to “Tire and wheels” in chapter

9.

8 42

Maintenance

Without a spare tire

Disc brake pads should be inspected

for wear whenever tires are rotated.

Wheel alignment and tire bal-

ance

Rotate radial tires that have an

asymmetric tread pattern only from

front to rear and not from right to left.

The wheels on your vehicle were

aligned and balanced carefully at the

factory to give you the longest tire life

and best overall performance.

In most cases, you will not need to

have your wheels aligned again.

However, if you notice unusual tire

wear or your vehicle pulling one way

or the other, the alignment may need

to be reset.

WARNING - Mixing tires

• Do not use the compact spare

tire (if equipped) for tire rota-

tion.

S2BLA790A

Directional tires (if equipped)

• Do not mix bias ply and radial

ply tires under any circum-

stances. This may cause

unusual handling characteris-

tics.

If you notice your vehicle vibrating

when driving on a smooth road, your

wheels may need to be rebalanced.

CAUTION - Wheel weight

Improper wheel weights can

damage your vehicle's alu-

minum wheels. Use only

approved wheel weights.

NOTICE

•

We recommend that when replac-

ing tires, use the same which were

originally supplied with the vehi-

cle. If not, driving performance

could be altered.

It is best to replace all four tires at

the same time. If that is not possi-

ble, or necessary, then replace the

two front or two rear tires as a pair.

Replacing just one tire can serious-

ly affect your vehicle's handling.

tire wear. If you find a tire is worn

unevenly, have your dealer check the

wheel alignment.

This information identifies and

describes the fundamental charac-

teristics of the tire and also provides

TIN can be used to identify the tire in

case of a recall.

CAUTION - Wheel

Wheels that do not meet Kia's

specifications may fit poorly

and result in damage to the

vehicle or unusual handling and

poor vehicle control.

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.

WARNING - Tire age

Replace tires within the recom-

replace tires as recommended

can result in sudden tire failure,

which could lead to a loss of

control and an accident.

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.

This number is the greatest amount of

air pressure that should be put in the

tire. Do not exceed the maximum per-

missible inflation pressure. Refer to

the Tire and Loading Information label

for recommended inflation pressure.

Tread wear

Traction - AA, A, B & C

Tires degrade over time, even when

they are not being used. Regardless

of the remaining tread, we recom-

mend that tires be replaced after

approximately six (6) years of normal

service. Heat caused by hot climates

or frequent high loading conditions

can accelerate the aging process.

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.

The traction grades, from highest to

lowest, are AA, A, B and C. Those

grades represent the tires 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.

These grades are molded on the

side-walls of passenger vehicle tires.

The tires available as standard or

optional equipment on your vehicles

may vary with respect to grade.

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.

The traction grade assigned to this

tire is based on straight-ahead brak-

ing traction tests, and does not

include acceleration, cornering,

hydroplaning, or peak traction char-

acteristics.

Maintenance

Temperature -A, B & C

Tire terminology and definitions

Cold Tire Pressure: The amount of

air pressure in a tire, measured in

kilopascals (kPa) or pounds per

square inch (psi) before a tire has

built up heat from driving.

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.

Air Pressure: The amount of air

inside the tire pressing outward on

the tire. Air pressure is expressed in

kilopascal (kPa) or pounds per

square inch (psi).

Curb Weight: This means the weight

of a motor vehicle with standard and

optional equipment including the

maximum capacity of fuel, oil and

coolant, but without passengers and

cargo.

Accessory Weight: This means the

combined weight of optional acces-

sories. Some examples of optional

accessories are, intelligent variable

transmission, 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.

DOT Markings: A code molded into

the sidewall of a tire signifying that

the tire is in compliance with the U.S.

Department of Transportation motor

vehicle safety standards. The DOT

code includes the Tire Identification

Number (TIN), an alphanumeric des-

ignator which can also identify the

tire manufacturer, production plant,

brand and date of production.

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.

Maintenance

All season tires

Snow tires

WARNING

Kia specifies all season tires on

some models to provide good per-

formance for use all year round,

including snowy and icy road condi-

tions. All season tires are identified

by ALL SEASON and/or M+S (Mud

and Snow) on the tire sidewall. Snow

tires have better snow traction than

all season tires and may be more

appropriate in some areas.

If 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.

Do not use summer tires at tem-

peratures below 45°F (7°C) or

when driving on snow or ice. At

temperatures below 45°F (7°C),

summer tires can lose elastici-

ty, and therefore traction and

braking power as well. Change

the tires on your vehicle to win-

ter or all-weather tires of the

same size as the standard tires

of the vehicle. Both types of

tires are identified by the M+S

(Mud and Snow) marking. Using

summer tires at very cold tem-

peratures could cause cracks to

form, thereby damaging the

tires permanently.

Snow tires should carry 4 psi (28

kPa) more air pressure than the

pressure recommended for the stan-

dard tires on the tire label on the dri-

ver's side of the center pillar, or up to

the maximum pressure shown on the

tire sidewall, whichever is less.

Summer tires

Kia specifies summer tires on some

models to provide superior perform-

ance on dry roads. Summer tire per-

formance is substantially reduced in

snow and ice. Summer tires do not

have the tire traction rating M+S

(Mud and Snow) on the tire side wall.

If you plan to operate your vehicle in

snowy or icy conditions, Kia recom-

mends the use of snow tires or all

season tires on all four wheels.

Do not drive faster than 75 mph (120

km/h) when your vehicle is equipped

with snow tires.

8 52

Maintenance

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.

Tire chains

Radial-ply tires

Tire chains, if necessary, should be 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 select-

ed to complement the ride and han-

dling characteristics of your vehicle.

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.

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 covered

with snow or ice, drive at less than

20 mph (30 km/h).

• Use the SAE “S” class or wire

chains.

• If you hear noise caused by chains

contacting the body, retighten the

chain to avoid contact with the

vehicle body.

• To prevent body damage, retighten

the chains after driving 0.3~0.6

miles (0.5~1.0 km).

• Do not use tire chains on vehicles

equipped with aluminum wheels.

In unavoidable circumstances, use

a wire type chain.

• Use wire chains less than 0.47

inches (12 mm) in width to prevent

damage to the chain’s connection.

8 53

Maintenance

• It is not easy to recognize the tire

damage with your own eyes. In the

event that the tire is impacted, have

the tire checked or replaced

because the tire damage may

cause air leakage from the tire.

Low aspect ratio tire

(if equipped)

CAUTION

Because the sidewall of a low

aspect ratio tire is shorter than

normal, the wheel and tire of a

low aspect ratio tire is more eas-

ily damaged. Therefore, follow

the instructions below.

Low aspect ratio tires, whose aspect

ratio is lower than 50, are provided

for sporty looks.

Because the low aspect ratio tires

are optimized for handling and brak-

ing, they may be more uncomfortable

to ride in and more noisy when com-

pared with normal tires.

• If the tire is damaged by driving on

a rough road, off road, pothole,

manhole, or curb stone, the dam-

age will not be covered by the war-

ranty.

• When driving on a rough road

or off road, drive cautiously

because the tires and wheels

may become damaged. And

after driving, inspect the tires

and wheels.

• You can find out tire information on

the tire sidewall.

• 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 impacted, we rec-

ommend that you inspect the

tire condition or contact an

authorized Kia dealer.

• To prevent damage to the tire,

inspect the tire condition and

pressure every 1,900 miles

(3,000 km).
