TIRES AND WHEELS

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must al‐
ways maintain recommended tire infla‐ tion pressures and stay within the load
limits and weight distribution recom‐
mended for your vehicle.
Recommended cold tire inflation
pressures
All tire pressures (including the spare)
should be checked when the tires are cold. L

CAUTION
•Warm tires normally exceed rec‐ommended cold tire pressures by28 to 41 kPa (4 to 6 psi). Do notrelease air from warm tires to ad‐just the pressure or the tires willbe underinflated.
•Be sure to reinstall the tire infla‐tion valve caps. Without the valvecap, dirt or moisture could get intothe valve core and cause air leak‐age. If a valve cap is missing, in‐stall a new one as soon as possi‐ble.
WARNING
nTire inflation
Overinflation or underinflation canreduce tire life, adversely affect ve‐hicle handling, and lead to suddentire failure. This could result in lossof vehicle control and potential in‐jury.
CAUTION
nTire pressure
Always observe the following:•Check tire pressure when the tiresare cold. (After vehicle has beenparked for at least three hours orhasn't been driven more than1.6 km (one mile) since startup.)
•Check the pressure of your sparetire each time you check the pres‐sure of other tires.
•Never overload your vehicle. Becareful not to overload a vehicleluggage rack if your vehicle isequipped with one.
•Worn, old tires can cause acci‐dents. If your tread is badly worn,or if your tires have been dam‐aged, replace them.
Checking tire inflation pressure
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 can not tell if your tires are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they're underinfla‐ ted.
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
1.6 km (one mile).
Remove the valve cap from the tire
valve stem. Press the tire gauge firmly onto the valve to get a pressure meas‐
urement. If the cold tire inflation pres‐
sure matches the recommended pres‐ sure on the tire and loading information
label, no further adjustment is necessa‐
ry. 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 cen‐
ter 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 moisture.

WARNING
•Inspect your tires frequently forproper inflation as well as wearand damage. Always use a tirepressure gauge.
•Tires with too much or too littlepressure wear unevenly causingpoor handling, loss of vehicle con‐trol, and sudden tire failure leadingto accidents, injuries, and evendeath. The recommended cold tirepressure for your vehicle can befound in this manual and on thetire label located on the driver'sside center pillar.
•Worn tires can cause accidents.Replace tires that are worn, showuneven wear, or are damaged.
•Remember to check the pressureof your spare tire. Kia recom‐mends that you check the spareevery time you check the pressureof the other tires on your vehicle.
Tire rotation
To equalize tread wear, it is recommen‐
ded that the tires be rotated every 12,000 km (7,500 miles) or sooner if ir‐
regular wear develops. During rotation, check the tires for cor‐
rect 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 tire. Re‐ place 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 tight‐
ness.
Refer to L

NOTICE
We recommend that when replacing
tires, use the same originally sup‐
plied with the vehicles.
If not, that affects driving perform‐
ance.
CAUTION
When replacing the tires, recheckand tighten the wheel nuts afterdriving about 50 km (31 miles) andrecheck after driving about 1,000 km(620 miles).If the steering wheel shakes or thevehicle vibrates while driving, thetire is out of balance. Align the tirebalance. If the problem is not solved,we recommend that you contact anauthorized Kia dealer.
WARNING

(Continued)
(Continued)
To reduce the chance of serious orfatal injuries from an accidentcaused by tire failure or loss of vehi‐cle control:•Replace tires that are worn, showuneven wear, or are damaged.Worn tires can cause loss of brak‐ing effectiveness, steering control,and traction.
•Do not drive your vehicle with toolittle or too much pressure in yourtires. This can lead to uneven wearand tire failure.
•When replacing tires, never mix ra‐dial and bias-ply tires on the samecar. You must replace all tires (in‐cluding the spare) if moving fromradial to bias-ply tires.
•Using tires and wheels other thanthe recommended sizes couldcause unusual handling character‐istics and poor vehicle control, re‐sulting in a serious accident.
(Continued)
(Continued)
•Wheels that do not meet Kia’sspecifications may fit poorly andresult in damage to the vehicle orunusual handling and poor vehiclecontrol.
•The ABS works by comparing thespeed of the wheels. The tire sizeaffects wheel speed. When replac‐ing tires, all 4 tires must use thesame size originally supplied withthe vehicle. Using tires of a differ‐ent size can cause the ABS (Anti-lock Brake System) and ESC (Elec‐tronic Stability Control) to work ir‐regularly.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new wheels are equivalent to the original factory
units in diameter, rim width and offset.
WARNING
A wheel that is not the correct sizemay adversely affect wheel and

NOTICE
•We recommend that when replacing tires, use the same originally supplied with the vehicles.
If not, that affects driving performance.
•When driving in high altitude grades, it is natural for the atmospheric pressure to decrease.
Therefore, please check the tire pressure and add more air when necessary.
Additionally required tire air pressure per km above sea level: 1.5 psi/km
