Compact spare tire replacement

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
tire wheel is not designed for mount-
ing a regular size tire.

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.

(Continued)
• 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.

• 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.

• 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) (if equipped) to work
irregularly.

WARNING

A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance,

snow

chain clearance, speedometer
and odometer calibration, head-
light aim and bumper height.
