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. Cold Tires means the vehicle has
not been driven for at least three hours
or driven less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi‐
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to Tires and wheels on page
9-11.
OJF085012
All specifications (sizes and pressures)
can be found on a label attached to the
vehicle.
WARNING
n Tire underinflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to severe
heat build-up, causing blowouts,
tread separation and other tire fail‐
ures that can result in the loss of ve‐
hicle control leading to severe injury
or death. This risk is much higher on

hot days and when driving for long
periods at high speeds.
CAUTION
• Underinflation also results in ex‐
cessive wear, poor handling and
reduced fuel economy. Wheel de‐
formation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, we recommend that the
system be checked by an author‐
ized Kia dealer.
• Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.
