and the tire load, the tire temperature
changes. When the tire temperature
changes by 18¦ (10¥), the tire inflation
pressure will change by approximately
10 kpa (0.1 bar, 1.5 psi). Keep this in mind
when checking tire inflation pressure on
warm tires and adjust the tire pressure
only if the tire inflation pressure is too
low for the current operating conditions.
If you check the tire inflation pressure
when the tires are warm, the reading will
be higher than the cold reading. This is
normal. Do not let air out to match the
specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver's door
B‑pillar.
Keeping the tires properly inflated pro-
vides the best handling, tread life and rid-
ing comfort.
In addition to the Tire and Loading Infor-
mation placard on the driver's door B‑pil-
lar, also consult the tire inflation pres-
sure label (if available) on the inside of
the filler flap for any additional informa-
tion pertaining to special driving situa-
tions. For more information, see "Impor-
tant notes on tire inflation pressure"
( page 126).

apply to the tires installed as original
equipment.
Important notes on tire inflation pres-
sure
G WARNING
If the tire inflation pressure drops repeat-
edly, check the tires for punctures from
foreign objects and/or whether air is leak-
ing from the valves or from around the rim.
Tire temperature and tire inflation pres-
sure are also increased while driving,
depending on the driving speed and the
tire load.
Potential problems associated with
underinflated and overinflated tires
Underinflated tires
G WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ-
omy, and are more likely to fail from being
overheated.
