Tire temperature and tire inflation pres-
sure are also increased while driving, de-
pending on the driving speed and the
tire load.
Tire inflation pressure changes by ap-
proximately 1.5 psi (0.1 bar) per 18 °F
(10 °C) of air temperature change. Keep
this in mind when checking tire inflation
pressure where the temperature is dif-
ferent from the outside temperature.
For example:
If the inside temperature is 68 °F
(20 °C) and the outside temperature is
32 °F (0 °C) then the cold tire inflation
pressure should be increased by 3 psi
(0.2 bar), which equals 1.5 psi (0.1 bar)
for every 18 °F (10 °C) for this outside
temperature condition.
Check tire inflation pressures more of-
ten if subject to a wide range of outdoor
temperatures, as tire pressures vary
with temperature changes.
Warning
G
Tire pressure may increase during opera-
tion.
Never reduce this normal pressure build
up or your tire pressure will be too low.
Underinflated tires wear excessively and/
or unevenly, adversely affect handling and
fuel economy, and are more likely to fail
from being overheated.
