Tire inflation pressure
6
Set the correct tire pressure before
loading the vehicle. If the vehicle has
been loaded, check the tire pressures
and correct them if necessary.
The tires can be considered cold if the
vehicle has been parked for at least
3 hours or driven less than 1 mile
(1.6 km) at an ambient temperature of
approximately 68 °F (20 °C).
Keeping the tires properly inflated pro-
vides the best handling, tread life and
riding comfort.
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 inflation pressures
vary with temperature changes.
! CAUTION
The pressure difference between the
tires on a single axle should not ex-
ceed 1.5 psi (10 kPa).
