tire inflation range stated on the tire
sidewall and the tire manufacturer s tire
load-pressure charts.
Checking Inflation
Check the tires daily and always before
long-distance trips
Follow the tire manufacturer s
recommended cold inflation pressure for
the tire size, type, load range (ply
rating), and axle loading typical for
your operation. Each steer axle tire load
will equal one-half the steer axle
loading; each drive tire load will be
one-quarter the axle loading, if fitted
with four tires.
Always check the inflation pressure
when the tires are cold. Never bleed air
from hot tires to relieve normal
pressure buildup. Normal increases in
pressure during operation will be 69 to
103 kPa (10 to 15 psi), which is allowable
in truck tires. Tires on the same axle
should have the same air pressure as
the corresponding other tire(s) on that
axle. All tires on the steering axle
should be within 21 kPa (3 psi) of each
other. All drive axle tires should be
within 34 kPa (5 psi) of each other.
To minimize rim corrosion, it is
important to keep moisture from the
inside of tires and proper selection of
air compressor equipment, proper air
line routing, and the use of shop air
dryers is strongly recommended to
prevent moisture in the high-pressure
air used for tire inflation.
Warning
Reducing the tire pressure will
improve ride and handling in lightly
loaded vehicle conditions. It is
important to increase the tire
pressure as the load increases to
avoid tire overheating and tire
damage.
