Maintenance Instructions
WARNING
To prevent personal injury and / or death, or
property damage:
• Do not mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners. Mixing wheel
types may cause premature wheel failure.
• Do not change from steel wheels or a steel
inner and aluminum outer wheel combination
to aluminum wheels without changing the
mounting hardware since the thicker aluminum
wheels require longer studs.
In some cases
with flange nut mounting systems, changing
the hub and stud assembly may be required.
Improperly mixing components could cause
wheel or fastener failures.
• Do not mix foreign (not made in North America)
wheel mounting parts with domestic (made
in North America) parts.
Many foreign wheel
components look similar to, but are not exactly
the same as, domestic made components.
Mixing components can cause wheel or fastener
failures.
WARNING
To prevent personal injury and / or death, or
property damage, do not mount tube-type tires
on tubeless wheels or tubeless tires on tube-type
wheels.
Tire Maintenance
Preserving proper inflation pressure is a very important
maintenance practice to ensure safe vehicle operation and long
life for the tires.
Failure to maintain correct inflation pressure may result in
sudden tire destruction, improper vehicle handling, and may
cause rapid and irregular tire wear.
Therefore, inflation
pressures should be checked 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 1/2 steer axle loading. Each drive tire load will be 1/4 the
axle loading, if fitted with four tires.)
Checking Inflation
Always check inflation pressure when tires are cold. Never bleed
air from hot tires to relieve normal pressure buildup. Normal
increases in pressure during operation will be 10 to 15 psi (69
to 103 kPa), 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. Steer tires should be within a 3 psi
(21 kPa) pressure range of each other. All drive tires should be
within a 5 psi pressure range of each other. Tag or pusher axle
tires on the same axle should be within a 5 psi (34 kPa) pressure
range of each other.
