Tire Maintenance; Checking Inflation - IC Bus CE Series Operation And Maintenance Manual

To prevent property damage, personal injury, and
/ or death:
• 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.
To prevent property damage, personal injury,
and / or death, 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.
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. All drive tires should be within a 5 psi
pressure range. Tag or pusher axle tires on the same axle should
be within a 5 psi (34 kPa) pressure range.
To minimize rim corrosion, it is particularly important to keep
moisture from the inside of tires and proper selection of air
compressor equipment, proper air line routing, and the use of
