•
Inspect slack adjuster boots, if equipped,
for cuts or tears.
•
Inspect anchor straps, if equipped, for
damage.
•
Look for worn clevis pins on brake cham-
ber pushrods.
•
Look for missing or damaged cotter pins
on the clevis pins.
•
Ensure chamber piston rods are in line
with the slack adjusters.

1. Inspect each tire for the following:
•
valve stem caps on every tire, screwed on
finger-tight
•
bulges, cracks, cuts, and penetrations
•
oil contamination (petroleum derivatives will
soften the rubber and destroy the tire)
•
tread depth—if tread is less than 4/32 inch
(3 mm) on any front tire, or less than 2/32
inch (1.5 mm) on any rear tire, replace the
tire
•
debris lodged between duel tire sets
2. Check tire inflation.
For inflation pressures and maximum loads, see
the tire manufacturer's guidelines. Inflate the tires
to the applicable pressures if needed.
If a tire has been run flat or under-inflated, check
the wheel and tire for damage before adding air.
Keep compressed air reservoirs and lines dry
during tire inflation. Use well-maintained inline
moisture traps and service them regularly.
WARNING
Do not operate the vehicle with underinflated or
overinflated tires. Incorrect inflation can stress
the tires and make the tires and rims more sus-
ceptible to damage, possibly leading to rim or
tire failure and loss of vehicle control, resulting
in serious personal injury or death.
NOTICE
A weekly pressure loss of 4 psi (28 kPa) or more
in a tire may indicate damage. The tire should be
inspected and, if necessary, repaired or replaced
by a qualified tire service facility.
IMPORTANT: The load and cold inflation pres-
sure must not exceed the rim or wheel manu-
facturer's recommendations, even though the
tire may be approved for a higher load inflation.
Consult the rim or wheel manufacturer for the
correct tire inflation pressure for the vehicle
load.
3. Examine each rim and wheel component.
