3-5. SPARE TIRE REPLACEMENT (CONT).

If tire has been run flat, or is overinflated or underinflated when tire pressure measured is

compared to Table 3-4, or if wheel/tire assembly has obvious or suspected damage, it is not

safe to adjust tire pressure. Completely deflate tire according to Para 3-6, and remove the

tire from the trailer. Failure to follow these procedures may result in serious personal injury

or death.

NOTE

Air wrench from PLS truck may be used in place of sliding handle and extension wrench.

Trajectory area as shown applies to all wheel/tire assemblies.

Table 3-4. Unsafe Inflation Pressure

SPARE TIRE IS:

Overinflated.

Underinflated.

Tire pressure measured is 25% or

Tire pressure measured is 80% or

more above standard pressure.

less than the standard tire

pressure.

Do not adjust pressure if above

Do not adjust pressure if below

pressure shown below.

Spare Tire Pressure

109 psi (752 kPa)

70 psi (483 kPa)

(1)

Take tire pressure reading on spare tire and compare reading to Table 3-4. If tire is overinflated or

underinflated, or there is obvious damage or suspected damage to tire or wheel components, completely

deflate tire (Para 3-6) and stand out of trajectory range before lowering tire from trailer.

(2)

Remove slide handle, extension wrench and socket from stowage box (1).

(3)

Ensure handle (2) is in LOCKED position.
