NOTE

Trajectory area as shown applies

to all wheel/tire assemblies.

(1)

Take tire pressure reading on tire/wheel to

be changed and compare to Table 4-22. If

tire is underinflated or overinflated, or

there is obvious damage or suspected

damage to wheel or tire, completely deflate

tire before removing from trailer (Para 3-6).

(2)

Loosen ten lugnuts (1) but do not remove.

(3)

Position hydraulic jack under axle (2).

(4)

Using jack, raise axle (2) approximately 2 in.

until tire (3) just clears ground and position

jackstand under axle (2).

(5)

Lower jack until axle (2) rests on jackstand.

(6)

Remove ten lugnuts (1) from studs (4).

(7)

Using lifting device, remove tire (3) from

wheel hub (5).

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

and operating terrain is compared to Table 4-22, or 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 axle. Failure to follow these procedures may result

in serious personal injury or death.
