Table 4-16. Cold Tire Air Pressure

TM 9-2330-385-14

While changing tires or while performing tire maintenance, stay out of the trajectory as shown by the

area indicated. Failure to follow proper procedures may result in injury or death to personnel.

Under some circumstances, the trajectory may deviate from its expected path. Failure to follow proper

procedures may result in injury or death to personnel.

If the tire is underinflated or overinflated, or there is obvious or suspected damage on the tire or wheel

components, the tire must be completely deflated (Para 3-6). To deflate the tire, remove the valve core from the

valve stem and stand out of the trajectory area before the wheel is removed from the trailer or personal injury may

result.

The wheel/tire must be inflated in a safety cage or personal injury or death may result.

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

compared to Table 4-15, 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 axle. Failure to follow these

procedures may result in serious personal injury or death.

Tire air pressure must be checked properly or serious injury or death may result.
