WARNING

Use caution when lifting or handling a wheel and tire assem-

bly. It is very heavy and could cause injury if improperly

lifted or if it should fall on you.

In case of a flat on any model, stop the truck where there will be no hazard to other

traffic or to the crew member changing the tire. Notify Organizational Maintenance

as soon as possible so the tire can be repaired and returned to service.

A spare wheel and tire assembly is provided on the M915 and M916 trucks. On these

models a tire hoist is provided to raise and lower the spare wheel and tire assembly

from the stowed position.

On models M917, M919 and M920, no spare is provided. Should you have a flat, use

one of the pusher axle wheel and tire assemblies as a spare.

If you have a flat on the rear of the M918, reduce speed as much as practical and re-

port to Organizational Maintenance as soon as possible. If you have a flat on one of

the front tires of the M918, exchange the flat tire with one of the outside rear duals.

When changing tires, do not substitute type or size tire unless all tires on the truck

can be converted. Keep all tires the same.
