NOTE

When changing tires, do not substitute type or size of tire

unless all tires on the vehicle can be converted. Keep all

tires the same.

TIRE INFLATION

Checking tire air pressure is an important aspect of tire maintenance. Tire air pressure

must be checked weekly. Recommended air pressures for all tires on all vehicle models

have been carefully selected to provide maximum tire life and performance. Refer to

Equipment Data in WP 0003 for proper tire air pressure application. Check and adjust

tire air pressure when tires are cold. Recommended air pressures are speciﬁed for cold

tires (i.e., tires that have not warmed up due to vehicle operation). When vehicle is

operated and tire warms up, tire air pressure increases. Do not decrease warm tire air

pressure to recommended air pressure for a cold tire. Following cross-country

operations in mud, sand, or snow, ensure that tires are inﬂated for highway use.

WARNING

Stay clear of wheel when checking tire air pressure and

inﬂating tire. Injury or death to personnel may result from

exploding wheel components. Seek medical attention in the

event of an injury.

1. Remove tire air pressure gauge from tool box.

2. Remove tire valve stem cap.

3. Check tire air pressure. Refer to Equipment Data in WP 0003 for proper tire air

pressure application.

4. If necessary, remove air hose from tool box and use quick disconnect coupling

provided at air reservoir as indicated in (Figure 1, Item 1), (Figure 2, Item 1), and

(Figure 3, Item 1) to put air in tires.

5. Install tire valve stem cap and tighten ﬁnger tight.

6. Store tire air pressure gauge and air hose in tool box.
