WHEELS AND TIRES
7C-5
SECTION 7C. TIRE SERVICE
GENERAL
The tires are subject to damage from sharp objects. If
large punctures or tears occur, take the tire (on the
wheel) to a qualified tire repair shop.
The front and rear tires are bolted to the wheel drive
motors. Tighten front wheel bolts to 55 ft-lbs (75 Nm)
and rear wheel bolts to 80 ft-lbs (108 Nm).
SERVICE
The tires are inflated to 14 psi (96 kPa). This pressure
provides the best results during average use.
When mounting a tire on the rim, inflate to 22 psi
(152 kPa) to ensure proper seating. After mounting,
reduce the tire pressure to the desired level for opera-
tion (Figure 7C-1).
1. Inject sealant through the valve stem or break one
bead loose and pull the tire past the rim flange.
2. Pour sealant into tire cavity.
3. Seat bead on the rim by inflating the tire to 22 psi
(152 kPa).
4. Rotate the tire slowly to spread the compound
inside the tire.
5. Reduce tire pressure to proper level.

WARNING
Compressed air can inflict serious injury. Use a
standoff gauge or tire cage when inflating tires. Know
the proper inflation rate before attempting to inflate
tires.
NOTICE
Never use grease or oil on the wheel rim when
mounting tires.
Mounting leaks around the tire bead can be repaired
using commercial sealants available at tire repair
shops. Apply the sealant using the procedure below.
