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 (drive) and rear (steering) wheels on 2WD
machines are bolted directly to the wheel hub. Tighten
the front wheel bolts 90 ft-lbs (± 5 ft-lbs). Tighten the
rear wheel lug nuts to 90 ft-lbs (± 5 ft-lbs).
On 4WD machines, the rear (steering) wheels are
bolted to the wheel drive motors. Tighten the rear
wheel bolts to 90 ft-lbs (± 5 ft-lbs).
SERVICE
The front tires are inflated to 10 to 12 psi (69 to 83 kPa)
and the rear tires are inflated to 8 to 10 psi (55 to 69
kPa). These pressures provide 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).
NOTE:
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.
NOTE:
Commercial sealants can be injected through the
valve stem or directly into the tire.
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.
