TIRES/WHEELS/LUG NUTS
Tires and wheels are very important and critical components
of the Mini Dumper. When specifying or replacing the
wheels, it is important that the wheels, tires, and axle are
properly matched.
TIRE WEAR
The tires (Figure 24) used on the Mini Dumper are
pnuematic. Proper inflation is 28 PSI (193 kPa). In addition,
inspect the tires for cuts, wear and deformity.

LUG NUT TORQUE REQUIREMENTS
It is extremely important to apply and maintain proper wheel
mounting torque on the TuffTruk. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts (Figure 25) in sequence.
DO NOT
torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table 6.
CAUTION
DO NOT
attempt to repair or modify a wheel. If the rim
is cracked, replace the rim immediately and inspect the
tire for cuts, wear, and deformations.
