TECHNICAL SPECIFICATIONS
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
NOTE:
Dual wheels are flat mounted, center piloted. The
lug nuts are a two-piece assembly. When the tires
are being rotated or replaced, clean these lug nuts
at the interface between the lug nut/bolt and the
washer. Do not oil wheel studs.
Two-Piece Lug Nut
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface
Retighten the wheel nuts in the same sequence to
the torques listed in the table. Go through the
sequence a second time to verify that specific
torque has been achieved. Retighten to
specifications after 25 miles (40 km) and check
the lug nut/bolt torque to be sure that all the lug
nuts/bolts are properly tightened.
8/10 Lug Nuts/Bolts Torque Patterns
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval.
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels becoming
elongated. This is especially important during the
first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to
recommended torque. Tighten the wheel nuts to
1 — 10 Bolt Pattern
2 — 8 Bolt Pattern
