WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening. 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 and add two drops
of oil at the interface between the lug nut/bolt and the
washer. Do not oil wheel studs.
Two-Piece Lug Nut
594 TECHNICAL SPECIFICATIONS

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half-
way).
After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.Wheel Mounting Surface
