2018 Ram 4500 Chassis Cab flat tire

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 hex and the washer.
Ensure that the socket is fully engaged on the lug nut/bolt
(do not insert it half way).
Do not oil wheel studs. For chrome wheels, do not substi-
tute with chrome plated wheel nuts. 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 seated against the wheel.
