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.
