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 and add
two drops of oil at the interface between the hex and the
washer.
Do not oil wheel studs. For chrome wheels, do not
substitute with chrome plated wheel nuts.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
