**Use only your authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil before
tightening.
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 halfway).
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.
