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 calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

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.
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.
