286 TECHNICAL SPECIFICATIONS
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
Torque Patterns
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/bolts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
