WHEEL LUG NUT TORQUING
Proper installation requires that the wheel lug torque be set
to the recommended specification for your vehicle. These torque specifications
can be found in your vehicle’s shop manual or obtained from your vehicle
dealer. Finish tightening the lugs down with an accurate torque wrench. Use
a crisscross sequence (shown below) until they have reached their proper torque
value. Be careful because if you over torque a wheel, you can strip a lug nut,
stretch or break a wheel stud, and cause the wheel, brake rotor and/or brake
drum to distort.
NOTE: When installing new wheels you should re-torque
them after traveling the first 50 to 100 miles. This is necessary because as
the wheels are “breaking in” they may compress slightly allowing their
lugs to lose some of their torque. Simply repeat the same torque procedure listed
above.

NOTE
: Since the thickness of
an alloy wheel can differ from Original Equipment wheels, also verify that the
threads will be engaged by the lug nuts or bolts. Refer to the chart (above)
to determine the number of turns or the depth of engagement typical for your
stud or bolt size.
