To properly install the wheel lugs, the torque must be set to the recommended specification for your vehicle. These specifications can be found in your vehicle’s shop manual or obtained from your vehicle dealer. All hubs should also be clean and free from debris and checked regularly.
Using an accurate torque wrench, tighten the lugs by using a crisscross sequence as shown below until they have reached their proper torque value.

NOTE: Over tightening can cause the following.

(1) Striped lug nut
(2) Stretched wheel stud
(3) Broken wheel stud
(4) Distorted brake rotor and/or brake drum.

 After installing new wheels they should re-torqued after the first 80 to 160 kilometers. This is necessary as wheels may compress slightly allowing their lugs to loosen some of their torque.

Once this has been done please double check the wheel lugs every time 6 months to ensure safety, this should be done in line with your normal vehicle safety checks too.

: Since the thickness of an alloy wheel can differ from Original Equipment wheels, you should verify the amount of threads 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.
