Torque specs for wheels

Does anyone know how many pounds of torque are recommended when tightening the bolts on the wheels of a 3.0i BMW z4?
Thanks.

Garage List
110N*m to 130N*m

TIS calls out 120N*m plus or minus 10N*m. That's 81ft/Lbs to 96ft/Lbs. Most 1/2 inch drive clicker-type torque wrenches aren't that accurate anyway so pick your number somewhere in the range.

Always tighten when wheels, etc are cool. Never when hot.

Dammits reply was clearly the most helpful. Seriously what value does that add?


Just piling on, I keep my wheel torque wrench at 85lbs, and also remember to tighten them in a star pattern to help avoid them loosening over time. More force is NOT always better, as you can be damaging the lug or its seat in the wheel if you over-tighten it. If you do that, they are eventually going to work loose anyway. Or the worst case scenario, which is shearing off a lug.

I would presume that the torque spec is for dry (no oil) threads. Since the whole purpose of torque is to tension the stud, wet (oily) threads can result in as much as 40% more tension than dry. Depending on the design factor, this may cause the bolt to fail in shear when tightening.

If your bolts are rusty, it is ok to clean them up with some oil - just make sure you dry the threads before tightening.

Bad idea to keep your torque wrench at 85lbs constantly. You want to set it back to 0 after you use it, or the torque wrench will fail prematurely.
