What is the torque spec for aluminum wheels?
Aluminum wheels should have the lug nuts torqued to 70 ft. lbs. The beadlocks should be 20-22 ft. lbs.
What is the torque for 1/2 inch lug nuts?
For a 1/2-inch lug the torque spec ranges from 75- to 85-ft-lbs.
Is there a tightening pattern when tightening the lug nuts?
Tightening them in a cross pattern reduces the likelihood of things shifting and flexing, which means that your lugs will stay tight after you torque them. Using the above diagram, tighten your lug nuts in the correct order that corresponds with the number of lug bolts your wheel has.
How many ft lbs should lug nuts be?
A quick glance at a lug nut torque chart shows that most lug nuts should be torqued between 80 and 100 ft-lbs. Some require less torque, others more.

What happens if you over torque lug nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud .
What size drive torque wrench for lug nuts?
Like any other ratchet wrench, the longer the handle and the bigger the drive, the more torque it can deliver. A click-style torque wrench with a 1/2-inch drive is optimal for lug nuts and good for most other automotive applications.
How do you measure torque on lug nuts?
Attach each lug nut by hand, and then use a manual torque wrench to tighten until you hear the ‘click’ sound that indicates you’ve reached the right amount of torque. The number—usually in the 75-100 lb-ft range—should be easy to locate in your vehicle’s owner’s manual.
What is the torque for a 13/16 lug nut?
just about any steel wheel lug nut is a minimum of 85 lb. -ft . This includes a good majority of Lighter utility/cargo/boat trailers as well as alot of vehicles and light trucks. I usual lean towards 95lb-ft on trailers.
Do you have to jack up your car to tighten lug nuts?
3 Answers. Nope, doing it with the wheels on the ground if fine, no need to lift the weight of the wheels. It’s easier that way because the wheels can’t turn while you are torquing the lugs.
Should you use an impact wrench to tighten lug nuts?
With an impact gun, you aren’t applying any torque to the wheel, either. You are applying shock and inertia to the lug to get it to come off. Do not use the impact to tighten the lug nuts , though. It is very easy to over torque them.
Should you loosen lug nuts in a star pattern?
Tighten the lug nuts in a star pattern, not a circle pattern, so the wheel gets seated snugly . This assures the wheel isn’t askew, and doesn’t then pop into the proper place while you’re going down the road, loosening some of the bolts and causing wobbling or worse — like the nuts breaking and the wheel coming off.
Will a 1/4 inch impact driver remove lug nuts?
The short answer is yes , but it depends. You can remove lug nuts of your car using an impact driver provided the nuts are tightened at the right amount of torque (80 to 100lb-ft) and your impact driver’s output torque is higher than 100lb-ft.
