If 1/2" I will guess 75ft# Looking it up from the manufacturer is gold. Jim

If the lug bolts are one-half inch fine thread the torque should be 100 foot pounds.

That's for a regular half inch nut, not a conical lug but which has more friction

Whatever feels good to you with a 4-way lug wrench should be good. I'm 70 years old and I've not lost one yet.

Over-tightening is just as bad as under, and at $20 for a cheap torque wrench, I'll do it my way thank you.

I'm sure I'm not doing it right according to others. I put everything at 90 pounds motorcycle wheels car truck trailer tractor farm equipment whatever haven't lost a tire yet or come close to doing so.

Just to clear up torque values here is a chart. However I am over 80 and never used a torque wrench when tightening wheel nuts or studs and never lost a wheel.

I worked at Demco Manufacturing back in the day-- they built trailers for the rental people -- We set the lug nuts to 120 ft. lb;s -- Roy

That's for regular bolts, the increased friction of a tapered lug nut makes a big difference

A cone lug nut on a 1/2" stud has a torque range of 90-120 lb/ft, 9/16" is 120-140 lb/ft. Being at an exact number is not as important as being in the range.

i don't know what they should be torqued at, but what ever the tire shops tighten to is way over done. try to change one with the tools your vehicle comes with out on the road and you'll have a whole new look on it.

Just to play devils advocate, This is all for Nuts and studs. What about Cap screws instead of studs?
I just used what seemed right and not lost any wheels or twisted them off.
