Torque specs for lug nuts?

[SMEGMA STENCH]

Yeah I could have googled this but I'm too fucking lazy. Often I have wondered what the typical torque specifications are for just your average half ton truck. Or perhaps your average 4 door family sedan. Does anyone even care? Or do you just tighten them down till they feel snug? Or, do you just know that 150 PSI of air pressure must be enough... right?

It's more determined by the size of the stud than the size of the car. Typical 1\2 ton chevy 1988 and newer 120 ft lb's, most midsized cars 80-100 ft lb's, 3/4 ton and up anywhere from 120-175 ft lb's. A lot of euro cars with lug bolts instead of typical stud and nut are 65 ft lb's. I use torq sticks and or torque wrench on all my customers cars. I've had to take many lug nuts off with the 3\4" impact after someone hand tightened or just used an impact.

Hmm, this raises a new question for me. How can you be sure that you're impact is going to torque them to spec? A certain air pressure coming through the wrench = a certain torque setting perhaps?

If you have the proper torque extensions, which most will not. Otherwise, you need to use a torque wrench. Check each by hand. If you deem it necessary.

Tight till it breaks, back it off a 1/2 turn. ;-)
I've heard 90ftlbs, but I go by feel.
