What are the torque specs for the wheelnuts?

90ft/lbs would be fine

IIRC, the manual says 80.

Dosent it depend on the type of wheel? Stock vs Aftermarket and the type of alloy. Steel vs Alumnium

OK, stock aluminum's, 16 inch.

80.

For my 90 Camaro, it's 110 Nm (81 lbft) regardless of wheel type. This is for an M12x1.5 nut.

hmmm... I'm torqueing mine to 94, just like I did my crown vic with 16" alum. wheels. No issues yet.

Perhaps I should back 'em off?

Torque spec doesn't care if it's steel or aluminum. Torque spec is based on stud diameter. The 12mm stud is similar to the old 7/16" studs. 80-90 foot pounds is fine. Never use an impact. You can overtighten and stretch the studs plus you'll curse and swear when you need to fix a flat with a tire wrench on the side of the road.

I use my impact all the time... Works fine for me. You just gotta know how to do it, I used to change tires all day long for a job, so I used the impact alot. Untill the changed the rules and made us use a torque wrench!

If I dont feel like charging up the compressor, I will just use the 4-way. I put them on as tight as I can. Always easier to take them off.

A 4-way as tight as you can get it???? I'm a 170lb weakling, but I think I could break a stud off with my 4-way pretty easily.

I'm a kinda big fella and I can over tq wheels with a quarter drive ratchet. no joke.

ALWAYS use a TQ wrench.

My `88 factory manual says 80 ft. lbs. for all wheels

I agree, i use my 1000 ft pnd impact gun every day and have never ever had a problem and i dont even thread them on i just zap them on with the gun.

u just cant sit there and let it keep hammering lol or the stud is gone.

( saying this to not discourage the use of an a impact) Torque sticks are actually good 2

I do use a impact to run lug nuts down everyday to.
Im just saying you need to check them with a TQ wrench..

Personally i don't to my own car, but i can understand why someone would

you dont need to torque them, the impact is overkill its fine to use the impact to spin the nuts on all the way if its allready out but barring use of a torque stick i wouldnt recomend hammering it on trying to tighten them with it (not because you cant because it can be a real bitch to extract a broken stud) that said i allmost allways use either a 4 way or 2 foot breaker bar as tight as i can without jumping on it or anything thats about 80-95 ftlbs wich is fine for pretty much any car unlike say...heads lug nuts arent really an exact science

I use a 100ft/lb torque stick and forget about it. That'll put it between 90-100 ft/lbs, never had a problem. Anywhere between 80-100 ft/lbs is fine.

At Discount tire, we torque all camaro/firebirds at 100 ft/lbs according to a certified chart thats updated each year. Im sure 80 would be fine though. The wheels shouldnt fall off or anything.

I put them on at 75ft.lb because that is as high as my torque wrench goes. That is not tight enough, I know. I have to retorque them a second time a few days later (the nuts all ways turns a little bit) and doing that has been good for as long as I have owned my Torque wrench, since 2002 or 2003.
If your only going to do it "One time" yea you would want to do it to 100ft.lb.
I don't want to break a stud or sink the nut through the wheel.
When I was in japan there was a rash of wheels falling off cars and trucks due to a faulty impact wrench at the hobby shop on base. It went on for about a year untill they figured it out.
