Anybody recall what the recomended torque for the lug nuts on our cars are?
hmmmm, if I recall correctly, for most aluminum wheels is about 110-115 ft lbs, or somewhere in that neighborhood
100 ft-lbs

it has nothing to do with the lug nuts, the torque for the j-bodies (and 98% of GM cars) is 100 ft-lbs.
make sure your lug nuts and studs, if not original from gm, are rated for 100 ft-lbs. some lug nuts will have it stamped on them, i have seen these on some fords.
there is a reason behind the torque being 100 ft-lbs that has more to do with just having your wheels fall off. buy yourself a torque wrench aswell if you do any work yourself, it is a must have.
ps- the torque for our wheel nuts should be in the back of your owners manual, mine is atleast.
Injection is nice but id rather be BLOWN!

I've been told plenty of times that you should tighten tuner lugs to 90 ft-lbs instead of 100.
You're right in that 100 ft-lbs is the proper torque for stock lug nuts.
weasel, the tuner lugs may not be able to handle the recomended 100ft-lbs.
i remember doing some wheels on a mid to late 90's f150 heavy duty. the recomeneded torque for f150's is 100 or 120, cant remember now... but the f150 heavy duty calls for 140 because it is built off of the f250 platform. difference is 6 lugs insead of 5 lugs on the regular f150 aswell.
so what happend was the torque we had set on the wrench was 140, but the nuts were only rated for 100ft-lbs. we shreaded the hell out of a few of them before we realized.
now the tuner nuts seem to be designed more for hondas (80ft-lbs) and volks (81-89 ft-lbs), not our slightly larger j-bodies.
now with a 10ft-lbs difference in the torque, i doubt they are going to fall off. i would torque them at 100 if the nuts are rated 100 or higher, if not , as high as they will go.
like i said, before get your own torque wrench, then you can check them every week or 2 and make sure they arent loosening. you dont want a rim to fly off and be left sitting on your brakes...

I've never had mine loosen. And yes... you should definitely be using a proper torque wrench to put them on.
Yup Yup 100ft lbs. says so right in my GM service computer.

what happens if they are too tight
Too tight can warp your rotor or damage your wheels.

consequences of lug nuts being too tight...:
- warp rotors
- damage wheels
- damage/ strip studs
- leave you stuck on the side of the road trying to put your spare on because you cant get the nuts off
im sure there is more, but does it really matter? i think the above would suffice.
also, when torquing wheels, make sure there is no anti seaze or grease on lug nuts or studs. studs must be as clean as possible or torque may not be to spec.

Oh just remembered busted nose from trying to over tighten them and the stud snaps and you fall flat on your face.

I think that the biggest problem to be concerned with is damaging the lugs or nuts. When damaged, they can break. Breaking them can obviously cause some pretty serious mayhem.
this GM tech that is writing this says 100ft-lbs......
