You say that but I have yet to snap a stud and really only do it when in a pinch (normally if I change a tire//wheel I have the proper tools).

I don't recall saying anything about breaking studs. I only said it puts side loads on it. The next step would be snapping or cross threading though. Just do it right and none of that would be a concern. Some people just love to justify an incorrect procedure.

I think there is also a certain number of rotations the lug nut needs to make for it to be considered safe.

I believe I also mentioned I do it with proper tools normally but I appreciate your concern (TBH I haven't had to change a wheel without a torque wrench in about 10 years so it isn't a real concern of mine).


Also, justification does not imply that I disagree with your method or that I think mine is correct. a justification is what it is, which is my rationalisation as to why I did it that way. Yes your technique is the correct one but some people may or may not have injuries physical ailments that prevent them from generating the leverage required to properly tighten the nut (aka my back and knees are fucked and depending on the day I may not be able to generate the force needed without suffering from back pain for the next few days or my knees letting go and winding up face first in a fender).


That being said in an ideal situation you are indeed correct

I love talking with sensible/intelligent individuals. I second every single point you just made.

I like to argue but I can also see reason
I'm part troll part sensible reasonable person. Makes for entertaining conversations at times. As long as the person I'm having a discussion with is basing their arguments on facts I love arguments/discussions. My problem resides when people start using emotions, trivial shit and circumstantial evidence that I have issues. (In other words, I enjoyed our exchange)


Seriously though the faceplants are no fun... ask me how I know

Well, now lupindub, I reckon you didn't do it right the first time ...... or ..... you had the studs oiled up ........

In those cases, I would suggest the "humfrz method".

Put key in ignition, drive up to a shop, have them switch/rotate/whatever the wheels, have a cup of coffee, read car mag, pay them, drive home, take a nap .....

Tire shops have the worst coffee though.

+1 that's why I said in a pinch I'll always have a torque wrench to change wheels unless I get a flat tire in the middle of bumfuck nowhere and that's where my incorrect method can come in handy (as in stuck somewhere with no cell reception to call said shop or towing company).


anyways I'll take that situation anyday over my engine blowing up in -40 weather and me having to wait 3hrs for a towing and nearly getting frostbite on my toes.

I'm going to have to disagree with you there, TCoat. In fact, I think over-tightening of lugs is a big problem these days. On the FR-S/BRZ/GT86 Enthusiasts Facebook group (which is comprised mostly of morons) people are routinely snapping their lugs. The proper torque is less than 90 ft-lb, which is definitely less than "jumping on the wrench" as some people here have suggested.

In fact, if you're having to jump on the wrench to break your bolts loose, they were over-tightened to begin with. Everyone thinks these studs are weak, but I'm pretty sure people just are over-torquing everything.

I knew I wasn't the only one who remembered those ads!

Also, seriously, with the overtorquing thing. I've always put on and off wheels with an impact gun. Never broken a stud. Even rusty-ass 20 year old studs. Are people cross threading and side-loading and trying to crank them in with the wheel halfway off or what? WTF?

On that note, side loading. I can snap a stud clean off with a breaker bar. But not by turning it correctly. Set the thing parallel to the stud, or even 45~60 degrees off with the lug nut crossed up and not tight against the wheel, and push. SNAP. They aren't designed to take bending forces. Shear and tension. Not bending.

Buy an impact gun. There are many great uses for one. Torque the f*ck out of them.

I will rephrase. I would tighten them as much as I could by using my arms and then give another tug with my arms. I am not Hercules so doubt I ever once over torqued a lug nut.
Also a good number of those broken lugs will have nothing to do with torque and much more to do with side loading the lug. Pretty hard to maintain even loading when you are jumping on one side of a lug wrench.


EDIT: LOL What Spart just said^^^^^

I suppose we will have to agree to disagree on the use of an impact gun to tighten lugs. That's all well and good until you have a flat on the side of the road, and don't have your impact gun, and suddenly you can't get the lugs off by hand. I've helped several people remove lugs that were clearly put on by a tire shop with an impact gun and in some cases we actually DID have to resort to the "find a 300 lb guy and ask him to jump on the wrench" method.

This frustrates the hell out of me because the whole goddamned point to having a spare tire is to be able to change it yourself in an emergency. The whole concept of a spare tire goes out the window if someone has to call AAA because some idiot torqued their lugs to 5 million lb-ft.
