Over-torqued lug nuts are a pet peeve of mine...

And yes, I've snapped multiple studs over the last couple years getting them off. It's a combination of the initial over-torqueing, then me applying heavy off-angle pressure with the tire iron (me standing and jumping on it to break them free). Hopefully now that I've got an impact wrench, the off-angle pressure isn't a thing anymore.

Heh! That's how I've broken a ton of studs too. Standing on the Toyota lug wrench, and bouncing, to break the lug nuts loose.

Now, I watch, and make certain the tire guy ONLY torques the lug nuts to the FSM spec. WITH a torque wrench. Most of the guys are pretty understanding, although a few have looked somewhat annoyed that a non-tire guy is telling them how to do their job. Too bad, though. I'm paying them, they can do it right. The way *I* say to do it.

My regular mechanic does it that way, cause they know, after taking vehicles to them for a while now, that if I have to, I'll stand over their shoulder to make sure they do it right.

Have fun, all!

I've actually seen tire guys shear off a lug nut using an impact wrench, so it's not just because of off-angle pressure. I guess mechanics don't want to be bothered to check torque specifications for every bolt. It's too time consuming.

My mechanic is great. No complaints about him. But the people working at the the tire shop are NOT mechanics…and it shows.
