I throw my tires on with an electric torque wrench at home, take a short drive, then finish off the bolts with my spare tire wrench. All by hand, no torque wrench.
How many people here do that is a good question because for being this anal about wheel torque, a lot of the time it doesn't even stay right after the first bit of driving around.
Reality is if its so tight King Kong can't get it off yeah; thats pretty ignorant, because I've tried to change flat tires on cars before where you have to stand on the tire wrench to crack the bolt free, and thats absolutely overkill and making it impossible to change a flat, but I think complaining about it not being down to specific foot-pounds within %5 of what the specifications are...you're worrying way too much.
Unless you got aluminum mag wheels or something because overtightening on that I've heard can be a nightmare on your rims. Steel rims? Pretty much as hard as you can pull with one arm, for me at least, is about a hundred foot pounds. Never once had an issue.
If you wanna call me an idiot for it feel free. I will agree though that most tire shops are run by monkeys and I completely loathe the impact-everything-to-200-foot-pounds mentality.
