[AT] Lug Nuts

[jtchall at nc.rr.com]

Got a 66 Mustang I bought in 87. Its got some really weird chrome rims--they 
have slots instead of holes to fit different bolt circles. They use a 
shouldered lug nut. You have to slowly tighten them up or you will cause the 
shoulder to pinch. When I got the car we had to use a 3/4" air wrench to get 
some of the lug nuts off.

Every tire tech I've ever watched just runs the bolt/nuts up with no regard 
to what should be happening. I always run them up slow, sometime by hand. 
Then I set my torque wrench about 15 lbs lower than what is called for. Once 
I torque them at that setting I adjust for the final torque. I will confess 
I only torque aluminum rims. Everything else I tighten by hand, unless we 
are talking tractor tires, then I'll use the air wrench. Even then I 
progressively tighten them. Might be a little overkill, but it works for me.

Something else I have noticed:  tire shops are generally careful with torque 
on lug nuts on cars.   I can usually get them loose with no trouble.  But if 
they get their hands on your trailer/tractor or whatever they whip out the 
impact wrench and just wail on them.  Not sure why they aren't as careful.

You may have been the victim of a tire technician with more impact wrench 
than brains.   (-;
