You absolutly can warp things. As you said, if you don't get them evenly torqued. And using an airwrench does two things, uncertain torque and usually massively overtorqued.
But, even more important, if your wife, son or daughter, is driving the car and can't change the tire with the normal gear in the car that's just wrong. I don't want anyone in my family stuck because a tirechanger didn't follow spec, on *anything*.
I watched a guy use his airwrench while rotating my tires (won't reveal the chain...) and before the car hit the ground got the manager and reminded him that one of their points is "we use a torque wrench to mount tires" and had him use a torque wrench to try and remove a wheel. Most 1/2 inch torque wrenches are longer than the kit in the car and therefore have a mechanical advantage. Plus this is a guy that helps out in a pinch. And, it was still in the air and he used his body weight too. He could not ** Budge ** any of the nuts. He had the installer airwrench them off, and redo the job properly.
THAT'S JUST WRONG.
I've harvested Super Aero rims at the junkyard and had to use a 2 foot long 1/2 drive breaker bar WITH the handle from a floor jack and my entire 245lb body weight to break the damn things loose. This is the same setup I use to put the 240 lb/ft on the wheel nuts on my 900's, and even then it's not that hard!
Too much torque is two pieces...
