I'm surprised at how many tire installers will not inform customers about bent wheels and install new tires on them anyway. Also, it makes me cringe to think how many installers have so much faith in the torque of the air gun.. whenever I get new tires, either I jack the car up at home and carry just the wheels to the tire store in another car, or I tell the guy I'm going to put the wheels back on myself with my tire iron right there on the spot.
My cousin's F350 lost a wheel a couple weeks ago because the dip$hit tire installer didn't bother to put a breaker bar and a socket on the lugs after buzzing them on with the air wrench. My cousin said, "it's a really bad feeling when you see a 41 inch tire rolling past you at 60 mph"... i'll bet it is!
