Here's an anomaly for you all:
The right front tire (less than 10,000 miles) on my truck shows serious signs of being towed out, but the caster, camber, and tow as measured on two completely different systems show it to be close to the center of specs.
The only issue I've had was with a warped rotor. That, however, would have caused wear on only a portion of the tire, and in any regard, I replaced the rotors several months ago, and she's glided to a stop like a baby ever since.
Addendum: I put the studded tires on at the same time I replaced the warped rotor. The studs show no sign of abnormal wear. Only the summer tires show that. They're kept on different wheels, but the wheels measure true (round), so I'm at a loss as to what might be causing this. No abnormal wear on the studded tires.
