and when camber gets more serious (lowered), sometimes people dial the toe in a bit to compensate

 

Ok thanks!

 

From Tire Rack:
Additionally the vehicle's toe is one of the most critical alignment settings relative to tire wear. A toe setting that is just a little off its appropriate setting can make a huge difference in their wear. Consider that if the toe setting is just 1/16-inch off of its appropriate setting, each tire on that axle will scrub almost seven feet sideways every mile! Extend it out and you'll discover that rather than running parallel to each other, the front tires will scrub over 1/4-mile sideways during every 100 miles of driving! Incorrect toe will rob you of tire life.

 

I don't hit any potholes and have had 2 alignments done in the last 3.5 yrs, now with 28.5k miles.

First alignment was done within 1 yr of ownership as steering wheel was slightly off. Dealership did it under warranty. toe was off

2nd alignment was done a few months ago after I saw some slight cupping on the tires. $60 later at a rice shop, toe was corrected and tires now wear properly!
