I dunno, from what I've heard, they don't wear out as fast as people say, as long as the toe is set correctly. Supposedly if you have normal toe, and even a lot of camber, the tires will wear close to normal. Obviously not exactly as long, but again, I'm not speaking from experience.
And tonight, I will try my hand at bending brake line!
Exactly. Hell, look at the back of my Bavaria. They all have excessive negative camber in the rear, just because of how the suspension is set up. It's common for old German cars to do that. The tires that are on the rear have been on the car for probably 25k or so. No abnormal wear anywhere. Toe is the devil. Camber... can hurt you in other ways, but tire wear doesn't really play a part.
