Tires wearing on outside

[theastronaut]

Toe out wears the inside of the tires, toe in wears the outside.

Negative camber doesn't wear tires unless it's extreme, I run -4 front and -3.5 rear on my autocross/daily and tires last 20k+ miles driving it aggresively.

My other car has slight positive camber and will wear the outside edge a little faster than the rest of the tire, but it doesn't have any camber gain geometry built in, low caster, and has very soft suspension that allows a lot of body roll so the outside of the tire really tips over in corners.
