I think it is all in the tires, since they are a much wider tire on the front compared to a normal 70 or 75 series tire on most cars. I suspect my new tires will eventually do the same thing down the road. The F1 AS did take of the problem for now.

One thing to condsider for the guys that do front end work - I am curious if more positive caster would help the car to stay straighter? Caster does not wear tires uneven, but more positive caster can wear out steering parts faster.
