My tires are bald on the outer 3 inches. I am concerned that my alignment is toed out. I have had several comments from people and mechanics that it is not right for them to be so worn. I am at 4500 miles, but the back tires are fine, and the inside of the front tires look fine. but the edge is slick with no lines of tread left. I am not that aggressive! Why didn't Fisker put run flats on this car? Has anyone tried a different tire?
