On my 2004 Mazda 3 my rear tires a seem to be tilted ever so slightly in... / \ They wear on the inner edge of the tire not too bad but noticeable after 20k on the tires I drive to Atlanta every day 100 mi+...(highway) The outside edge looks new. I have had the tires rotated every 6000 mi and aligned every 10000 mi. So is there anything I can do about it, I would like to have my tires wear evenly. HELP(shocked)
