In Jan, I got an alignment through Firestone. It's in factory specs, but all four tires the inner walls are fading at a rapid rate. My tires were 6's and 7's tread wear so pretty damn new. Stock suspension at 94k miles on it and all I have is strut towers front and rear. Does this mean my struts are bad or bushings ? Not sure but I have to do something fast before I throw away hundreds of dollars again.
