ive got a 01 quattro and it has some sort of sport suspension on it cuz it sits waaaay lower than any other 01 a4 ive seen. anyway ive been running the 15" a6 wheel and am pretty ticked off because when i bought the car it had the 7-spoke 17" TT wheels on it. they werent on the car in the picture when i saw it-but when i got it, it had them. anyway the tires are 225/45-17 and ive already replaced the full set of tires 4x in 2 yrs. problem is the inner side walls are getting annhilated by something but when i feel behind the wheel and look under the car theres about a 1/2-3/4" gap between any suspension part. was also told that these tires are too wide for the car and are the reason my MPG's are literally ****. horribly bad. thinking about running a 205 or something but not to sure just yet, anyone know whats goin on here??
