I decided to replace my 255/40/19 year old Michelin pss with 245/35 because it been rubbing all the time i go on dips and bumps it drives me crazy to explain people what happening. only thing is to get M5 fenders to eliminate rubbing that i really do not want do. i have new M5 oem 166s and need a reputable tire shop in LONG ISLAND NY BY JFK area with road force balance. i have few but still can not trust them as had bad experience with them and allways was wandering if if they really do road force or not. help.
