"Tom Forhan" <TFORHAN@HR.HOUSE.GOV> said: 1991 200 Quattro Wagon FS . . . . Tires are Goodyear Aquatred in front, TA's in rear. Tread OK. -- My quattro owner's manual says you must use identical tires (same manufacturer & tread pattern) at all four positions otherwise it could ruin the torsen differential!
