So My Mother has an 06 328Xi coupe with the 18 inch wheel option. The car has performance ties on it and they just dont cut it in the winter for my mother, i have a set of my M68's form ym E46 with snow tires mounted on them, the offset will look wierd but i am confident they will work, my concern is the tire pressure monitor. Will it give me a problem or will it jsut show that there is an error?
