I'm new to the board and a new bmw owner. i upgraded the wheels to 225 40 18. the previous owner had them on a 1998 328i. well after getting the car on the road with them on there is alot of noise coming from the rear end. Sound like a rub because there is alot of noise that gets louder as I go faster. I ran my hand all the artound the wheel and couldn't find any rub spots. Does anyone have any ideas what the heck that noise is..
