What are the factory wheel and tire sizes for the E36/8 M coupe?
All M coupes use the same size tires (225/45ZR17 in the front and 245/40ZR17 in the rear) mounted on one of two versions of the five-spoke “M RoadStar” alloy wheel. Both are sized 7.5×17-inch (front) and 9×17-inch (rear), but there are two distinct finishes: Early M coupes (S50 and S52 engines) feature a Chromeline finish, while the later models (S54 engine) utilize a darker Chrome Shadow finish.
