I cant find the answer(s) to this question I asked some time ago.......I have a 2011 M2 with 15 inch wheels. What size tires will fit with no issues...I would like first hand experience only....Thank you...Mark
If you are using stock wheels pretty much any tire you can find to fit on the wheels, with roughly the right outside diameter, will fit on the car. For a while I was running the stock wheels with 195/s and 1" wheel spacers and it fit no problem. They looked great which is why I did it.
I've got the 205/50-15's, too. My wheels are 7.5 wide, so I thought I'd go just a tad bigger on the tire width, too. If my wheels were 7 or 6.5 wide, then I probably would have gone with 195's.
