Fits fine on OEM wheels. No spacers. No rubbing.

These were my favorite track tires on my GT-R before I traded it in on this M5. Strangely enough, the rear tire is also the EXACT same size as the rear tire on the GT-R, 2009-present.

The GT-R world has a LOT of experience matching the front and rear tires. The GT-R's transfer case will basically self destruct at high power of the front/rear outer diameter is a bad match. But sizes are basically unreliable. Either square or a rollout is required to be absolutely certain.

Even though the outer diameter is SLIGHTLY different on square tires on different width rims (OEM's are different in this M5), it was not different enough on the GT-R to blow the transfer case and the front rim and rear rim were a full inch different. So this should be fine. My testing so far is perfect. But I take it to track next week. Here ya go...
