Difficult for me to say, as I have never tested Sottozero RFT. But there are generally huge differences in performance between different types of winter tires. As I mentioned earlier, I drove an M Coupe (321 hp) with winter tires on a cold and rainy day. It was not possible to break traction in first gear in straight line without dumping the clutch. The car did not have traction control. The F20/21 has a longer wheelbase, and thus less weight transfer to the rear tires, but it should still be possible to get a lot of power down.

Maybe the M135i needs a limited slip differential after all?
