I just picked up my M340i RWD and have it outfitted with the 19" rim and Pirelli P-Zero performance run-flat.

I have only done a few foot stomps (freeway metering light onramps) to get familiar with the driving dynamics but I instantly thought to myself the 255 rear tire was barely keeping its composure with all the available torque.

I'm wondering if other M340i drivers are feeling like a slightly wider tire might do better, and if so, what are you looking for?

My old 2011 Lexus IS-F has a 255 rear tire and the OEM rim could fit a 275 wide tire... the wider tire had a huge benefit off the line and in the corners. So I'm looking to try the same thing. Thoughts and opinions?
