Everything is a trade off, and to that end the 245/265 combo is the best trade-off for most, which is why BMW spec'd them.

This is a good discussion. Why does the M3 and M4 have 255/275's installed as standard. Do you think the cars weight is a factor? My guess was that BMW did not want the M2 to out perform the M3 or M4.
I switched to a 255/275 set up on my 17M2 using PS4's and felt like the car handled better not to mention the tires filled the arches better. I have PSS installed on my 21M2C and and plan to switch to PS4 at the first opportunity. I felt more confident on the larger tires.
