I have the 4 plus.

255/40/19, that's the size I run. The V12s are available in that size but I think they are summer so your location will matter. My rims are 19x8 so I don't know if you will rub up front without some stretch or not.

I have that size Proxes on mine, they make a loud hum between 80-90 mph. I'm not that impressed with the wet performance either; my Falkens were better in the rain. My step brother got Falken Ziex and likes them pretty good. I've also heard good thinks about Hankook Ventus v12.
