new tires. I decided to go with 225/40 and 255/35. And I am glad I did. On the freeway sweepers ~90+ mph, the car felt more planted. It reminded me of my Cayman S and its 235/40 and 265/40/18's. BMW should have made these tires standard. I had to pay ~$1000 more. The tires are definitely worth changing. The run flats totally suck. Moreover, I only buy Michelin, Pirelli, or Continental tires for the street. I don't track.
