I checked out a bunch of others and could have saved a few hundred but had the money and decided to pull the trigger on these. I went with 225/40/18 up front and the 255/35/18 in back. Looks sweet!
I gotta say, the ride is MUCH improved. This is a DD that will never get tracked, just driven with spirit once in a while. You guys were right, that harsh RFT feel was not necessary, and I'm already glad I went this route.
Question I have is what's the best air pressure? I am running 38 front and 40 rear right now. I think the tire place had 34 up front and 36 in back when I got it back. Any advice?

I just keep with the recommended BMW pressures - 36 front, 39 rear, but check your door jam/manual to see if that's what was recommended on your year. Gill @ Tire Rack I believe said you should still run the same recommended pressures in the PSS as the runflats. So, I'd start there, and then adjust if you want.
