I just purchased 225/50ZR16 Goodyear F1 GS-D3's and they are excellent. I only have about 100 miles on them so my comments are initial. I will autocross them this weekend and I will fill you in. I bought them because of the reviews on tire rack from bimmer owners, and they had a $60 rebate.
My initial impression is that they grip insanely well on dry pavement, and they work well under repeated hard stops and hard cornering. They are exceptionally quiet, far quieter than my Dunlop SP 7000's that I had on my Acura Legend, which were 205/55R15's if I remember correctly. The tread compound is different than what I am used to, it feels strange to the touch. I haven't tried them in rain yet. I also like the fact that mine are made in Germany to go along with my car
I don't know if all of that model are made there or not, it might be random.
The road feel is different, the car feels lighter on its feet, and has more body roll. I am assuming that the added body roll is coming from the added tire grip. The tires have excellent feel; it is easy to tell when they are about to give, but I don't have much to compare it to. The handling limit is very high with these tires, I take a corner at 10 mph faster than I did in my Prelude with good tires on it, with a lot more confidence. My old 318ti tires were 3 different brands, and all worn past the indicators. The would squeal when I wasn't doing much of anything and the ABS locked up a few times with them. It is nice to be rid of those old worn out things.
I have used General XP 2000 VR4's in this size before, and they sucked for high performance, but were excellent year round including the snow. These goodyears will be worthless in the snow.
