Hi, I just got a 2012 WRX and am looking at winter tires (I will be getting 16x6.5 steelies). I looked at many threads but non tailored specifically to those sizes. I've seen some people run 205/60 for winter tires and some 215/55. Is there any huge difference in performance? The 205/60's are about 75 dollars cheaper than the 215/55 setup. Any insight would be appreciated!
