I likely will be trading in my 2013 WRX for a 2014 STi. Last winter I had a dedicated set of snow tires: General Altimax Arctic 215/55 R16 on black steel wheels. I chose that combination based off recommendations on this forum. However, being that the bolt pattern on the STi is different than the WRX, I will need to mount the tires on a new set of wheels to use them on the STi. I was either considering doing this (assuming there would be no issue with this combo on a STi?) or selling the combo to my friend or someone else with a WRX and buying a new set of wheels/snow tires. I've read Nokian Hakkapeliitta R's are pretty cream of the crop when it comes to snow tires, however, they are fairly expensive the larger the wheel diameter. Would you aim to stay around the same dimensions of 215/55 on a 16 inch wheel for the Hakka's as one did for the Altimax Arctic's or would you err towards a larger diameter wheel as a base closer to the OEM 18 inch wheels that come on the STi?
My best guess is that when I do ultimately trade in for the STi, I will likely have to already have the set of wheels for the winter season ready to go right on. Therefore, I'm trying to figure out what route I'll have to go as early as I can. Thanks ahead of time for any and all feedback!
