I just purchased a 2015 200s in October I love this car well anyway my car came with 18in all black factory rims tire size 235 45 zr18. I live in Rochester NY the winter here sucks a long with the salt they use here I was thinking of purchasing some 17in rims off a different model 200 or 200c of the same year for the winters. My question would be would the 17in fit on the 200s and if so what size tire should I get. Thx
