I currently have my stock 225/50/17 potenza's up front and Blizzak 235/50/17 in the rear for winter. I'm either buying OEM 06 18's or something else aftermarket for this summer, but when winter comes again the front potenza's will need replaced. would it be a huge issue if I put my current blizzaks up front and bought brand new blizzaks for the rear for winter and just run 235/50/17's all the way around for the winter months?
