I'm looking to pick up a set of used wheels to mount snow/winter tires for my CMax. Is there anything special or unusual with offset or other specification that would limit what would fit on a CMax? Lots of used Volvo, Focus, Escape used wheels on Craigslist in 16 or 17" with 5x108 lug pattern but virtually nothing specifically from used CMax. I was planning to get wheels and then appropriate size Blizzak or Michelin IceX tires to fit. Any pitfalls????
