My new 2011 V6 Mustang has 18" wheels. I purchased new snow tires just last season for my old 2008 V6 Mustang which had 17" wheels. I would like to use my GoodYear Nordic Trac snows on 17" wheels on the 2011. Is that possible? If I buy 17" alloy wheels for the snows, will there be clearance issues on the 2011? I'm concerned about clearing the brake calipers.
