Interesting coincidence. Just yesterday I went to the Tirerack website and saw that their recommended snow tire size for the 2008 smart car was the 175 for BOTH front and back. I immediately called their Technical Support people and told them to research that recommendation since I thought they would be open to some liability. (If that combination would work, why in Heaven's name would smart go through the trouble of putting two different size tires on their stock vehicles, I explained). Further confusing the issue was Tire America's recommendation for the two DIFFERENT size tires on our 2004/2005/2006 European converted smart cars in the US, just like the stock vehicles. Not sure, but I imagine Tirerack's recommendations should change on the 2008's sometime later this week... but maybe not, based upon the other feedback in this forum...
