Well, just 4 of them and the closer to Missoula, MT the better. I bought an '08 scion xD and the previous owner put 17" rims on it and now I have a pair of 17" snow tires with no rims (don't want to remount every winter/summer). It looks like the tC came with 17" with a 5-100 bolt pattern for the most part so how about cashing out your old rims to help pay for those sweet new rims you put on your car? Anyone know if the TPMS from a tC will work on an xD? that would be sweet!
