I'm new to this forum and have a few questions. I just found out my WRX is coming a month early!! I live in the Salt Lake City area and am wanting to sell my wheels and tires when the new car arrives at the end of this month (June 2013). First, what is a reasonable asking price, and second, has anyone traded them in with a local shop and then paid the difference for the new set up?? If so, how much is a reasonable trade in value?

Thanks
