I think I am getting a 2006 Honda Civic Si and I am going to get rid of the Michelin Pilot HX MXM4 tires and put on avon tech m550's. What should I do with the MXM4s? They will be like brand new. Should I sell them on ebay/craigslist or will used tire places give me a deal?? I am only really looking for a direct swap, the avons are $100 each on tire rack while the MXM4s are $185.
