I have a set of like-new wheels and tires from a 2012 Polaris 500 HO Limited Edition. They have approx 90 miles on them. They are on good shape. The tires are Kenda K590. Both wheels and tires are 12". I will be at Redbird all weekend, so let me know if you are interested and I can bring them with me. I'm asking $400 to start but am willing to deal.
I thought I would give an update as a reference for anyone else trying to sell something similar. Ended up selling these on Craigslist a couple weeks after I posted them for sale. The final selling price was $350. The buyer seemed to be very happy to have them at that price.
