2016 Grizzly stock tires

Just picked up my new Grizzly today! I had the dealer install new 27" ITP Mud-Lites before I took delivery, so I have a brand new set of the stock 26" Maxxis tires. The dealer said I could probably sell them on Craigslist for $350-400. I was hoping that some of you that have sold your stock tires could tell me how much they are actually worth.

Thanks,
Craig
