I put on a set of stock sized Shinko Tourmaster tires on mine, and I'm impressed with them. They were a little slippery at first, and after 20 or so miles they seemed to be fine. I can lay mine over and drag the pegs, and it feels safe and stable. It handles really good for mid entry tires. I'm a big guy, 300 pounds, and I can throw it around with ease and not worry about it coming out from under me.
