they have just those tire...Kenda Happy Mediums, 32c versions are Tubeless and can be had for $35ish bucks each. Much cheaper then the spesh tubless 23/25 tires. I have a set of those as well for the road bike wheels. I ran the Schwalbe Sammy slick version 34c tires for about 500 miles before getting a set of the 32c Happys so I can run them tubeless. They roll well at 20mph, cuz the knobby sides, I don't recommend leaning them too far over on pavement like you would real slicks.
