IRC V33s (soft compound) on the rear with tubliss around 7 psi for this race. It holds up pretty good for a soft compound tire. Front is Dunlap Geomax AT81f. It was on the bike when I bought it. It has a little wear and it did not feel great in the slick stuff. It will be coming off soon. I've had good luck with the IRC ve35f on the front.
