The Pirelli's are readily available from any of the big online supply outlets. They are a big improvement over the Metzler's. They have been the OEM tire for several years now. Michelin's are good too, I got good mileage with them, maybe a little less sticky than the Demon's. Just put on a new set of Pirelli's, but thinking about trying Avon's next time. Hard to go wrong with any of the European brands.
