Bontrager H2s. Would like Continental Sport Contacts for better grip on pavement. H2s I notice some rear wheel slip, and after only 300 miles the rear tire is noticably more worn than the front.

Had some sort of Cheng Shins on another bike, which were outstandingly amazing for a cheap tire. Two years with no flats and only had to put air once after the bike had sat all winter and the grip was really very good.
