Well, I am about to order new tires. I'm looking at either a 2.35 High Roller or 2.5 Minion for the rear, but I dont know if it will fit. I measured my frame, but I'm still unconvinced. Has anyone ridden/seen someone running a 2.5 on a P.2. I think I've seen one with hookworms, but can't dig up the picture. Any help would be much appreciated. If worse comes to worse, I'll just order the 2.5 and hope for the best.
