Bringing the prepped 400 for the cooler mornings. The Q3+ rear got a huge slice in it and all of the air is permanently out...so I have a Pirelli diablo SuperCorsa 140/70-ZR17 mated on the rear to the Q3+ front. Does anyone know what PSI cold and hot this old tire should be set at? Best I could find so far is 23-26 cold, 25-28 after warmers but no great way to verify it. Anyone? Bueller? Stick? Mullet?
