The Dunlops do not like freezing temps they can crack if smacked around. They were down on ft tire stock as well big shipment was missing ft.'s. Been testing the alpha's on 2 ktm390's and ran them at Jennings in endurance races and this past weekend on the ex250r they work good. psi is what works for different riders. I look at psi rise off track and core temp. we run 31 rear 29 ft for the most part hot off warmer.
