Dunlop recommends 28/36psi front and rear for the Mission on the AT. But I am not sure whether it would have made any difference.They were set to 36/41 actually for the ride, double checked when I got home and pressure somehow managed to maintain itself perfectly.
Glad that you got down without a heatstroke issue. We were at a rally over the July 23/24 weekend and there were a couple of incidences of heat stroke. Nothing to mess around with.
