Setting up for fire roads and moderate sand/mud tracks, no jumps unless I screw up and go off a cliff then it doesn't matter. Front tire Wierwolf 2.5 and rear Nikon NBC 2.1 on a Specialized Endure. I'm 6' and weigh 200#, bike weighs 33#. Looking for recommended air pressure guidelines and suggest what I should initially set up with. Tanks.
