Tire pressure depends on many factors, but what I generally do is inflate front and rear to 35 psi, then bleed some air out of each tire during the ride until things feel right to me on that day and that trail. I don't bother measuring the 'end of ride' pressure because every ride and trail is just a little different. Beware if you bleed out too much air you'll risk pinch flatting. Also, with front suspension, you can usually get away with slightly less pressure in the front tire. Maybe 3-5 psi.
