Question What's the best tire pressure?

I'm getting a Gary Fisher HOO KOO E KOO with Panaracer DH Pro tires and Maxxis DH Tubes. I'd like to know what tire pressure would be the best for the kind of riding I'm doing. Unmaintained gravel roads, atv trails, mountains, rocks, tundra, mud, soft sand etc. The longest I have done so far is 2 hrs and that will increase by a lot.
I weight 185lbs and 5' 9.5", age 53 and I am not going to do any jumping.

I've got DH tires on my Giant, and they say no more than 60 psi, and I've done fine with 60 psi on tours of Michigan, and that included all sorts of terrain. Your tires may or may not be 60 psi max like mine, they may be 65, but in any case, I would reccomend that whatever the max is, keep it there. To little pressure can cause pinch flats and rim damage, and to much pressure can and will blow out tubes.

I only run my tires at the rated max pressure (60psi) if I'm riding on paved roads. If I'm on technical singletrack with obstacles such as roots, rocks, steep climbs, etc., I usually run 30psi.

It mainly depends on the terrain. The more traction you need, the lower the pressure. Much also depends on your weight. To prevent pinch flats, heavier riders require more tire pressure than ligher riders.

There is not a single "best tire pressure" for the varied places you have listed.

I forgot to mention the tire/tube sizes:
Tires Panaracer DH Pro 2.3" wide and the Maxxis DH tubes match and at a 430gr.

Have to agree 100% - I love to run single track at 35 psi. Amazing what one can climb and negotiate with squishy rubber grabbing the trail. On the pavement, I feel bogged down, so I'll up the psi to 45 or more. At that pressure, I literally get kicked and bounced on the trail.

I'm 5-7, 135 lbs. Not sure this applies to much bigger riders.

Well I just tried it at 30 lbs and my boy at 20 lbs off-road and much better. Now I'm going to try mine at 50 lbs and his at 40 lbs on asphalt. I have been pushing myself lately with no time off and now my muscles are intoxicated, plus have been running to soft on the hard surfaces. Anxious to see how it will go with the new method.
Man learning is so much fun.

But am on edge, cause I can't wait to get my new bike.

Pressure depends on bodyweight, type of trail, type of bike. I ride hardtail on fairly rocky trails and am pretty light at just over 11stone. I ride 45 front and rear. Might take the front down to 40 to soften it up a bit.
