    Too many variables to give you a direct answer.....Depends on your weight, riding style, terrain, tire/ tube setup, etc.........

    True about the variables when setting up tire pressure. Trail conditions dictate my tire pressure changes. I run mine low. 17-22 lbs on my Kenda Nevegal stick e's. I weigh about 165 lbs and have never flatted a DH tire LOL. Smoothness is the key. Now, the XC/trail bike is a different story but I do things with that bike I shouldn't haha. Tire pressure on that bike is usually 22lbs give or take a pound or so. I run tubes with all my rides.
    I'm thinking about shreddin' it up right now!

    I seem to pinchflat doing DH if I run much less than ~30psi. I run minion DHF/DHR 2.5s w/ tubes. I'm not even that friggin heavy (~160-170lbs)

    I run 20lbs up front with nevagal 2.7 and run 25lbs out back with minion dhf 2.7 of course this is on wide DH rims. The more narrow the rims the more chance of pinch flat, so you'll have to up the psi...ralph
    i need to ride more. building jumps takes to much time...my other hobby is kicking the crap outta my home built mook jong.

    Heavy tubes with PSI between 22-27. Higher PSI if its drier, less its wet.

    28 psi, or lower it until you start pinch flatting, then go up 2 psi.

    What width do you consider wide? I'm running dt 6.1d in the rear (32mm outer width) and can't seem to find much wider rims (not built wheels) that are meant for DH/FR.

    Tire pressure for DH

    If I run anything lower than 30psi my tires roll in corners, bad.
    30f/35r, 99% of the time.
    I'd rather have a bottle in front of me than a frontal lobotomy.

    nope.
    inflate to about 40 lbs - this seats the bead.
    Drop pressure to what is required by your riding.
    You can drop the pressure until you start to feel roll the tire over, or pinch - at this point add 2 lbs and try again.

    Every tire has a sweetspot as far as a balance of grip and pedalability. With a bit of experimentation, you will be able to find this spot.
    ..and unless you are a clyde or a pro, most of us end up running the pressures below what is stated on the sidewall.

    ...I build my own wheels and the reason being is a long time ago I stopped trusting shops to build my wheels, they would never hold up. as for the rims I have their atomlab DH rims and I'm pretty sure you can get rims wider than 32 mm but i've been outta the loop for a few years...ralph
