    The less pressure you can run without continually pinging the rim from lack of air....
    but it depends mostly on conditions and the coarse.

    If it is a grippy coarse, more air pressure, the more you can run the faster you roll on sprint sections ,etc...

    If it is slippery from wet...

    I like to run low pressure in the front , semi low in the back.

    It is dusty and blown out...my least favorite...

    piss on it , drink beer in the shade at the dirtjumps...

    For racing I would say these are the rules but add 5 to 10 pounds more....i give up grip to roll faster
    the trick is ENJOYING YOUR LIFE EACH DAY, don't waste them away wishing for better days

    Um guys, what I think the guy is asking . . .

    is what air pressure he should use in his shock not what air pressure he should use in his tires . . .

    He gives his weight and shock type, but doesn't mention anything about tires, so I'm guessing he wants to know SHOCK air pressure . . .

    You're right. The manual only show 75-175psi. I need my shock performance to be plush & smooth. So what's the right preasure?

    try 120- 140 for your weight maybe even more cause i put about 70% of what i weight in my 5th element.

    never go down to the minimum 75psi, keep it above 90psi. Too low and you risk messing up the shock, and the valving doesnt work properly either.

    or just the DHX?

    what about the Swinger 4-way?
