    I've been riding trial for about a week now, but I'm still not sure
    about tire pressure. I have the creepy crawler tire and I'm running it
    the lowest I can with out bottoming out the rim. Is that going to give
    me the most bounce or is there some kind of happy medium where you can
    just get a really good bounce. I need the bounce because I'm not very
    big so to jump up anything high I have to get the pre bounce. Thanks.

    that's the front; run 150 in the rear.

    OR, use the SEARCH function, since this topic gets posted almost
    daily!

    I have just started getting into trials myself and have been
    experimenting the last few nights with this.
    I had it too hard when starting so let some out, then it was ok...
    thought then maybe i could get more bounce so let more out - ended up
    bottoming out the rim... so put more back in, up to 25psi.
    When riding last night with 25psi i let a bit more out and its great
    again.
    I'd say between 20psi and 25psi... 20 bottoms out and 25 is too hard.
    Hope that helps.
    Peace.

    *EDIT*
    I'd say closer to 20psi... Just remembered i had let it out to just
    under 20.
    Maybe give 22a try and see how it goes for you.

    Why don't people just post the answers to questions like these rather
    than spending time typing out ''use the search''?

    It might be annoying, but how are new people gonna know this??

    I have my tyre as low as possible, without risking damaging the rim -
    you need to work out the right PSI for you by yourself.

    Please explain how you plan to do this on a
    *_-UNI-_*cycle.

    It's hard to not ask what all the other people are using isn't it.

    Let me assure you the reason you cant jump onto a picnic table is not
    weather you have 25 or 35 psi in your tire.

    Thanks to everybody that helped me out, I'm sick of these people saying
    using the search as well. But I'm still curious as to why the first
    replier was saying 100 psi when everybody else says 20- 30?

    Well if the psi doesnt matter how do people just jump onto tables. I
    mean I can't even jump straight up onto a table without a unicycle. I
    always thought people used the bounce to get up there.

    A combination of technique and tyre pressure, probably more of the
    technique & practice.

    No matter how bouncy your tire is, you'll never jump higher with your
    unicycle than without.

    I can jump higher without my unicycle than the world record for jumping
    with a unicycle. I can only do 75 cm with my uni.

    If you cant jump onto a table without a uni, I wouldnt plan on doing it
    with a uni any time soon.
    Being able to hop that high takes practice. Your muscles with grow
    stonger the more you ride.

    The more you work on your hop = The higher you will be able to hop

    Personally I ride with a pretty high pressure, 25-32(trials tire) I
    only weigh 125. I ride my freestyle street tire at about 45-50 or
    higher. Also I dont prehop. I compress the tire with leg pressure not
    the impact from a prehop(an overrated technique).

    Tire pressure is more of a comfort preference than anything. Of course
    you want enough so you dont hurt your rim or tube, and not so much you
    hurt your feet legs and privates.
