    Is there somthing wrong with this?

    I've got inferno 23's with stans strip running Schwalbe racing ralphs and they are terrible.

    No traction wipped out 3 times today.
    They are ran at around 25 psi.

    I would rather run my nevagals with Tubes at 40 PSI than this.

    I weigh 220 lbs, does this have anything to do with this?
    Is there a point where if you weigh above x amount tubless doesnt work?
    OR is it my setup not being "True Tubless"?

    Being use to Nevegals, and at your weight you may need to use more pressure and learn how they handle. The RaRa does not handle the same or have as aggressive tread.

    The trouble with common sense is it is no longer common

    I just came back from the garage and pumped them up to 35 psi.

    Its like at the lower psi the whole tire rolls on its side wall and I get no traction.

    Tires should have weight ratings.

    Before the nevs, I hate slant six's which were terrible for my weight.
    And after comparing the slant six's and the racing ralph's they look very similar.

    I'm going to a different traill tommorow that's not so technical so maybe ill get a better feel for the.

    Honestly, 25 psi at 220 lbs is a bit optimistic. Just up your pressures until you feel a compliant ride without the roll-out issues.

    Take a pump with you and modify your settings as you go.
    Please donate to IMBA or your local chapter. It's trail karma.

    Those tires are fast, but they may not be aggressive enough for your style of riding and terrain. If you still are washing out go to a Nobby Nic on the front. More grip means more curve speed and almost as fast in the straight-- just not.

    I def. Have the " roll-the-tire-into-the-lean riding style".

    I have a nobby nic up front RR in the rear.

    Both were acting up.

    I put some air in the nobby after biting it hard. and it seemed to be fine after that.

    Im really afraid the RR just doesnt have enough tread on it for me.

    It keep washing out.

    It doesn't help that I changed from nev's to these.

    Also the nobby nic seems like it should go in the opposite direction than the suggested direction on the tire.

    RaRa's can definitely be a little skittish. If you're 220, try running them around 29 PSI in the front, and 32 in back. Then just remember they aren't going to hang on as well as something like Nevs. They do pretty good straight dirt that's semi hard pack, but if you put a sprinkling of rocks across the top, forget it. They are just a really fast racing tire, meant for really fast XC racing trails.

    One of the spot was a tight downhill switch back with a light layer of fine gravel.... thanks for the warning about that. Seems like this is the type of tire you put on just for races and when your extremley confident in the trail

    I think part of the problem is the rims are too narrow. I've run Slant Sixes on 30mm rims at 30 psi and they've been great... I weigh 255.
    I build Inferno 27's for everyone as I feel the 23's are too narrow for the 2.25 and up tires.
    I like turtles

    I came across this Tech Tip regarding Tire pressure..,

    To determine a starting tire pressure when running NoTubes tires, use this simple formula.
    Rider Weight in pounds divided by 7 = x
    x - 1 = Front tire pressure in PSI
    x + 2 = Rear tire pressure in PSI

    220 / 7 = 31.4. So in your case, 30.4 PSI in the front, 33.4 PSI in the rear.

    Hope this helps!

    Nice ill try that tip.
    I just got down riding through the neighborhood with them up around 40 and they felt way better.

    Some confidence is getting built there.

    This psi thing might be the reason why I didnt like the s6's.
    There is a huge lack of side knobs on those though as well.

    It worked... these tires are insane!
    This time I almost wiped out because of too much speed in spots I usually dont get.
    Thanks for the help!
