    Tubeless tire pressure survey

    As a new convert to tubeless I was wondering what people are running pressure wise: Please state your weight, tire pressure, and tire size for edumetainment

    thanks

    Weight 200 / 210 geared

    Full Boinger (NoTubes Arch) = 29x2.1 24psi F / 27psi R
    (2nd wheelset Sun RhynoLite) = 29x2.35 23psi F / 29x2.3 26psi R

    Rigid SS (22mm rim) = 29x2.35 19psi F / 29x2.2 21psi R
    (2nd SS/fixed wheelset Kris Holm 40mm rim) = 29x2.4 12psi F / 29x2.4 15psi R

    I am about 160 (170 geared up)-all my tires are ghetto tubeless now

    6 inch full sus
    Front 2.4 Enduro Pro 22-23
    Rear 2.3 enduro pro 27-28

    Hardtail
    Front 2.35 rampage 22-23
    Rear 2.35 rampage 27-28

    Generally about 5 psi less than I used to use with tubes.
    You better just go ahead and drop that seatpost down to the reflector... the trail gets pretty rough down there.

    For UST and tubeless ready tires I use about the same as I do for the same model/size standard tire with tubes.

    When I experimented with DYI "tubeless" conversions I needed to run 5-15psi higher pressure to keep the tires from squirming in the corners.

    Kenda nevegal 2.1 on bontrager race lites converted with stan's kit.
    35 psi F/R,

    I'm shocked to see such low PSI from everyone. At 35psi I can look back and see my tire noticeably compressed. I'd be worried about rim damage, but maybe its just the rocky conditions here in vegas.

    My rims might be too narrow. I have to run better than 28psi in the front to keep from burping... at 165lbs

    I rarely run anything lower than the following:

    Fr: 32psi
    Rr: 35psi

    168 geared

    two differant sets of wheels tried....mavic 21mm wide rim and 23mm wide rim..2.35 nevegals 30 psi f and r i'm surprised at such low pressures also.. ive also used 2.1 nevs in ust ran at 30 psi.... ive tried 26 psi but ng... around here rocks have sharp edges and corners and guarantee cut sidewalls as the rim hits hard on the rocks...

    185 lbs w/o gear
    29er rigid SS - ghetto tubeless - 2.3" WTB Exiwolf wire bead tires - 30/32 psi fr/rr
    26er FS geared - UST wheelset - 2.0" S-works 2Bliss Captain tires - 32/35 psi fr/rr

    I used to run lower pressures (~25/30 fr/rr) but I've crept back up in PSI as I feel like the fast cornering feels better this way. I don't notice any difference in rear wheel traction between the lower and current pressure. And seeing my rear tire less squished makes me feel like the rolling resistance is better.

    If i were to run at the recommended 30psi F/R the bike would be jarring like hell(not that i havent tried). At my current psi, i can rough land a 4' drop and still wont pinch flat my tires. I carry a pump and psi meter during my 1st 5 rides and adjust pressure to check lowest vs most tractable ratio i could get.

    pressures

    I weigh 150 and run crossmark 2.1 up front at 26lbs and ust pythons 2.1 back with 30lbs.I run the same on my hardtail or full susp.I thought I was running sorta on the low side.Much lower and everything gets squirmys and I can feel the tire bottoming out on occasion.I ride mostly hard back,occasionly rocky terrain with some sand.

    Big slacker, how wide are your Bontragers? Forgive me but looking at LMN's post i heaved a sigh of relieve knowing there someone riding at my ballpark psi(thought i was the weird one out hehe)....oh forgot to state i am 135lbs suited up so i guess rider's weight is one of the factors as well. maybe my rims are a bit wider thats why i can run lower psi and not worry about tire squirming?
    BTW rolling resistance is not on the top of my list due to the nature of the trails i ride. Tractability and compliance comes 1st.

    190lbs fully geared and I ride in Phoenix as well, mostly national and the like.
    -819's with Chunder 2bliss tires 2.3/2.2
    -never more than 30 psi, often 25 to 28 psi.
    -I am not a freerider but hit most drops of several feet and below.

    I like with the lower pressures b/c I like my rear tire to conform more on the rocks when climbing the chunky stuff at SoMo and the suppleness I feel on the way back down. If I only rode xc stuff I would use higher pressures for sure.
