    Singletrack pressures on a 4.0

    What kind of pressures are you guys running now that it's summertime?

    I am running 15psi some Floater 4.0s on Darryls. I weigh 210 geared up.

    I think I could stand to go a bit lower, maybe 12, to reduce basketballing, but wanted to see what some of you guys are doing. Don't wanna experiment with my rims if somebody has already taken the dings for the team.

    Using the search function would be the best way to find your answer.

    15 is crazy high, drop PSI till your floater falls off the rim then add 0.5 PSI

    If you experiment by lowering pressures gradually, your first rim strike will likely be quite soft and not damage anything.

    Approximations are your only available answer.

    Inflation pressure depends on rider weight, riding style, and tire choice ... There is no "One Pressure Fit's All number.

    You'll have to experiment.

    This! I am about your weight as well. I accidentally ran 15 psi once and it was horrible!

    This is the answer for ride optimization.

    You are riding at road pressures. The thump tells you where you need to be offroad. More thumps = more air. No thumps ever = less. Under 2-3 thumps per ride and you are about right. In the end I am only 1-2lbs above snow conditions, generally, and depending on terrain.
    Most people ply the Well Trodden Path. A few seek a different way, and leave a Trail behind.

    Thumps... I would be looking for zero, mine are run just above squirm point and they get a decent workout each ride.

    Theres a very small window of pressure that is the sweet spot, I use a digital gauge before every ride to check im in that window.

    9-ish. any higher and the bike bounces like a beach ball, any lower, I risk pinch flatting. Larry up front and a Vee Mission in rear.
