    Tubeless Pressure, Rider Weight, Tire Size - POLL

    Let's see your Tubeless tire pressure, your weight and wheel size comparisons. I'll start first.

    25 psi front, 27 psi rear, 175lbs, 26 and 29 x2.25 maxxis ardent UST.

    I'm Increasing my rear pressure to just above 30 because I've been pinching the side wall on jump landings. I started at 22 psi and I've been slowly increasing each time I pinch the walls. Happened a few times so far on different rims too.

    My pressures vary a lot depending on the type of riding I do. I'm about 145 lb. Ride Turner 5 spot with 26" rear and 650B front. Oh, almost forgot. Tire size is 26X2.3 rear and 650BX2.3 front.

    Rooted, technical riding (up or down) - around 20 psi
    Long fire road climbing - 35 psi
    Descending on fire road stuff - maybe around 30 psi
    Smooth hard packed single track - 25-30 psi.

    Bottom line is I vary the tire pressures for the kind of riding I'll be doing. For me, I think of my bike as a 4x4 trail truck that you'd drive to the trails, do some rock crawling or trail running, see what you can accomplish. Then at the end of the day, air up the tire and drive it home again. Sometimes the truck breaks, fix it so that it can be driven home again.

    Great poll, will be interesting to see what others put down.

    I just my first set of tubeless wheels and tires. This thread has been helpful.
    Comas aren't as fun as riding your bike, so wear a Helmet.

    Front 24 psi, rear 25-27 psi on Mavic XM819 with WTB Prowler MX 2.3 UST

    I'm 200 lbs fully geared up.

    Terrain is northern AZ (Prescott) - loose over hardpack (mostly granite), rocks (vary from small to large), dirt. Very dry and dusty.

    Also hit lower desert this time of year with same pressures - loose over hardpack and sandy, not as rocky.
