    What tire pressure do you run.

    So I'm curious on what some of you guys run for tire pressure and what size width tire.

    Im runnning 50 psi with a 2.0 tire. After My Seat purchase I am going to Go to 2.2 or 2.3 tires.

    My rear is a 2.2 and I run 45-50 psi. I run tubes so I ride high pressure to avoid pinch flats. Someday I may try tubeless...just haven't made the jump yet.

    Around 6'5", 250. 2.2s w/32 rear, 26 front. Tubeless.
    On singletrack.

    Are you on the trail with that much pressure? Or Roads?

    I wouldn't have much traction, with that much pressure. On dirt hills in my area.

    Me personally, yeah, I'm on trails. Dirt, mud, rocks, and roots. Traction not that bad. I could probably come down in pressure at this point. I've been running that pressure since I was 320 pounds. I'm down to 275 now so I can probably start lowering it some.

    Sorry, I was responding to the 208Ryder. Yours seems a little high also. I have been running around 35-38 psi with tubes in the rear previously. No rock gardens, but plenty rooty trail.

    I run 30 - 35 with a 2.4 with tubes. Also want to switch to tubeless, but slime tubes have held up until now, so I'll wait till money is available. The desert is brutal on tires!

    6'3" 200lbs, but was 235.

    rim size and tire size all has to play into it... a 1.9x26 will need a higher PSI than a 1.9x29 will and a 2.5x29 will require even less...

    some tires will require less air and others more just based on how they are made.

    I found around 12psi on my 4.7x26 on the 80mm wide rim to be about right... 2psi more and it was to harsh... granted that is obviously a fat tire and I'm riding rigid.

    it's all about air volume, how much you weigh, and how you ride.

    you'll also find tire psi more important on rigid bikes...

    the best way is to pump up before EVERY ride and monitor the pressure... if you are bottoming out on the rim you need more pressure, if it feels like the tire is rolling out from under you then you need more pressure... so really it's a game of experimentation :-/

    2.10 both front and rear @ 35 psi. Tubes on both ends. I ride single track, fire roads and lots of technical trails (roots, soft sand, etc...). Only pinch flats I have ever recieved were from the tarmac at the end of my ride.

    The lowest I can go without pinching, then a couple more PSI for good luck.

    Sorry for the delay. It was the weekend and I was out riding and having fun.

    TO answer you question I am 6'3 345#

    I figure the higher pressure is better so I don't hit the rim or pinch the tubes. Even at 50psi they still flatten out a little, so the tread gets flat contact.

    I ride both street and single track. I did notice though yesterday that with it that HI on the trail it did feel a little loose. So I might let it down to say like 40-45PSI for trails.

    6'0" 230lb with gear. Currently running tubeless 2.4 Purgatory front at 32lb, 2.2 Captain rear at 34lb. I may lower the front pressure just a tad after rides this past weekend.
