    What tire pressures should I have for 2.10 tires

    I generaly have my presures set at 20 in the rear and 30 in front
    I got a couple of snake bites so I increased the rear to 30 Pounds
    I came down a hill that I come down 3 times a week and almost lost it into the trees from sliding
    Amazing what 10 pounds can do.

    I was wondering what pressures you people find good for technical trails (rocks, 8 inch logs) and for steep downhill.
    I live in a gorge so I spend a lot of time seeing if I can make it up a steep trail as well as going down some steep places.
    There are a couple of hills I am so use to that I get complacent and just go down with out a thought.
    Then when I am slideing around I remember I was playing with tire pressures.

    I dont want to go to a bigger rear tire but if I have to I have to.
    Will a larger rear tire cure the downhill traction problem as well as the snake bite??

    Thanks

    In my 2.1 continental Escape and Explorer I am running 32 psi in the front and 35 psi in the rear. I am running them tubeless using Stan's no tubes.
    I may be fat but I'm slow enough to make up for it.

    i ride urban mostly with 2.1 in the bank and 1.95 in the front. i put 60 psi in the back and 55 in the front. i find when i go near 40, if i hit stuff hard i hit my rim, or get pinch flats. i am obsessive about my wheels being true. also, even if i am riding in the woods i keep those pressures and don't seem to have a problem. i am talking about in nc, where there are tons of roots and logs, and it does fine with me.

    The Panaracer Fire XC 2.1 were great at just about any pressure I tried. 29lbs bike with a 230 rider/gear. Didn't have an issue with pinch flats, even at 20psi. I actually think it was just luck.

    Sounds like you have an excuse for bigger tires. A DH casing tire is pretty hard to pinch flat, although you'll feel the weight on the climbs and feel the resistance on pavement. I use pretty big tires for general off-road riding these days, 2.7, and pressures around 20PSI are enough.

    If you get into mud occasionally leave yourself some frame clearance, don't go too big.

    Depends too much on your riding style, your weight and the type of trails and how aggressive.

    I weigh 150lbs, trail is rutted chalk with plenty of flint, some mud areas, and plenty of loose stuff. Mainly ride XC with aggresion and speed on the downhills. Fairly stiff 80mm suspension, so 50lbs front and rear. Next bike same style of riding, far faster downhill speed, and all up weight of 400lbs( Ok its a tandem) This cannot be run at less than 60lbs rear and even at that snakebites occur.

    At 20lbs you will find that the rear tyre will be trying to roll off the rim on corners, and I would not be surprised to find rim damage. If you are a light rider, ride carefully, 30psi f and rear is possible, but hit any lump or hole at speed with these pressures on hard ground and Pssssssss-
