    Tire pressure

    Two attempted rides today, two separate tire punctures. I hit a smashed Snapple bottle and did the walk of shame home with a busted tire (co2 inflator was out)...
    What pressure do you guys ride at? I think I may have been riding too stiff at 110 psi. I am 235lb.

    I ride at max (120 on my road bike) at 220ish lbs. CO2 sux as once it is gone. it is gone. Pumps go on forever. And I've had 2 flats in one day (last weekend for instance). It is all part of the game.

    You might want to go up to 120 psi.
    I carry 4 spare tubes.

    Tire pressure has little to do with it when you ride over a broken bottle.

    That said, you max pressure is indicated on the side of the tire. A higher pressure gives you less rolling resistance, but a harsher ride. A lower pressure gives you a plusher ride. Too low a pressure might result in an increase in snake bite flats.
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

    I ride at the max presure or 5% above always have and since I lost a pile a weight have NOT had a flat . But at 370 lbs I had 4 or 5 flats last yr ! after I got below 250 # no more flats . I ride a lot at night also and run over a lot a crapola even with great lights you stil don't see it all at night ! If your not a mega clyde IMO say below 250 # flats are just a matter of luck ! BUT when your in the mega CLYDE rage IMO you will get more flats ! I know guys break spoks and bend wheels but even at 370 # last yr I didn"t but I bought bikes with very good wheels recomemned by my LBS

    I did have to have a front wheel trued once MY FAULT I hit a pot hole not pay attention .

    weird... but in fact you'll have lower rolling resistance at a lower PSI in real world situations (non smooth roads)...

    What size are your tires?
    My weight is 250 and I am running the 28mm gatorskin tires at 100 psi - in comfort and without problems.
    The width of the tires is an important factor.
