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.

Two of my riding friends have had SIX Flats Each on the same ride.
I carry 4 spare tubes.

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.

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.
