When I first bought my road bike with 23 tires I got a flat within two weeks. I am 150lbs and was running around 80psi. Lot's of people prediccated I got a pinch flat ( two snake bites ). Sure enough when I inspected my inner tube later it was a pinch flat. I agree with others you should be riding with a lot more psi.

I now run 28 Continental Grand Prix 5000 at 100 psi. No more pinch flats. I wish I could say now more flat tires. lol
