Yeah, we're in NYC. I was riding a well paved road in almost every case, perhaps a small pothole but nothing major. The back tire just keeps going flat. There is not contact with the frame. It's hard for me to fathom such bad luck--there have been no incisions in the tires in any circumstance--I just wonder if the physics of the frame might in some weird way cause undue weight/pressure on the back tire.

Does anyone have suggestions for good (yet affordable) road tires to buy that might offer more protection? I have IRO 700c's.
