Not sure of the point of this poll. What use would these stats be to anyone?
I have never flatted, ever, not once, while riding a bike, since I started riding in the 80's *knock on wood* Have had several flats just from bikes not being used for long periods of time, but never while out riding.
I just got back into cycling this year and have ridden several hundred miles on 26x1.5 Serfas Drifter tires and have not flatted yet. Just got a new road bike last weekend with 700x25c tires, so who knows what will happen with that one.
