No its not nonsense, Mr Pooch Screwer. Not getting flats is a matter of keeping your tires properly inflated, and luck. I've ridden around on the same pyramid 700x25s for hears with harldy any flats, because I keep them inflated properly. Sure, your likelihood of getting flats may reduce to near zero, but these tires cost $100!!! If a bike that is not worth that much on its own!!
