Yeah, I tend to keep 'em high, I'm no light weight. It's an interesting chart, I like his take. I've seen others not as good. Seems though, that lots of writers lean towards the whole avoiding the over inflating theory. Sound theories, I've experienced plenty of pinch flats, you know "snake bites ".
I can see it more on a +32mm tire or extraordinary conditions; sandy pavement, lots of pebbles. small bumps or washboard surfaces. Can't see the load-aspect, doesn't pertain to other vehicals anyway.
I max or close to max them and have never had tires within 5lbs. dif. either way cause problems.
I get very few flats and have yet to bend a wheel other than REALLY goofy times as a younger man.
