"Tubs puncture more easily than good, properly installed clinchers. Anyone who claims otherwise is talking nonsense."
I disagree. Discounting compression puntures which I feel tubs deal with better I have still had less punctures with tubs than clinchers. There is no reason to say so. The same maybe be but as my tubs were always cheapies or second hand ones whereas my clinchers are decent ones it could be that there is my answer.
Not sure I follow you on that one.
I should qualify this slightly as I wasn't thinking of like for like exactly. Most tubs don't have any real puncture protection. Not surprisingly, they puncture quite easily.
Where I agree with you is that a blow-out on a tub is safer than a blow-out on a clincher, especially if it's the front tyre, but you shouldn't get a blow-out on a front clincher if it's been fit properly, the tyre is in good condition, and you don't drag on the brakes on long descents.
I haven't tried them, but tubeless tyres on the new-ish wider tubeless rims seem to have both the ride advantage of old-fashioned tubs and the puncture protection of the best clinchers. Or so I hear from friends in the States who ride them. But it may just be they've been taken in by the marketing tosh. I suspect they've never actually ridden on tubs to begin with.
