I have 406 mm. Stelvios on a Dahon Hammerhead & rode several hundred miles before getting a puncture on a canal towpath (a frequent source sadly, but in Summer, the local one is what I imagine the Amazon to look like).
On a Brompton, they're like having an extra gear, much faster than the "normal" tyres, but more prone to punctures certainly.
To save time if I'm riding to catch a train, I always carry a Stelvio + inner tube, then repair whatever was on the bike at a more convenient time.
My wife has Kojaks on her bike, & they do seem fine. I really like the bald look, as it's easy to spot any embedded sharp stuff. However, 349's (Brompton size) are twice the price of Stelvios, so I'll hold off for a while :-)
