What do we consider properly reported incidents? Officially registered accidents? race crashes? If so, then there are very few tire incidents overall. If we however accept anecdotes, there's plenty to be found with a fairly short search of the other cycling forums.

But then there's the substantial mitigating factors. I don't understand what you mean by this and what is considered substantial?

In any case the safety margins are way too tight. With hookless rims it would seem that a difference of 1mm in tire width is the difference between make it or break it. A 10% pressure safety margin is something you can exceed when you go from an air conditioned garage to ride in hot weather on hot asphalt. Especially if your pump gauge is inaccurate. Also, that 5 bar max pressure is too low for heavier riders in any case.

Just compare against the amount of leeway you have with hooked rims in both tire size and tire pressure.
