As a late-in-life arrival to road bikes, after the better part of 4 decades on MTBs, "max pressure -5 psi" seems awfully high, especially for 1.95"-2.1" tires.

^ This. Saved me some typing.


Lower tire pressure allows the tire to deform around a potentially puncturing object, but with that kind of cut, I doubt it would have mattered.

It think you probably hit something that cut it. I'd expect a failure due to a flaw or even something like a way overinflated tire to be more of a tear in the outer layer of rubber.
