Based on what evidence? I know that people think that low pressures allow the tire to flex around an object better than high pressure does but, in practice, I’ve never found tire pressure to have much effect on flat frequency. I have bikes that run 110 psi to 80 psi to 40 psi on my mountain bikes. All of them have gotten flats at some point with about the same rate. The mountain bikes experience far more flats than my other bikes but they are ridden in places that are more prone to objects that can puncture the tire. Most of the time, that’s goatheads but I did flat this last week on a prickly pear cactus spike.
