Anyone ever use foam inserts that go between the tire and tube, like Tannus Armour? It looks like a good concept, but they're kind of expensive for a piece of foam.
You are not getting pinch flats above seven or eight PSI. Five PSI is getting into the pinch zone. Accu Gauge makes a good low PSI gauge that's under $10 on Amazon. I like dialing my pressure to the half inch but I do like to ride at low pressures.
Can't comment on a tire mousse but have you considered tubeless? Going tubeless fixes most flat issues. I was surprised but the number of cactus needles I had in my tires when I pulled them off. Pulled the needles, swapped the tires front and back, filled with Stans and still running problem free.
