There is only ONE way to figure ideal tire tread meets the pavement.
Tire. Chalk. Pressure. Test.
Look It up on youtube or the internet.
Everything else within the minimum maximum is
religion,
speculation
and
'my dad ran xxxpsi in his 65 gto' ghost stories.
Your more air gives it more time to go flat theory isn't conclusive. More psi might make the hole theoretically 'bigger' as psi pushes out more air...per psi.
What doesn't leak at 60psi may leak at 75psi.
My 3/4 ton truck with michelins runs at 38psi.
My neighbor with the same tires runs his at almost 80psi.
His truck rides like shit.
My truck rides like a dream.
I'm not really interested in tire longevity.
Mine don't cup, his doesn't run the center out.
I did the chalk test
He read the door frame and sidewall.
