While I agree with you 100%, apparently the vehicle mfgs don't since the godd@;);$mn TPMS indicator is set to trigger at barely under 80psi on my last 2 new Ferd 250s.
I do always run full psi in trailer tires, and in the op's case, I'd run 80-90front and just air up the rears to the max when loaded at 11-12k rear axle weight.
Don't let engineering by lawyers fool you.
What happens when a guy loads up his F-250 to the RAWR and blows a tire from under-inflation? On a truck with TPMS it is the trucks fault right?? From a warranty and liability standpoint it is easier to set the TPMS to 75 psi than it is to expect the drivers to do their due diligence and air their tires up when needed.
TPMS is now set to match the max pressure needed for AWR, which is BS for most users but oh well... lawyers and their effects on our life.
