PSI Advice for Toyo 285/75-17 ATs

I put on these tires early this year, and they have been great so far. I am running 55 front 45 rear empty and they are wearing even. I have to tow a heavier load this weekend, and I know I should bump up at least the rear. I was thinking about 70, any advice ?

What does the sidewall say? Depending on how heavy the load I would probably run 70 in the rear and 60-65 in the front.

Mine are 285/75/18s, but I have been expermenting a bit.

Les Schwab recommended 60 psi all the way around, and that is where they aired them up to. That pressure seemed to handle my 5vr very well, but hit a bit hard on the rearend when empty. I now run 60 psi in the front and 50 psi in the rear while empty, tires all look very equally loaded. when I hook up to my trailer I will bump the rears back up to 60 psi.

80psi, but I didn't think I need to go that high.

Thanks. I think I will try 70, 10psi less than max.
