Without knowing what size tires are on it and how loaded down it is, none of us can say.

Rear, same thing, although at 12.5k gvwr you’re probably 7500 +\- on the rears. 65 psi would be the minimum except in hot weather/high speed high duty cycle I’d want to be wired up more.
Or if you’re running in real cold weather and/or snow I’d want to be a tad on the low side of “perfect” for traction purposes.
That said 80psi isn’t grossly over pressure in the rears for that rig unless it’s basically empty. And even then it won’t hurt a thing or tire wear. Just ride a little more harsh.
