I will state again, there is no down side to running the rear tires at max psi. Any TC will heavily load your rear axle. The added safety of running at max psi is well worth a “harsh” ride (which is very unlikely with a TC in the bed).
If your are referring to the maximum pressure listed on the sidewall of the tire, you're wrong.
I'm not a troll. I have just read through many pages of tire care and maintenance published by Firestone, Goodyear and Michelin.
All stated that the listed pressure on the tire sidewall, is NOT the recommended pressure for the tire in question.
