Underinflating will break down the sidewall before anything else and that is where the majority of failures happen. Under inflating = more rubber on the road = drag =equals heat = excessive wear. Makes sense to me, but I'm not an automotive engineer. I've always gotten more that the expected life from tires simply by running them at max recommended pressure.
That said, I check tires on both truck and trailer before every trip and inflate to max pressure(cold). it works for me so far.

I agree with you. I look on the sidewall of the tire and use the recommended tire psi.
