trailer wheel weight rating/compared to tire psi rating?

People make too much fuss over the tire scrubbing. The only time the tires are subjected to much scrubbing is when you are in a sharp turn or backing and you are going slow. 98% of the time they are running straight and not subject to scrubbing.

When I have to back into a site, the tires on my 3-axle 5er do scrub but so far, I age-out the tires long before they are worn out.
