^A truck tire at 4 corners of truck, with free running front, and differential on the rear is a different scenario than a tandem axle trailer. The light duty ST tires I use have much softer side walls than the HD J-rated tires you are using. An ST trailer tire, properly sized/rated, on tandem axle will perform best, least side scrub/sway, run coolest, at full sidewall capacity.
My ST tire edges, wear faster than tire center, at full psi, due to scrub. In any case, mine will age out (8 years of use now) before wear out.
Roger Marble, a very accredited tire engineer, former member here, has discussed ST tires in length on tandem axle application, and agrees with my thought on this.
It makes for good discussion, and many have differing opinions, concerning pressure of trailer tire, not truck tire pressure. You and I are not going to ever have the same opinion, partly because of the difference between our rigs, and the tires required to support them.
I value your opinion, recommendations most things, as I hope you do mine.
I know that JIMNLIN, a commercial hauler, for many years/miles somewhat agrees with what I am saying. I have always valued his opinion, concerning tires.
