To resolve this matter I have investigated the current Federal Motor Carrier Safety Administration (FMCSA) testing standards that ST and LT tires must meet to be certified to be sold in the United States.

this is pretty good, but its missing one thing. the tread on a St tire is designed to allow it to scuff sideways easier, as in when you a sharp 90 degree or more turn when backing into a site. a LT tire will be designed to grip the road more giving you higher values on the g pad, not that were pushing our trucks for 1 plus gee's but you want that grip when off road and such. I wonder if there is any testing procedure for Interply shifting?
