Could you link to the data that documents those statements.

He wont be able to because I just replaced my Marathons with XPS Ribs and there is no comparison the Ribs are much more hefty and considerably heavier.
I fondled both the old Marathons and the new Ribs while they were installing them and there is no way you would walk away thinking ST are better tires.
In fact I kept thinking that the ribs must be the most under rated tires in history or they have a ton of reserve capacity.
I found the same thing when comparing the ST tires that came off my trailer when I was replacing them with Kumho LT tires. The sidewall of the dismounted ST tire could be easily flexed and manipulated with just my fingers. The Kumho 857 has a much stiffer sidewall that can barely be deflected by hand.
Tows in a more stable manner also with the Kumho tires. Part of that I am guessing is the stiffer sidewall controlling side to side flex better.
