OK, boys and girls, I took this picture in Lost Wages last month of a semi trailer next to me at Circus Circus RV:



Then I turned around and took a picture of my trailer tires:

You really need to learn to chew gum and think. There are many other aspects of tire friction, construction, compound, air pressure and many other items. The same engineering goals still stand. Just like the last 30 years.

Really, so answer me this if construction of the tire is so important to where it is used??

Semis, buy NEW tires for the steer axle, as required by law. once the tread gets worn, those casings are caped, and likely first placed in the drive axles for a couple cycles. Then after several cycles, they are capped and placed in use as trailer tires. All with the same casing construction, just a change in tread design!
So those of us that run LT tires are doing the same a Semi owner/drivers.

You really shouldn't compare commercial trailers and tires to RV. There are significant differences. Take a look at the semi-trailers frame and suspension carriage. They are constructed out of High tensile steel. They have the material and design to withstand the forces from the load and turning. The RV frame is mild steel. It will bend until you exceed the elastic limits. The RV design uses all of its components tolerance and bending to absorb the forces when cornering. The axel will shift then bend along with the tire forming z shape to get around a sharp corner. The semi will slide the tire long before much bending happens.
