I still think after running both XPS Ribs and R250s, that the R250 at 50 dollars less per tire are the way to go. The R250 out weighs the rib by a few pounds due to the extra sidewall protection and a Nylon cap ply that is not listed in the rib construction. I have been getting the best mileage ever since installing the R250's. Like the ribs they hold their inflation pressure over a year without adjustments. Trailer stability is great with both. One poster will be along to point out that I have 5200 axles not 6k. He knows however I run inflation at 71 pounds to match the actual weight, so to him I say get a life.
We tend to do the 1650 mile to Arizona or back in 3 and half days and I never worry about tires. 502 miles from the East Valley to Bakersfield in one day with 90 plus temps on I-10 is a good test. Infrared readings show the trailer tires run cooler than LTX M&S on truck. 119 vs 125 degrees.
Did one trip on I-10 a couple years ago with 40 MPH wind out of the South most of the day. North shaded side tires were warmer than the sunny South side tires. Took a few minutes to process the fact that the wind was loading the down wind tires considerably more than the up wind sunny side tires. Dynamtic loading that would be very difficult to measure.
That is my story and why I believe in steel carcass tires for trailers that want to see America. Belt and suspenders. Having grown up in a family business and worked in the company that included Firestone and Eldorado tire jobber, I learn early on the importance on quality tires.
