I did a lot of research on the Triangle TRS02 315 80r 22.5 tires and all the specifications were excellent. After putting them on my 45' Entrega MH and driving 2000 miles I'm super impressed. They are very quiet smooth riding tires. The coach rides way better than it did with the Michelin Energy tires that came with this RV when new. I've owned 7 diesel pushers and have had Michelins, Toyos, Sumotoma, and Hankook. These Triangles are the smoothest and quietest of all. They also run much cooler than the others.
