When I replaced my OE 205/75R15 LRC I put Carlisle 225/75R15 HD on my 26' Koala trailer, and run them @ 65 psi. My trailer is a lightweight trailer, and the tire dealer installed LRE instead of LRD as I ordered, but they were already installed so I kept them rather than reorder the LRD/s as we were ready to head west.
We put about 7500 miles on them, so far, to Albuquerque and back to SC.
Being as though they are 10 ply tires, and are a bit stiffer, I get a bit of sway due to the wear in the traffic lanes from the heavy trucks, but overall I'm pleased with them so far. I think it's a good choice in a tire.
