I did the axle mod and put 14" wheels with Taskmaster Contender TTT868 205/75-14 on my Coleman Sea Pine. I've pulled it up the Jeep trails in CO to go off-grid into the wilderness archery elk hunting. They have held up great! Biggest thing is a good tall sidewall. I have an electric tire pump so I can deflate my truck tires and camper tires some to allow for more cushion while traversing rocks/ruts/boulders along my routes. On the highway my truck doesn't even notice the trailer behind it. From NC to CO I held about 10mph over the posted speed limit. I also make sure that at a mid-point gas stop I re-grease the wheel bearings.
