You are correct on the load rating for the LT/235, I was quoting the weight capabilityof the LT225. I'm no tire expert by any means, but it seems like if there was away, they would have already come up with a good tire for RV trailer applications. I suspect that the problem lies in the sidewall construction. To carry the additional weight requires beefing up the sidewall, but then you run into a problem of dissipating the heat. Boost the air pressure up to 110# and you cut down the sidewall flex and heat, but you give up the smoother ride. Maybe if they went to a 17.5 or 19.5 tire they would solve the problem and the cost difference would be minimal.
