I upgraded to load range E Carlisle. We traded the trailer before towing enough to comment on the Carlisle tires.
I did convince the manufacturer Nankang to pay me for the relpacement tires after I threatened to file a complaint with the National Highway Safety board. That seemed to get prompt payment, go figure.
My advice is to be careful of the pressure you put in any tire regardless of manufactures recommendations. The tires on our new camper I run 5-7 psi below recommended max.
Temp and pressure are directly related, when the temp go's up so does the pressure. You should always set the air pressure at the recommened PSI, (cold) never try to compensate for the expansion of the tire due to temp, this is a calculation that is done during the engineering process and design of the tire. If you are having Issues with your tires,then the tires may not be the right ones for your application. Running under pressure tires can cause serious problems for handling such as sway, the side walls of the tires can over heat which causes the rubber to exspand thus causing a side wall blow-out and or the bead of the tire could break loose from the rim. You can have all the sway control you want, but it will not stop the side walls of under pressure tires from failing. Please check in to your theory completely for your safety and others.
