Based on the RV in your signature line you have ST225/75R15D size tires. The best ST tire available in this size is easily the Maxxis brand M8008. The Carlisle are chinese made and will not give you the same service. Since you are in a jam on leaving ASAP it may be the best option for now, just know that you will have to revisit this issue soon. I just checked the Carlisle web site spec charts and they do not list a ST tire in load range D that has an 80 psi rating. Only the E rated tire has max psi that high. Running an 80 psi tire at 50 psi can lead to overheating of the tire and lessens the weight carrying capacity listed on the tire. If you must do this trip with this tire I would recommend running higher pressure (65 psi) even if the wheel is not rated for it. There is less risk at running over the wheel rated psi than running the tires 30 psi below max. The best solution is to check the wheel for the rating and run the proper sized tire at the recommended pressure. The tire store is not doing you any favors on this one IMO.
