New tires, what pressure do you run?
After nearly four years or rolling on the factory China bombs, I had some Goodyear Endurance ST tires installed.
I had a good conversation with a buddy about tire pressures. I always ran my China bombs at max sidewall pressure, 80psi. He suggested running at the appropriate pressure for the load. I have never weighed my trailer but we went through the exercise anyway. My trailer max gross weight is 8500 pounds, with four tires that gives us 2125 pounds per tire (disregarding tongue weight). My tires are ST225/75R15.
50psi tire inflation gives me a capacity of 2150 pounds per tire...more than enough. I’ve probably never towed at max gross so that’s still pretty conservative.
Running the tire pressure at closer to the recommended pressure should help the tires last longer and save some wear and tear on the camper. I’m going to tow at 50psi for my 1st trip of the season soon to see how it feels.
What do you all do? Max pressure, or adjust for loading?Eric & Sandra
