At 100 psi, the tire is rated at 3550 lbs load capacity, so that makes the 7,000 lb axle rating. So, as long as you are at or over that number, you are getting the full capacity of your axles. I usually try to get close to 110 psi, but as long as we are over 100 psi in the morning when pulling out of a park, I'm good with that.
