Load and proper inflation is the way to go. There is a reason they make load/inflation chart for every tire.
This is exactly what Sailun told me when I inquired on the appropriate psi to run out ours. In fact they provided a bit of education to the different wear problems from over inflation (not just what you would expect from more wear in the center of the tire). The psi I run is less that the OP has his set at.
An FYI, I put Sailun on ours two years ago. Balance and the fifth wheel had factory shocks on each tire. A year ago I replaced the shocks with Monroe Gas Magnums when I put on a SRE4000 equalizer. Axle max is 6000, weight on the two axles is about 11,000 lbs. We haven’t had anything inside break and not one door or drawer opened since the Sailun s were installed.
At the time I was replacing two year old Marathons, GY had just come out with the Endurance so very little feedback on them. Plus, I wasn’t thrilled to add to GY pockets after they profited from selling **** Marathons to thousands.
