I gave up on trailer tires circa 2007, using appropriately load rated light truck tires instead, and unsurprisingly tire failures disappeared (except for that one somewhat infamous event on the way to Hallett...but the root cause of that incident is unknown as all evidence was destroyed in the incident so...) Anyway the Endurance didn't exist then, but it appears to have bridged the gap between the run of the mill trailer tires and real tires.
