I ditched the no-name tires of the same size on my boat trailer, and just finished a 1000 mile round trip with the Endurance.
I had terrible luck with Marathon's, and hope the Endurance is better. They did very well on my last trip. Honestly, I can't believe how much better the trailer pulled. I hope that they continue to live up to my expectations.
