I look forward to seeing how this ST tire does in the real world.
We have a 1987 Avion 34' travel trailer with 3 axles under it. When we got it 3 years ago, we towed it home 1,000 miles on an older set of Marathons, no issues whatsoever. Then, once I get to reading several travel trailer forums, you'd think the world was coming to an end if you listened to others bash the quality of the Marathon trailer tires. Especially in the Airstream crowd..... those lemmings think that you're not safe unless you get rid of anything but 16" rims and Michelin LT tires. Personally, I have a feeling that a lot of woes were caused by operator problems.
Although I have since replaced my six Marathons with a Commodore brand ST tire, the next time I need trailer tires I will definitely be interested in these new Endurance tires.
Hoping for good things to come.
