Most Carlisle tire problems were prior to about 2014, they have gotten mucho better with the last 2 tire models. The Radial Trail HD has gotten very good reviews. Not to say that they can't have problems, ANY tire can!!
I have had Marathons on the last 3 trailers we've owned. US made, New Zealand made, and the latest on our Timber Ridge are (OMG) Chinese!!! None of these had any road problems, have had 2 tread punctures in the woods (usually turning around in a dispersed site), not a tire problem!! Present ones have just over 12K miles on them, and are aboot 50-60% worn and are just turning 5 yrs old according to date code. They have not had any problems in 4 yrs.
But after saying that, I just purchased 4 Carlisle HD's in E load rating due to the wife's urging before a 6 wk, 3000 mi summer trip. By age the GY's need to be replaced to forestall problems, and then I can worry about problems with new tires!!!! I felt that the Carlisle's were a better buy, with slightly deeper tread, and same or better reviews than the GY Endurance.
Bought at Discount Tire, they will almost always meet another price, either store or on-line. Got a great price, and am having local Costco mount and balance with HP stems for a much better price than any of the local tire shops including Discount. Just wish they carried the Carlisle or Endurance rather than the ones they source and sell.
