Many trailer tires are probably produced in the same factory in China is a safe bet, but they are not all of the same quality. For example, if you were to buy an off brand trailer tire by Westlake, Tow Master, or haul master, they have the exact tread pattern as a more expensive Goodyear Marathon. But, Goodyear has stricter guidlines used in the production of their tires and use a better rubber compound so it is probably a better tire. Now that being said, for the last seversal years I felt like the blow out king. I bought a set of Maxxis tires that are load range E instead of the "D" that my rig requires and have not looked back. So far, they seem to be the best. My set was produced in Tiwan and do have a completely different tread pattern. Hope this helps.
I had a ton of problems with the Goodyear Marathons 9 and they were being built here in the USA then and being they are real proud of their tires I went to China tires ( cheaper and can go up a load range ) a load range( from E to G 8 ply to 10 ply ) above what was on the 5er and not many problems since. I think the thing to do is go to a better load range and I watch tire pressures like a hawk. I was in the tire bidness and can spot a low tire by nature. I don't drive over 62 mph ( best fuel mileage ).
