A couple things about trailer tires. Years ago ,the US government put tariffs on all off-shore tires coming into the States. Trailer tires or ST tires were exempt. And Goodyear sent all their molds to China.The Marathon tire, for the past six years or so have been garbage. Any tire with sidewall cracking will blow out. It is the sun's UV rays that dry the sidewalls.Do not use Armorall or any other alcohol-based tire dressings on tires because they also pull moisture from the sidewalls. Lucas has a product that actually has a UV-protectant in the product. Make sure you install high-pressure valve stems (brass stems) so that you can run pressures over 50 pounds safely. C-range tires are 6 plies; D-range tires are 8 plies; and E- are 10 plies. For the cost difference, I would recommend running a 10 ply. I personally run Carlisle ST tires on my enclosed trailer and have had no issues. Carlisle manufactures everything from tractor tires to golf cart tires, and are made in China and are a quality product. The new Goodyears, if they are made in the USA, are probably back to being a good tire.
