There are good Chinese tires and bad Chinese tires. Carlisle and Hercules are good Chinese brands - probably better for your spare than your main tires. If you want a tire that you can trust driving down the road, for your trailer weight, buy the G rated GoodYear or Sailun tire as many have expressed very good results with both. I have heard that Walmart usually has good prices on the Sailun tires, I had priced them at a "tire" shop and they were way over priced, they wanted me to buy their Chinese brand tire... I have GoodYear tires on my 5th wheel, but my weights are not as high as yours. If I needed G rated, I would have purchased Sailun tires.
