We needed to replace five tires on our 35' Winnebago Adventurer Class A motor home. After research, and much hesitation, we chose Sailun brand tires, from China. Installed the price was about $1,000.00, well below the "big name" RV tire prices.
We left the Miami area two days later, drove to L.A. and San Francisco, then returned home to south Florida.
The tires handled as well as the replaced Goodyear tires, were problem free, and seemed to be quieter then either the Michelin or Goodyear tires.
Just over 6,000 miles is not much to make a firm judgement, but so far, we are very happy with that brand. The trip was done mid-winter, but I would not expect higher road temperatures of summer driving would have made any difference in the handling, or noise.
