Hi Folks, our new to us Solitude 310GK came with the Westlake ST235-80-16R, Load range G tires. I'm not familiar with this tire and looking for opinions; ie, are these considered China Bombs?

The tires probably have less than a 1,000 miles on them and look great. If I replace them I would probably for with the Sailuns, BFG, or Michelin XPS Rib, or some other quality tire.
