Before you buy Sailun's you might want to search the Montana Owners site for other comments; there were some negative ones a couple of years ago. I had Sailun's and didn't have any problems but recently changed due to age (5 years) and went with Carlisle this time. Initially Sailun's were made in China, now they're made in Vietnam. China moved the factory due to trade sanctions I think. Not sure if there's any quality difference. I also use Discount Tire for service and they recommended the Carlisle's (also made in China). I second getting G rated too.
