Chinese tires that are marketed to sell wheel packages. But for the price, I boil em off. I dont think there will be any problems. The Chinese can use compounds in the manufacturing process not allowed here, so they may be tougher. Either way, I'll be letting ya know.
I figure it like shoes. Wy buy Nike for $100 to go work in a ditch, when I can go to WallyWorld and get a decent set for $22.99. And they last just as long. With all the tire separations by major US made brands in recent years, the quality issue is falling on deaf ears. Half my Bonneville'* materials are already made in China. :-p
