In my opinion, I believe a lot of the China Bomb posts lately are caused by using tires that can't handle the weight. (Maybe the user is overloading the TT, maybe the factory installed too low of a load range tire) Since most of the TT's come with the china made tires, there are a lot of them out there. That means a greater number will fail when you are talking percentages. When they fail, all people hear are "change to good year endurance." When they replace tires, most go to load range E and above and no other issues. I'd be willing to bet that the load range fixed the issues and NOT the fact that it was a Good Year endurance tire. But....everyone has their own kool-aid to drink.
