I just ordered a new Cyclone 3800 toy hauler and it comes with Chinese tires. A buddy of mine said to get rid of them RIGHT AWAY and buy American tires. He said 5 of his 6 tires blew out or came apart in less than 10K miles. He is anal about keeping his tire pressure correct so there was not an issue of the tires being improperly inflated. Anyone have good or bad to say about the stock Chinese tires? Should I have American tires put on at the factory while they are building it or just stay with Chines tires?
