You don't mention the manufacture date for any of the tires. If your information on your profile is correct, your trailer is a 2016 model. It "could have been manufactured as early as March 2015 and the tires installed on it could have been made months prior to that, so it's possible that your tires were actually manufactured in 2014. That would make them "pushing 3+ years" since manufacture. That's to say nothing of how the transport driver towed your trailer (underinflated or over speed) when the trailer was delivered. to your dealer or whether the trailer sat on his lot with "underinflated tires" as he dragged it around during repositioning. It's difficult to say that the tires were properly cared for while in his possession and we can't say that they weren't. We just don't know.

You can make lots of assumptions about Trailer King tires, we all can, but none of us can predict that a "known poor quality tire" will or will not perform without incident. For me (your views may differ) it's just not worth the risk for such a small investment to eliminate the problem.

When you "do the math" on buying new tires vs using TK's for another season, realize that Carlisle HD load range E tires are $67 each at WalMart. Someone said that WalMart installs tires bought there "free of charge" (I don't know if that's true) but when you consider that the insurance deductible for most RV policies is $500, the cost of new tires is about half the price of "gambling and losing".....

You're the only one who can make the decision on whether you want to risk TK's or upgrade before something happens.
