2013 Heartland Bighorn Tires Problems

“We purchased our 5th wheel nov 4, 2012 - experienced our first tire bubble 12/10/2013; second tire bubble 12/19/2013. We had been advised by several Bighorn owners that they replaced their china tires prior to hitting the road, but casual inspection on my part indicated that the power king tires installed were sufficient for the application - I was incorrect. There are numerous posts online that these tire mfg misrepresent their tire's adequacy. …”

Then two weeks ago we were returning from a trip to the texas hill country back to the houston area when the second blowout occurred. …”

Checking different sources on-line revealed that tomax tires on Heartland rvs are a know problem. My good friend has a 2012 that three of the four tires came apart on the road and caused major damage to his rv. He had to buy 4 new tires while sitting beside I-95. I asked Heartland to check mine. They sent me to tire kingdom (who sells the tire) of course they said because nothing had happened yet they could do nothing. I am very concerned. …”
