Couple comments...
One, I run nothing but Michelin or Firestone top tier tires on everything from my wife's van to my pickup truck to my Focus to my gooseneck traliers. Good rubber equals no issues. You buy cheap foreign rubber, the chance of failure increases...
Assitionally, I never use push in rubber stems either (on any tire/rim. Always screw down metal valve stems, almost always Milton. The only deviation from that are wheels with TPMS monitors built in.
Secondly... I never an 'engineer' designed any RV from the almost universally shoddy way they are built. Thought it was a shoemaker instead.
