ST tires don’t need any particular reason to go pow and I know that from personal experience. I had an 18 K gooseneck tri-axle with 16 inch and the ST tires made it 26 months and I know for a fact they were never run under inflated or suffered any road hazard. Exactly the same experience with my RVs in Arizona. I never had ST tires last longer than 50 months and the trailers were only used for about one month out of those 50 months and stored off the ground and covered.
I use nothing but LT – E tires on my trailers and the problems are gone. Craig
