From my anecdotal experience most blown tires happen to those who don’t trailer often. Otherwise I can’t explain how I had only one flat (not even blown) tire in 20 years and estimated over 100,000 miles of trailering all over the hot western roads and mountains. My trailer gets driven at least once per month on average. The only maintainace I done was replacing the tires every 5 years or so.
Hope I didn’t just jinxed it.
