So, you are stating that trailer tires are the same quality as a P or LT tire? No way you will convince me of that. I am more diligent about checking tire pressure on my trailers than my cars - tested every trip. And I won't run ST tires any longer than 5 years from manufacture. Yet I still have easily had 5 times the number of tire failures on my trailers than I have on my personal vehicles. Plus, I likely put 30,000 miles/year driving cars/trucks vs towing maybe 8000 miles in a year.
Coming home from the lake/camping yesterday I saw at least 3 trailers on the side of the road with tire issues, but I don't remember seeing a car/truck with the same.
There is NO WAY quality is the same between the tires.
The quality may or may not be the same but the number of observed failures on trailers doesn't directly prove the point. Trailers are exposed to more hazards than the cars/trucks due to their wider track and inside track on corners. They are less likely to be noticed if a leak develops since you cannot feel the low tire. They are also more likely to be overloaded than most vehicle tires.
