2 Separate Blowouts on RV Yesterday. Learned Important Lesson on Tires

Personally I think it's more like "modern tires are made of es ech eye tee"

Before I "knew better" in my Navy days I had a car trailer. I used USED CAR TIRES on the car trailer. The longest trip was when I got out of the Navy, I towed a 70 Cuda with a 440 on it, LOADED with spare parts and tools and most of the other crap I'd acquired, from San Diego to the N end of Idaho. Those same tires stayed on that trailer for quite awhile after, and hauled many junkers and jeeps and other "stuff."
