To help put things in perspective:
I had a friend who was a tire field test engineer. He was based in Arizona and his test fleets were in that part of the country. He was the only field engineer reporting tire failures (other than road hazard related issues.) None of the other tire field test engineers ever saw one.
He used to call it the "Second Summer Syndrome" - in that the first summer would not reveal any issues, but the second summer is when problems started to reveal themselves.
I can back that up with having plotted tire returns and noted that non-road hazard related failures (what are commonly called "tread separations") peak between the 3rd and 4th year after production.
So be careful extolling the virtues of a recently produced tire. It takes a few years before their true nature is revealed.
