But I digress........I remember when I was a kid, this wasn't a huge issue. There were people that routinely had tires that were ten plus years old and did fine. Of course, lots of factors have changed, too including car speeds with the advent of everything having an over drive transmission, so that's one thing. It could be too that since the whole world wasn't "as connected" you just didn't hear about the many tire failures as much too. I wonder though, about tire rubber composition. Has it somehow changed for the worse? I'd sure like to think it's improved, "supposedly" like everything else.
