I've heard this, but I've never seen a tire fail that was run on a dyno. In fact, we took a tire with a plug in it and hammered it intentionally on a dyno and couldn't get it to fail. Of course, I would never recommend doing such a thing...
Rarely is the question stupid, but sometimes the answer is
you need to run everything you read online through your own personal BS meter to determine if it makes sense to you.
