A careful reading will reveal that the parent poster merely said they spent 4 years doing PhD research, and during that time, also indirectly looked at things somewhat related to tire research. I don't know how much time you've spent in academia, but when I wrote my thesis, there were a couple "indirect" things like that that I could sound knowledgeable on but really knew no more about than someone could learn in an hour of internet reading if they really tried. A source is what it would take to convince me, not an internet commenter claiming to have googled something during their school years.
