Yes, you're silly enough to believe this. No, you don't have a good reason for your belief. If you want to understand how foolish you are I'd suggest the MIT Press book "Bicycling Science" - a standard read for any designing a bicycle. As you're probably too lazy to read it, you might skim the dummies version at

what does being 6'6" have to do with tire size?
Because people who are taller tend to weigh more, Braniac. And the tyre width you need for a given surface depends on weight.
why aren't we focused on his weight. I'm 235lbs with 35c tires light knobby tires on my bike, it easily handles dirt trails. He didn't say he want's to do full on cyclocross, just that he may take the occasional ride on a bridal path.
It's
bridle path. And a standard cross tyre - intended for a 160lb ish rider - is 35mm. So for a reasonable weight for a 6-6er, 35mm is about right right for a
bridle path. 40mm would actually be better - wider tyres are banned from cross racing because they are an unfair advantage and would "de-skill" handling.
