Because people who are taller tend to weigh more, Braniac. And the tyre width you need for a given surface depends on weight.



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.
