Well, honestly, it becomes a more useful road bike. Thinking about it, there may not be discrete categories, rather there's a spectrum. 32mm tires push a bike further away from a pure road bike and towards the touring side. Same thing with longer chainstays, higher handlebars and racks. Fenders too.
