Probably not, because I tend to be skeptical of rules.
However, I can't argue the rule per se because I don't have a wind tunnel. But, it's much more complicated than a simple rule would imply.
The rule is based on moving through still air, so may well apply to the front wheel when riding solo. The air in a Pelton, or over the rear wheel is much more turbulent, so aerodynamics are very different.
In any case, all decisions depend on the totality of factors. Wind becomes more important at higher speeds, and I doubt that someone shopping 36mm tires is riding at 20+ mph that much of the time. So, given the big picture, I'm more focused on traction and handling.
