I think Jobst nailed it on the head. While it might be interesting to
explore all the nuances of this phenomenon, all that really matters is
what the tire does when actually rolling down a steep hill with a
rider on board.
But to add my voice to the chorus of armchair testers, I'd suggest
that it might be interesting to see the effects of using a deep rim on
the rear wheel to see how effective the extra mass is at getting rid
of the heat.
