Total threaddrift, but can you give more insight into your calculations?
0.0015 m^2 at 36kmph by my calcuations = 1watt. @ 45kmph it's 2 watts.
I find it hard to believe today's Tour de France pros would be using 28's vs the old school 22's if it was costing them 30ish watts. That's about what some riders would hope to gain with oxygen vector doping.
