Thanks, interesting reading. To me though, that "tast 4 results" graph showing 235 section tires with six pounds more rolling resistance force than the 175 section tires is quite a difference. The effect of tire width on resistance is fairly easy to demonstrate.
Dump the clutch in a car on narrow tires and then try the same car with fatter tires and it's fairly clear which one has the more resistance (/friction). Fatter tires would make for more rolling resistance
and aero drag I would think, by all normal rules of physics. Obviously compound matters too, but like-for-like the narrower tires would have less rolling resistance.
