Tires make biggest difference in MPG below 50 mph; aerodynamics is the most important factor over 50 mph.

It makes it sound like aero shouldn't be considered at all below 50...
According to that chart - aero costs ~140hp @50mph, a tad below 100hp @40mph, ~50hp at 30mph....
Seriously, 50hp is half of my engine's output... And that said - according to that chart - aero beats tires around 20mph.. what gives? I may be reading that chart wrong (whenever I use a chart like that - the x axis is zero for everything)...
