[QUOTE="champion, post: 22309, member: 443"] I was told of a study which is in MPH, last month, (Or possibly the previous one.) It proposes the idea that as speed increases aerodynamic drag increases at a greater rate. and that as speed increases, rolling restistance increases by an even greater rate... Thereby making tyre choice more important for top speed than aerodynamics: Problem is the artical says that aero drag increases by the power 3 and tyres to the power 4. But doesnt aero drag increase by 2? In which case is the part about tyres rolling resistance still true? Really I would love to try and get hold of a copy of this report. Only reason I ask is: I am currently doing my dissertation looking at motorcycle aerodynamics, and this would be a brilliant point to finish my conclusion on. Alex [/QUOTE]
