And there is other data to support that RR is relatively the same until you hit about 60 mph, then it increases dramatically - which is probably where the video you looked at was coming from. |
I'm curious of the physics involved in this. On the surface, you would think tire resistance would be linear. What is causing the curve, is some sort of internal dynamics on the tire causing the change? Is is something like heat, or a harmonic vibration or something? Do speed ratings have any effect on when that curve occurs?
