Hi Andrew
I wonder if rolling resistance is directly related to friction (in the bearings)? If so the resistance will be directly proportional to weight of car. It always confuses me when I’m told friction is a function of perpendicular force not area of friction material. Theoretically 1” brake shoes should perform the same as 1 1/4” shoes. But that doesn’t seem to be the case in practice.
Cheers
Howard
