Why are bike tires so narrow and large diameter compared to car tires? What tradeoffs are here exactly? Motorcycle and some ebike tires are more similar to car tires than to bike tires, so i guess it has something to do with braking length at maximum expected speed, and probably also with weight of vehicle, as to not exceed some specified pressure on road. There has to be so many more reasons (weight? air resistance? some other things affecting efficiency or safety? ???)
update: apparently friction involving things that are bendy is monstrously complicated subject, and also there are material limits like maximum allowed shear stress
I think it only holds if it’s a magic engine that always hits the same max RPM regardless of load, and the transmission is the same.
Otherwise the top land speed record would be held by a monster truck.
yeah this sounds like “all else equal” case but all else is very much not equal
