I think it only holds if it’s a magic engine that always his 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.
Comment on Why do tires have the width and diameter they do?
rain_enjoyer@sopuli.xyz 1 day agoThe larger the tyre (diameter), the higher the top speed achievable practically
this only holds when it’s using the same transmission?
as of width, here i think tradeoff is that with wider tire you can use lower pressure, and if it’s wide enough, also lower diameter. with lower pressure i think there might be less wear (?) but also bigger width means there’s more rubber to flex and that means energy losses by this mechanism. this is why it makes sense to use wider tires where all the power is not supplied by user

yeah this sounds like “all else equal” case but all else is very much not equal

A larger wheel allows a smoother ride as a smaller wheel and thus allows for higher speeds on uneven ground.
