24*3.14 = 75.36
16*3.14 = 50.24

smaller tire has a smaller rotating foot print. its gonna take it more turns at a given speed as the bigger tire. just like a runner with short legs vs a runner with long legs, its gonna take the guy with short legs more steps to run the same distance. highschool dropout physics.
