Where's the square wheel? Didn't it come prior? And after the square wheel came the triangular wheel, which eliminated one bump.

It is not the bumb count, it is how big they are. In your aproach next update would be "rotating ski", while right aproach is make more bumbs, but smaller ones. Honestly it doesn't need a genius to invent a wheel, just sit on top of a round log in campfire and you invent one by accident.

With that picture it is actually hard to say which one of those are improvements. Modern car tyre acts more like a stone wheel than spoke wheels which are distributing forces to sphere and push/pull to spokes depending the construction.
