Doors, and it probably isn’t close.

But people have wheels on some of their chairs, on the bottom of some of their footwear, bicycles, big giant trucks, even planes have wheels. I would imagine there to be slightly more wheels in the world than doors.

But then there are doors on those things with wheels, plus all the doors on buildings, closets, cabinets, etc.

Definitely wheels. When you factor in toys it's not even close

All those toy cars also have doors, and probably 4 doors.

Mercator @ 13/3/2022 14:38 Most people are third world, and I have a feeling they have more doors. Americans are extremely wasteful. Have you ever seen a used door store? There a tons of used tire shops. I bet there are more used tires sitting junk yard and pick a part locations in the US as doors in the world.

Tires aren't wheels. Tires go on wheels. The fact that there are tires sitting around all over the place would seem to imply there actually aren't that many wheels out there.
