The fortune teller's wagon in the Sims 3 is my favorite lot. I added a livable wagon to it and made it into maker's market/wagon circle to make it more of a traveller's community. Best lot in my save file; wagons are super fun to build. Love what you did.
If you have horse ranch there’s the upright wheels in the debug menu(which can be accessed on console) but if you don’t have the pack I don’t think there’s any other wheels. But I have seen people using pet her objects for wheels like round windows
