I believe the military did some testing on 3D printing wheels for some of their vehicles. I could not find the specific article where it mentioned this but I believe they looked like the picture below.

There is currently a lot of work being done on 3D printing the rims of a tire but applying 3D printing technology to the actual tire is a difficult process. I do not think the tire would need to be completely plastic because of the current advancement in 3D printing materials but a mixture of plastic and something like Ninjaflex could work.

Hope the information helped and great question by the way.
