A guy I met this weekend said these were molds for car tires or wheels back in the 1920`s.....what do you think?

It seems pretty far fetched to me also.

Molds for car tires are metal not wood. Those are molds for making sand castings for machine parts.

Check out this Youtube Video... It is from the Brunswick Tire Company the Film is from the 1930s. The Subject of the Film is how Brunswick Tire "builds a Tire"... Check out the molds used at approx. the 7:00 mark... https://www.youtube.com/watch?v=YZISUfi-6IkAt approx. the 8:07 mark, in this video they start working on forming tires on bucks... (video has no sound) https://www.youtube.com/watch?v=OfzO6QCxc68

Those molds are kind of similar but they I believe metal, but it seems the process uses some of these features.

Yes, they are metal...
Thought I would share the videos for those who were not familiar with the Vulcanization process...
The pressures and temps would destroy wooden molds, within minutes....

I was trying to imagine it as a sand mold, but I cannot fathom what the mold would have made.

Having worked in recap shops I can honestly say wood would not do as curing molds for tires. The temperature and pressure such molds are under would lead to quick failure of wooden pieces like shown in the pictures above. On top of that wood is a poor conductor of heat which is necessary to vulcanize rubber.
What your molds made is always a question when old wood positives are found. But definitely not tires. If you search google for old wood sand cast molds you'll see the myriad of orphan designs out there that we may never know what they made.

Those are patterns for castings. They used to paint the core area red to note where the core was. There would be a corebox that went with each pattern that would basically be the same shape as the red area. Without the drawings or coreboxes, it would be hard to tell what the areas where the black and red paint meet would look like.

The two large ones are flywheel molds like what would be on a hit and miss engine. The small one looks like a pipe flange for a steam pipe.
