I'm with Tina, above. I'm also thinking that they would make great squirrel baffles for any hanging birdfeeders you might have, too! And maybe sundials...?
You could make birdbaths from them . My neice made me one out of an old washpan of my Mom's. She cut a small tree from the woods and drilled hole in pan. Used a rubber gasket or silicone to seal aroung after screwing it to the tree, Then add a base to make it stand. I don.t know why the hub cap wouldn't work. Could use landscaping timbers also.
Depending on the type of hubcaps, you could bury part of them with them standing up and arrange them around a flower bed, as a border of a sidewalk, or if they are deep enough you could use them for birdseed and hang in trees, you may have to drill some holes in them to do this, but the old Ford (I think) pickup hubcaps were deep enough for a bird bath, just keep it clean and low enough to check the water level regularly.
If you are a welder or whatever it would take, you could make all sorts of things. Just let your imagination soar!
