I am always needing to put tires on some items that I use such as large
fans, homemade generator/s, carts, etc. I have used drill-rod once in an
emergency. Other times, all-threaded rod but I know there is other
material
that has to be cheaper.

What am I overlooking that is dirt-cheap, like me?

I've used a pair of grade 8 bolts (heads cut off) welded into each end of an
angle iron. Then bolt on selected wheels. Weld or bolt into place.
