Hey, impressive results!
I just fear that mechanical issues are eating your savings!
I have been here a while and people have tried various ways to attach wheel covers. Several members have simply zip-tied the covers to the wheels, which never lasted long.
Vekke made some plastic caps that I tried, but they were too fragile, and so were the zip ties.
They sell various types of zip ties, so maybe some are UV-resistant, which may not matter if your covers have sharp edges.
I liked this idea, which dates back to the days of Kmart:

I think that I did buy some lug nuts to try it, but they were surprisingly expensive at a parts store.
Someone suggested grabbing them from a junkyard, but the other problem is drilling into a lugnut.
I am sure that it would have worked much better had I started with a punch, but I didn't think of it, and it didn't go well.
Members with cars with steel wheels, used resin and old t-shirts to make smooth wheel covers. Supposedly this site will ship 4 Prius covers for $70:

Metro glued pieces of plastic to his wheels to fill in the gaps, but they fell out.
You have done more ecomodding than I have and I have been here longer than most!
