Decorated bus tires
While riding in my brother-on-law’s car the other day, I caught sight of this bus tire that had the nuts all covered up. Now I know some drivers do that because they want to keep water and moisture from out of the nuts. The reason they do so is that it will not be so difficult to unscrew the nut when there is no rust on the screw. I think this is what those were…the protective covers…but protective covers with a difference. Not bad…it made me take a second look!
