I made some new smooth wheel covers, because two of the pizza pan ones have come flying off... So, I bought some more cheap plastic aftermarket covers (from K-Mart) - a set of 4 is about $22, but I now use two of the spring wires per cover, so you only can use two.
I then stretched cloth over the front, and painted on glue, and then sprayed them black. This one is very similar to what I did:

The only difference is I used waterproof wood glue, which doesn't smell and cleans up with water (before it dries).
