For my Corollas I have two different types of 13 OEM wheels.

One kind looks like the bottom two photos on:

The other kind resembles this except the holes around the rim aren't as large. This kind takes a solid circular center cap that does a good job of keeping the lugs clean. Is there a center cap or wheel cover for the type shown on that page that will do this job? The circular ones that I have do not fit that kind of wheel. The area around the hub isn't designed to accept them. There are fancy looking plastic wheel covers in the auto stores that cover the entire face of this kind of wheel. But when you go to change a tire on a vehicle that has these, you find the lugs are grimy and rusty.
