Weather Spotters wheel cover how to
Examine your existing wheels looking for mount points: File:Rim pre cover .jpg
Locate a good spot for drilling and taping bolt holes: (in my case it was the ridge in the middle of the rim): File:First hole.jpg
Drill and tap 3 holes spaced 120 degrees apart (measure with protractor). I made the holes in the pizza pans first then used that as a template for the rims. I messed up the first set of holes (they were in 1/2" to far):
Attach using galvanized bolts to that mach you tap (mine was 5/16 x18 and 1" long (.5 would have worked)):
take for a test drive. Mine was fine so I took them back off to paint the back side (black) and to clear coat the front. I chose to do this as rust insurance, steel pizza pans = rust after a few rocks hit them.
During my testing yesterday the pizza pans made a racket, I though they might be coming off, nope still on tight. It took me a few min to figure out what was causing the noise. If I push in on the center of the pans they flex in about 1/8" this makes the edges lift off the outer edge of the rim. when they come back they make a popping sound (try this at home, take a pan hold the edges and push in at the middle, release and that is that I have).
to fix this I was thinking of some felt pads on the inside of the pan, but they would not handle the wet weather very well. After some wondering around the workshop I got an inspired idea. I took some plastic tubing, slit it down one side and put it over the outer edge of the pizza pan (see thread for pics).
I used some hot glue at the joint. Once on the car the bolts hold it tight to the rim!
After a test drive that pizza pan stopped making noise (I can hear the others still). Now I need to make a run to the hardware store for some more tubing (4.5" per pizza pan).
