My post in the WANTED section (sorry I put it in the wrong category !) for my wheels makes me wonder is it even worth trading. Every time I have searched for Rader's like these, I mostly find 14 inch wheels with all bolt patterns except the big 5 1/2 pattern. 15 inch ones seem to be harder to locate, so are these things rare ? I don't,I am just curious, I will still just trade even up. I would rather see them go on somebodies traditional car as I am not that fond on running adapter to use them on my car. They are as thin of adapter as I could find (5/8" thk.). I was under the impression there were 3 versions of them: 1st version had no ribs on the spokes and were possibly outlawed in the old days, 2nd version like the one I have, one rib down the center of the spokes and the 3rd version had the 2 additional ribs on the sides of the ribs plus the center one (weren't these the type used on the actual BATMOBILE ? ) Just thought I'd ask. If any place is going to know the answer, it will be here on The HAMB !
