Has anyone experienced cracks in the bead rin on their P/N 4578P wheels? I have not hit pot holes but have now two wheels with cracks on the the inner bead rims. These are not small cracks both are at least 2" long. Is there a recall on these wheels? I'm not a happy camper about this!

That seems like an odd part number for a GM item. They are typically 8 digits, no letters (I have seen some that are seven digits but not commonly). Are you sure these are GM rims? Do you have any pictures to post?

I have not heard of any problems wheels. Some pics would be great.

If your car has the 9 spoke polished 18s I have a good wheel I'll sell you if you need it.

$200 each on ebay. Dealer would want much more. http://www.ebay.com/itm/CADILLAC-CTS-STS-WHEEL-RIM-4578-4610-POLISHED-9596894-/280621796914?item=280621796914&vxp=mtr
