I got a 19x9 squared setup of G37s coupe wheels from eBay for my 2009 G37x sedan, but only one of the four wheels actually fit onto the hub when I went to get them installed at a tire shop. The other three wheels’ center bores were too small. The part numbers are the same on all 4 though (N062-990A) and I seem to be the only person with this issue. I have no idea what the next step should be. Do I have to get them bored out a machine shop? Is there another option?

I took 3 pictures of each wheel. The first 3 show the one that fits, and the next 9 are of the 3 that don’t fit.

 

I think you already have your answer, which is to find a shop that will expand the center bore.

"Wheels America"... pretty sure that's replica stuff, which is why they can be had new for around $300. I bet they're heavier than OEM too. But I don't really know, just a guess. Or maybe it's a reman of a set they didn't realize wasn't OEM. Either way, you're stuck.

Man, that must have been super disappointing. Good luck.

 

I was going to say, if they are reconditioned. Did they paint or powder coat the bores, that could cause an interference with them sliding onto the hub.
