Wheel Identity please help!
Hey all, new here. Any idea what these go to? I got these at a flea market and I thought they might be for an 88 Fiero GT but those are flat and these curve in. They're not the GNX/GTA wheels either, those are flat also. I looked all over the internet/ebay and cannot find them anywhere! Thanks in advance!

Re: Wheel Identity please help!

Re: Wheel Identity please help!
I've fooled around W-bodies for a while (I have a '95 Cutlass Supreme convertible)...and those look like wheels from either a Pontiac Bonneville, or a Grand Prix.
Re: Wheel Identity please help!
I'm not sure what bolt pattern they are, how do you find that out? I think they're 16x8. The victoria link rims are flat but yes they look the same. What year Bonneville or Grand Prix?

Could be from late '80's to mid '90's. IIRC, they were made by Kelsey-Hays. Look on the back, and see if there is a KH cast into the back side of the wheel. If so, that's probably what it is.

30L413S is what I see
10958
1M421D is what I see
10935
28L424S is what I see
30L411D ??? 30L444D ???
??311D ???
15x7
Some are hard to distinguish but they are 15x7's and not 16x8's like I thought. I didn't see any other significant stamping like a company logo or anything.

Re: Wheel Identity please help!
Probably front drive w body rims. Measure from the center of one hole to the center of one across from it. Rear drive GM cars are 5 bolt by 4 3/4 in. If I recall front drive are 5x4.5in.

I looked on this site also but didn't see a 15x7 dished aluminum black center wheel

Re: Wheel Identity please help!
Yeah those do look exactly like it, but like you said not black. So 85-87 firebird maybe? I had tried calling those people from that website and gave them the numbers on the backs and they couldn't pull anything up!

Re: Wheel Identity please help!
I have a set like post#12, except I painted the centers black. I use them with winter tires (in the winter). I have my 16x8's for the summer... not too much difference in looks to boot!
Just after purchase!<br/>$700.00 at auction.
