What I know:
4.75" pattern
9" or 9.5"
positive offset; I'm pretty sure they are an aftermarket wheel for earlier C4 Vette fitment so they're not an ET0.

Does anyone know the maker or what they are called? Just wondering if others are out there.

 

Looks like a rear T/A or GTA wheel, except the center cap area, unless I'm missing something?

 

Well it's not 8" and I've seen the back before and it's not widened.

So I owe a backside picture.

 

The tire on the rim in the picture is 245/50R16, and it doesn't look like a stretched fit, so the rim is, most likely, 8" wide.

 

It's about 10.75" total width, so it's 9.5" like I remembered.

I can't make out anything on the back regarding width or offset.

The front has JWL. The center is different from an 86-87 or 88-92 16x8 `Bird crosslace wheel.

Just wondered if it was a known aftermarket design.

 

Kinda looks like some late 80s grand am wheels

 

The 15" wheelcover version? I can see what you mean.

Look what I found....

Here's a pic of the backside of a GNX wheel, saved from a Turbo Buick website forum. The GNX wheel is 8x16 with -15mm front/-23mm rear offsets, and it has the "dimples." The wheel in your pic does not have dimples.



Based upon the backside of the wheel in your pic, the MAXLOAD1580LBS is clean enough to read, and the JJX16 is almost clean enough to make out, but you'll need to wipe off the other parts of the inscriptions better because those are the rest of the sizes you're looking for: the number in front of JJX16(circled in yellow in the pic below, is the wheel's width), and the number after the word OFFSET(circled in red in the pic below, is the wheel's offset). Wet a rag and wipe them off.



It would be quite a stretch for a 245/50R16, which fits 7"-8.5" rims, to be mounted on a 9.5" rim, but whatever that number in front of JJX16 is, it's the width you're looking for.

Whatever the wheel is from, it's apparently not from a Buick Grand National/GNX, and it doesn't appear to be a GTA wheel either.

 

Yeah, it seems the center section paint keeps the numbers from being legible.

You'll just have to trust me on the size.
I measured them bead-to-bead about 10 years ago when they were bare. And externally last week.
There are a half dozen other 8" width wheels around here with the same size tire and the sidewall difference is noticeable.
They're 9.5" width.

 

Thanks Brutal.

 

Always glad to contribute when I can.

I pulled this from that site as well. Might help in your search

"If it doesn't say front or rear than it's not a GTA wheel. Probably an ARE (American Racing) wheel. Where the lug nuts mount, is it inset or flat with the spokes? If flat with the spokes it's an ARE wheel. Riken made a similar wheel that I believe had wider webs, but I am not sure about the lug nut mounting surface. The ARE's also used a smaller center cap."

Possible brands (BBS or Riken or ARE or Enkei)

 

Looks like they are probably Riken based off my "riken gta wheel" google search.

I attached 3 pictures of examples on a Fiero and a foxbody.

I love how the lil 5oh is trying so hard to be a T/A with the wheels and custom fender vents!

 

Brutal, you had it all figured out.

They are verified as Riken.

 

Awesome! Glad to help.
