Attached photo is of inside rim of what appears to be an original style front wheel on a 1990 ZR1. Anybody know anything about decoding this?
Have not yet removed wheel to look for other markings.
Thanks in advance for your input.
The front wheel on a 90 size 9.5 is the same as any standard 90 wheel not specific to the ZR-1.
Thanks We Gone:
I was aware they are the same. Would these markings indicate an original wheel?
I intend to remove them for cleaning and was wondering if these markings would be on an original wheel and if there would be more markings to look for.
I'm not sure of the markings in your pic. I do know that you should find cast in markings on the inside of the wheel. Hopefully someone will post in that knows more about 90 wheel markings.
My '90 wheels have that information also and I believe that likely the 90 is year manufacture and 3-7 is date. My #653 has 89 10-31 and the other side 89 11-15.
When you remove they will have a casting as LEFT - RIGHT and also a 3 letter code I believe.

<br />Thanks WVZR-1:<br />This car is #442. If I remember correctly the build date is 10/89. Will double check that. I intend to get the wheels off sometime soon & clean/check everything.<br />The reason I am so curious about the wheels is that the centers around the lug nuts are painted black. Doesn't look like someone just decided to paint them. Edges of paint are very uniform and the paint finish looks nearly "baked" on. The "spokes" are also black on the sides.<br />Here's a pic.
GM never painted the 90 wheels with the black paint in your picture.
Stock 90 wheel

I am curious to see what markings I find when I remove them. I was aware that GM didn't paint any like these.
Did anyone make aftermarket wheels that would look the same as the OEM?
I'm not aware of any aftermarket wheel like the 90. It would appear that WVZR-1 best answered your question of them being stock in fact I learned something new also as I had never seen these markings.

I believe that if most with '90 cars actually look "a little harder" they'll find that information.
'90 wheels are generally sold by the casting information on the back-side. Mine are 10119547 and 10119548 on the 9 1/2". I didn't look at the 11"
***The information on the rim flange maybe is only on production wheels and wheels done after production for GM SPO might be missing the rim flange information.

I just acquired this car about a week ago and have been going through everything to see for sure what I have. (I did do a pre-purchase inspection of all the major things) The wheels have had my interest since the first time I saw the car. There is absolutely nothing else about the car that deviates from original that I have found yet. Even the date codes on the glass check out.
If the wheels have the correct stampings I guess we can say they are "exclusive, 1 of a kind COPO special order". Or maybe better yet, "Have no clue, guess somebody painted them".?
Thanks to all you guys for the feedback. Sure I will be back for more.

if your car is #442 and 10/89 production I'd say it's very obvious that the wheels are NOT original, NOT a COPO of any sort NOT a ONE OFF or exclusive. Painted - YES!!!
The wheel in your snapshot is several months newer than your car!

Darn!!!
Guess I better throw the whole thing away and look for another one!! OR: Maybe they had to set the car aside after being built and wait on the special order wheels ??
I will update after I pull them all off and check markings on all the wheels.
I have reached out to the original owner to attempt to get more history on the car. Maybe I will get some feedback soon.
THANK Guys.

'90 Wheel Question
