What is the "real" bolt pattern?

Um, strangely I want to see the end of this

Here it is...

The bolt pattern is 5x4.75 there's plenty of wheels for this pattern. And I would personally use exactly what it calls for.But that's just me

I agree. I have GM S10 16x8 rims on the wagon with 255/50-16s. This is the right look for the car, sidewall height and width. This size tire was used on the Disco Corvettes. Getting really hard to find these days. What I really was after in my late-model Camaro wheel project was a set of the 18" steelies, so I could paint them similar to the 14" Malibu rally rims with the pentagonal gold-on-red caps. That's what was on my first wagon. Nobody is ever going to reproduce that wheel in 17", 18" or 19". That's the reason behind the wheel adapters.

If I was going to go fast or autocross, I would prefer purpose-built wheels. And I'd have to drop about $2K on the wheels and tires, though.

My $.02.

Back to the original topic...what's the real bolt pattern...

That's funny, that's exactly what I was planning to do before I found the ones I have for dirt cheap
 
It's equal to .013" side load on each lug. Not sure what mfg tolerance is but I'm going to guess -+.003 on each part based on normal milling tolerances, roughly twice the my half arse guess at tolerance stack.

Basically it's not right or "smart" but I've and dozens of others have run 5x120 wheels on 5x4.75 hubs and I've never seen ac failure.

Have I done it? Yes. Would I do it again? Yes. Would I recommend it, if I had to warranty it no. If I was telling a random online person with no liability to myself? Yes.
 
I have always been a fan of buying the correct wheels with the right B.S. or offset to fit but I get that it also limits your selection and can easily exceed someones budget trying to do that but IMO I would rather see someone use a well made billet adapter that actually has the correct 120.65 bolt pattern for our cars along with the correct bolt pattern for the wheel used rather than "guessing" what the tolerance is to bend a stud to make it fit an improper bolt pattern especially on a lugcentric application.
For me whatever you are bolting on you should be able to bottom out the lug nuts with no effort so you know when you torque it that it will be right.
Why create a possible safety issue regardless of what the percentage of possible failures are. This is just my opinion others may vary.
