Are you thinking of wobble nuts?

Try putting a G8, Camaro or PPV wheel on a Corvette--it will not fit....what makes anyone think it's "OK" to put Corvette wheels on any of these cars simply because they can put the wheel over the studs?
Yes, there are a lot of people doing it and getting away with it, I will not deny--from an engineering standpoint it is wrong and if no one will speak out about it, I am compelled to do so.
You have not answered my question--are you using hub centering rings?

I have heard this, too. The common argument is that they are all 4.750" (which is exactly the same as 120.65mm) and if a wheel or car is said to have a 120mm bolt pattern, the manufacturer is just stating the size as 120mm instead of 120.65mm. I don't think this has ever been proven. I never really cared or thought of a way to actually put this to the test... until now. I drilled two bolt patterns in a piece of 0.250" thick aluminum on my mill which does bolt circles. I made one pattern 5x4.750" and the other one 5x120mm. My studs measured 0.545", so bored all the holes to exactly 0.546" with a boring bar. The initial hole was made with a 0.500" end mill, so there was no chance of a twist drill walking. The bolt circles are perfect. Well... the 120mm bolt pattern fit over my studs perfectly and tightly. The 4.750" bolt pattern only fit over the portion of the studs that is not threaded and a smaller diameter than the threaded portion. It was clear that each stud was not centered in the 4.750" pattern's holes. You can sort of make this out in the photo. That being said, I still have yet to hear of a failure by using 5x4.750 wheels on a 120mm car. The difference is pretty small (about 0.013" per stud).Maxspeed96ct wrote: Some call it 5x120, 5x120.65 or 5x4.75, depends on the manufacture. Its the same

Nice demo - the pattern measures out to 4.75 vs 4.72, admittedly not very much, but clearly different enough to indicate that a wheel for one pattern does not center up as intended on the other pattern.kevink wrote:I have heard this, too.

I am glad you searched the google interwebs and are now a wheel engineering expert, but I dont care about your opinion. stick with your steel PPV wheels if you'd like, I dont care what you do.
But please dont bash myself or others on their wheel choices. These are perfectly safe to run and its the same pattern.
And Please stop sharing information on the internet you really know nothing about.
CTS-V guys are trapping 135 mph + on vette drag packs, with many 60' times in the 1.5 range.
Some call it 5x120, 5x120.65 or 5x4.75, depends on the manufacture. Its the same
I've done it on my previous G8, and many G8 owners do it too.
There's even BMW guys using vette drag wheels.
BTW, the reason G8, camaro, ppv wheels dont fit corvettes is because the corvettes have a larger hub bore. Youd have to machine the hub of the wheel.
It has nothing to do with the lug pattern.
seeing your a interweb wheel expect, i would of though youd know this.
