Title: Wheel sizes
Post by: phil_long on January 15 2013, 10:56:13 AM

I know its a 5x4.75, but what is that in mm?  5x120mm?  Thanks

Mathematically it's 120.65. I have a feeling that .325mm radius difference is within SWAG.

I've seen posts where they say that the load on the studs using a 120mm vs. 120.65mm bolt circle is pretty high.

I'd recommend using "wobble nuts" if going to run with a BMW style bolt circle.  Let me know if you need a link.

Thanks Mike! 120.5 is bit better than 120 though, right?  :)

In that case the studs will be .003" tight on the radius.



If you're not well versed in 'thousandths', the hair on your arms is .002"

Idk. Lol. A guy has them on his GN on the other board.  I sent him a message a week ago and he still hasn't responded to me.  I was basically asking him how they fit, etc, etc.
