I know that centering rings are suppose to help center the wheel to the hub and I believe take up the gap if any between the wheel and hub and you have to use aftermaket lugnuts I believe cone type but does anyone know the correct length or do different wheels have different length's I presently have mcguard spline drive 12m x 1.5 I do not have centering rings.

When i got these wheels I was told the tires were out of round so I recently just purchased new tires but the vibration is still there it's not just a little but alot so I'm thinking maybe the lugnuts might be the problem had the wheels checked out at 2 different places to check for bends both places said 2 were perfect and 2 were bent but it was so miniumal that I would never feel it so if there are any wheel guru's at there any in-put would be appreciated oh by the way with the stock wheels and lugnut's the car drives just fine.
