Aftermarket Rallye Wheel nut taper and center hole

Hi All,

Not sure if I have a issue or not.

On my 68 Have just swapped from original GM 15 x 7 Rallye wheels to Wheel Vintiques 15 x 8 rallye wheels, the wheels I have are their 30 series wheels that they list as to suit Corvette , they fit up fine, backspace good etc .

But two things the taper on the wheel stud hole is either just not quite as deep (which would be okay) or a different taper angle (which would be an issue) Anyone know if they run different tapers or is it just the depth.

Also the centre hole in the wheel is slightly larger than the original wheel, which is close to the axle protrusion.

Thanks for any help

Re: Aftermarket Rallye Wheel nut taper and center hole

HP I used the 15X 8 aftermarket rallys from NPD on my 68. I bought new acorn nuts for the lugs and they worked fine ie 7/16 X 20 thread I believe. My old 15X7 rallys lug holes were very worn and looked very different from the new virgin wheels lug holes. Also the aftermarket wheels hub opening is larger as these rims are lug-centric not hub-centric as your original 15X 7 rims are. You can buy hub spacer rings to better center your rim to your hub. The wheel MFG usually states lug-centric balancing required. good luck with your install.

Re: Aftermarket Rallye Wheel nut taper and center hole

Thanks Icpop, had another good look and taper is the same.

I guess the lug-centric vs hub-centric deal obvioulsy cant be any kind of safey issue as I notice most aftermarket wheels like Centrline etc always seem to be lug-centric also, yet OEM wheels are generally hub-centric.

What would be different from a wheel listed as a Corvette Rallye as opposed to a wheel listed as a Camaro Rallye, is it only size and back spacing etc

I think style may be a little different but for sure backspacing is less on a Corvette rally.

Re: Aftermarket Rallye Wheel nut taper and center hole

I have a concern regarding the hub size on aftermarket rallys. Here is a pic of my old steel wheel and pic of the new rally. Notice the rally center hole is larger. Is this alright? Any safety issues? I'll buy new lug nuts thats for sure.

Re: Aftermarket Rallye Wheel nut taper and center hole

The only real issue between hub centric (most OE) wheels and lug centric wheels is the possibilty of picking up an extra vibration (or four...) if the wheel is not perfectly located on the studs. If you mount the wheels on the car and notice a new vibration, you can pick up some rings that will fit over the hub and fill the gap between the hub and wheel to make them more hub centric.

I also have 15X7 and 15X8 corvette rally wheels that I got from coker. I needed to go with the corvette style to get the backspacing I wanted (I think the camaros are also lug centric). They supplied new lug nuts and came fully balanced with the tires. I made sure to snug up all the nuts in a star pattern and finally tighten them all the way down to make sure that they were centered. I have not had any vibration issues.
