Wheel warning for Commodore
The Drive Team, The Sydney Morning Herald, 15/12/06

Holden has told its dealers that the new VE model's wheels won't fit old Commodores.

Holden VE Commodore: production line at the Elizabeth factory in Adelaide.
When Holden introduced the all-new VE Commodore in August it changed some crucial dimensions of the wheel-locating system. This was done to avoid confusion on the production line (as the Holden factory will be building both new and old models for some time yet) and to cope with the new Commodore's extra weight, width and grip levels.

Holden sent the following statement to Drive on Wednesday: "Fitting VE wheels onto a VZ [or earlier model Commodore] is not recommended or condoned by GM Holden as it raises some safety concerns as there are two major differences in the wheels."

Holden said the VE Commodore has 14mm wheel studs and earlier Commodores have 12mm wheel studs.

"If a VE wheel were fitted onto a VZ [or earlier model Commodore] there is a concern that there would not be enough bearing area under the retention nut on the aluminium wheel, which, worse case scenario, means the wheel could potentially fall off."

Here's an opportunity for some one to make some money and start making some 12mm wheel nut with a large shoulder........ :spoton:

I wonder if you replaced the 12mm studs with the 14's...would this work???? You would have to redrill everything..... :fool:

Fittitng 14 mm studs to a VB - VZ Commodore should be a straight forward job. A bit of drilling so the larger stud would fit the early model cars would be required. The only other issue would be, has the offset changed?

Using a 12x1.5 nut with a larger taper for the purposes of using a VE wheel on an earlier model Commodore is not advised, as there would be too much clearance betweeen the wheel stud and the drilling in the rim. You would wind up with an extra millimetre clearance all around the stud. And as Joe Frost would say:

"That behaviour is un-asseptable."

In theory it should work, provided the rim is correctly centre bore located on the hub. The problem would be to find a nut maker who would put his arse and company on the line to cater for the ( possibly ) few who would need such a nut.

If Holden were smart they would make sure the wheels on the VE don't go anywhere near the earlier models stud pattern wise.

I am 99% sure that they have a different stud pattern anyway

If they had a different stud pattern, then why would GMH only make mention of the different stud size? If the stud pattern was different, surely they would mention it. Unless it's close enough to force on ( eg: HQ and Crappydoor ).
