Hi guys,

I have a problem identifying a set of rims that I have.

The size and brand are 18X8 Starcorp rims.

I had them on my HQ using spaces to make them fit. I was told that they were Commodore rims.

So I put a set of GTS rims on my HQ and decided to put the Starcorp rims on my VE SV6.

I found that the stud patten was different.

The stud on the rim seems to be slightly narrower then the stud on the Commodore.

Would this mean more likely they are made to fit a Ford?

Your help would be much appreciated.

These are all 5 stud patterns.
Commodore PCD is 120 mm. 114 between centres across. 70.5 from stud to stud. Studs are M12.
HQ-WB PCD is 4.75" (120.65 mm). 115 between centres across. 71 from stud to stud.
Early Holden/Torana PCD is 4.25" (108 mm). 103 between centres across. 63.5 from stud to stud.
Ford PCD is 4.5" (114 mm). 109 between centres across. 67 from stud to stud.
Valiant are different again.

Thanks James.

I reckon by what you have said I have Ford rims.

I am going to make a call to the wheel shop and hopefully they can help me too.

Lucky I didn't sell them to a Commodore fanatic!

JBM, that is mostly correct but there are many others. i.e 4 cylinder VB Commodore had the same stud pattern as FE - HG Holden which is very very close to Volvo, Most Fords since the mid 1960s are the same and the same as toyota, later Chrysler including later Valiants. HQ is the Chev pattern which is very close I think to Mercedes Benz also. But that is just the stud patterns, there are many other considerations when matching up wheels. See if you can chase up the manufacturer and they may be able to tell you how to identify them.....Jack

I responded with the info I had regarding HQ and Commodore stud patterns as mentioned in the OP. I do understand that track widths, offsets and rim diameter also need to be considered when choosing an appropriate rim and tyre package for a particular vehicle.

The 4 cylinder Commodore pattern you mentioned if same as early Holden/Torana was covered.

Hi James. I've only added to what you said put in a different light. not to negate your help to to HQ Sandman. You can come across some strange stud patterns though. I had a large trailer that was made out of a caravan chassis that had a strange stud pattern and after own it for 10 or more years I got a flat tyre and none of the tyres I had around the place, holden, ford etc would they fit and I think in the end it turned out to be an early ford and it wasn't easy to find one......Jack

How can these wheels be a ford pattern if they were on a HQ. Come on guys think. You say you needed to space them to fit a H series so the pattern is either HQ or Commodore CAN'T be Ford. The spacer makes it likely they are Commodore. You then say they won't fit a VE. NO EARLIER MODEL COMMODORE WHEEL WILL. The VE uses 14mm wheel studs whereas VZ and earlier are 12mm. This is the tightness you are talking about.

Doesn't make sense to me. The spacers are made to fit my HQ stud pattern to link up the rim. Therefore it doesn't necessarly mean it is VZ rim or Ford rim etc. In saying that, I wasn't aware of the different size stud patterns in the VZ and the VE. I will try to find an earlier Commodore to see if it fits. Thanks EH.

Fair enough about the wheel adaptor. When I read SPACER I assume it was just a spacer not a stud pattern adaptor. Two different animals. If the adaptors are commercially made they will have both stud patterns marked on them.
