rim size?

[hothead115]

hey guys just wondering what size the rims came out in a vc? 14 or 15 inch?

[VH_Commodore_Wagon]

i think it was 14" except SLE which has 15x7" Irmscher alloy wheels

[Outlaw Torn]

14's, pretty sure thats right though all the variations of the vc.

[walesy]

yeh 14's the vl was the last one to come out with 14's as standard im pretty sure VN's with 15's

[SL/ENUT]

i think it was 14" except SLE which has 15x7" Irmscher alloy wheels

Not quite right, yes all VC bar the SLE had 14X6 but the SL/E has SLE alloys 15X6 standard. The Irmscher rims are on the VC HDT Commodores

hay fat our burnout car is guna rock

yeh 14's the vl was the last one to come out with 14's as standard im pretty sure VN's with 15's

Nah, VN's came standard with 14's too, 15" on the Calais and SS.

[JD]

the vc's came out with
13's on the 4cyl models and they had the torrie stud pattern
14's on models L and SL provided they at least had a six
15's on SLE and SS models.

hey sorry to ask a question in your thread but what size rim can i put on my vk? i have heard something about "2 inches bigger than stock wheel size" on here, is this true? and if so what would happen if i put 18" (the size i want) on my car?
cheers pat

[SL/ENUT]

Most likely a defect mate if you put 18s on your VK. The ruling is that your allowed to increase that "standard" wheel size to 2 inches bigger.

15's on SLE and SS models.

there was never ever a VC SS model, only the VC HDT, the proper name for them.

[EvoVIIIJDM]

my olds vc came out with those terrible 14 inch steelies. As soon as i bought it off them on went some 15" Polished VK Calais mags.

my bad i was thinking vh

[vl rb30e]

i have 18 inch cromes on my vl and never had a problem and my mate has 20 inch rims on his vc brock

I have NO idea who started that rumour... but it's perpetuated by forums and magazines and blokes in garages across the country.

No such rule exists!

Apparently the law that DOES exist is that the biggest you can go is what was offered on the car (as in, you can buy a VY with steelies and stick 18" rims on it, because the SS had them, and that's what that model of car has been engineered for.)

But I'm yet to see any evidence of EITHER laws.

Either way, I have 15's, I know I'm safe

edit: Oh let's not forget that 16's were available on VKs - 95% sure the HDT rims (forget their name... gr!) were available as a 16... so even going by the first law and second law 18s on a VK is legal

"(i) Vehicles manufactured on or after 1 January 1973 (ADR 24) are not permitted to increase or decrease the diameter of the wheel by more than 50 mm than the largest or smallest wheel listed on the tyre placard."

Technically this means you can only go 1 inch larger as 2 inches is more than 50mm, however they are lenient and let it pass at 2 inches.

However, ADR 24 ceased to be in use from January 1st 2005. ADR 24 was Tyre and Rim Choice. This is now covered by ADR 23 (Passenger Car Tyres) and ADR 42 (General Safety Requirements).

I have recently been in communication with an RTA engineer, aquiring the knowledge to pass a project that I have going on.

We only the other day spoke on this subject and I have to say that you are spot on dude. I'm pretty sure that you comments are straight from the book, word-for-word.

However, he told me of a little secret and its legal. Buy a VT tyre placard and replace the old item. Its a loop hole at the moment .lmao

Ok so legalities aside for a moment, what is the maximum rim diameter and width that will fit on a VH SLE without need to modify the cars body or suspension components?

I have seen two for sale with 18 and 19's (Holden wheels) on them. Are these just a straight bolt on proposition?

Thanks,

TEMPA

ok where do i get one and how much are they?

Well I havn't actually got that far (Still in production) - I'll find out and post it here, bearing in mind that that is current NSW law. Don't know about other states.

Hey Kain,

Thanks for your help.

You need to bear in mind one thing when changing wheel/tyre combinations, and that is a concept called "rolling diameter". That is that the overall rolling diameter of the tyre/wheel combo, must not change, or if it does it should only change "plus one". Bear in mind a 185/75r14 has the same rolling diameter as a 215/65/14, but looks fatter on the car, and handles better, plus one fitment would be 205/65/15 or 215/60/15.

It is important that rolling diameter from the original equipment is not modified, as it will affect speedo readouts, mileage, front end geometry, and others, most importantly it can and WILL void most insurance policies if the modification is outside the ADR specs for that model vehicle.

I have seen many early model commodores with HQ-WB wheels fitted, sure the stud pattern is the same but the "RIM OFFSET" or PCD is completely wrong and not only looks stupid, due to the fact that they stick out to far, but are DANGEROUS....due to the changes in steering geometry and the extra stresses on wheel bearings, brakes, etc..

On most early Commodores, 15 inch rims are the biggest legal size, unless yours is a brock/walkinshaw, bear in mind these models where set up with different front end/track specs to allow the wheel/tyre combos to be bigger.

You really cant just slap huge wheels on to ya grandfathers old VK and expect everything to be fine... take the time to talk to a professional tyre or wheel or front end specialist and get the facts... you may be surprised at what you should and shouldnt do......remembering that wheels and tyres are one of your most important SAFETY features of you car, they are your last contact with the road in regards to steering, braking, and control of the vehicle, looks may be important but you dont look too good when your prized possession is wrapped around a telephone pole, or worse... just because you wanted to look cool.
