[gooley]

Cost$

[walesy]

diddnt the hsv vp's come out with 18's? so 20's should be fine, its 2in above the biggest rim to come out on that model... my mate had 20's on his vl and never got hasseled and that was way over legal

[JD]

prob cost u about 1-2 grand for the cert but i would'nt know where there is one but u could try asking transport sa, ive heard they have a list of approved engieers to use for regency.

[gooley]

yeah but i dont have a hsv vp just a vp exec cheers JD i look it up

[walesy]

Argh... thats twice today someone has said this. If you dont know, dont say, because this is a big investment for someone and spending all that money because someone gave them INCORRECT advice is not fair.

It is 2 inches larger than what is indicated on your ORIGINAL TYRE PLACARD...So 2" bigger than YOUR car, not the clubsport model or whatever you want it to be.

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.

Note that this is only for vehicles made up to January 1st 2005 (when ADR 24 was made redundant... now covered by ADR 23 passenger car tyres and ADR 42 general safety requirements).

And to answer the question, generally $400-$500 is about right for an engineers report however 20" or larger will require some modification to get engineered, including brakes. You also have to have sufficient clearance to the wheels too. So it will be well over a grand.

You need to see an engineer approved by Transport SA so give them a call.

I thought so. I was also told that it's illegal to change your tyre placard in an attempt to make it appear legal (ie: put a new monaro's placard on a VN/VP).

So that means I should be fine with the VT-SS 17" rims I'm going to get
as my placard is for 15"s.

On that note, anyone got any VT-SS rims they want to offload?

[1991_Vn2nV]

Yeah its highly illegal to change any placard, including the tyre placard. 1 inch larger and cops wouldnt be able to tell, but 17's stock on a VN Exec or 19's like the ones bein sold on ebay... Most police are not that stupid. I repeat, most

[walesy]

oh ok sorry thats what i had been told before by tyre shops even though i told them i wasnt going to buy them, so i believed it to be true

[JSTPOZN]

vn2nv hit the nail on the head perfectly...

500-700 for certificate. depends how good most of you suspension is now.

but then your car will be sitting high... really high.. which needs another certificate to lower it which voids the first certificate.

get 20s. get stock suspension spare and just goto regency if you get done but make sure your car is perfectly safe no bent rails and shit

[tysons_2001]

i got my VR exec roadworthy with 18s, stock is 15s, so i'm guessing its 2" bigger than whatever come out on any model of that car, not just exec.

Good ol' VIC is good for something it seems, as long as the overall rolling diameter doesnt change by more then 5mm (from memory) you are fine. Basically as long as you go down in profile as you go up in rim size you are fine.

So you having 19's on your VN is illegal?

[coolvxss]

Do the police even realy care what size your rims are? A guy i know has 19s on his tinny bmw(those realy old small ones) and they look huge. and his been cruzing for a few years now without a problem. And couldn't you just put on stockies to get it through rego and stuff?

[roger05]

Cops just done my mate 4 19's on his VX Berlina, he is getting a placard from rare spares he knows its illegal but loves his rims. VN2VN sounds pretty right with his advice but to make sure you can ring regency and ask for web sites with the legislation on it and have a good read. Also you might need an aplication to modify before you go to crazy with stuff, for example every one's vn with vt brakes is illegal with out geting them inspected.

[JSTPOZN]

yes dylans rims are illegal..

my car (vn) is defected for 18s + tyre placard..

AirStrike

Its 15mm...but yeah... Bloody victorians NSW and QLD dont have the 2 inch rule anymore either... We're just a little slow on the uptake down here... Probably because because you guys piss in our drinking water...

So you having 19's on your VN is illegal?

Unfortunately yes.

[90VN55]

Its 15mm...but yeah... Bloody victorians NSW and QLD dont have the 2 inch rule anymore either

so we have the rolling diameter rule as well?

[1991_Vn2nV]

so we have the rolling diameter rule as well?

Yeah. There is a heap more regarding wheels and tyres, but in terms of overall diameter here is what is relevant in the QLD guidelines:

The rim diameter may be varied from the standard size but the overall diameter of the tyre must not vary by more than +15mm or -26mm.
These limits have been set for a number of reasons. Varying the overall diameter of tyres affects ground clearance, centre of gravity, brake effectiveness, steering geometry, performance and speedometer accuracy.
Generally, to meet these limits, 60 series tyres are fitted to rims with a diameter 26mm larger than standard and 50 series tyres are fitted to rims with a diameter 50mm larger than standard.

Track, speed and load rating, protruding tyres, tyre width etc. etc. is all covered too, but the above quote is all thats relevant to overall size.

By the way, I love the queensland guidelines because they have several examples of giving REASONS for the rules... Rather than just saying you can't do this like most states, they say why.

If your looking for a place in Adelaide, try tonkin engineering they allowed me to put 17s on my lancer which came with 13s

They charged me around the $250 mark and city discount tyres when they used to be up near TTP orgainised for them to come in and check it out. They took all different measurements which took about 30mins and they engeineer went home and did some simulations and the next day got a call saying yep 17's were fine and he sent a placard out.

Bit of a question though, i knew about the 2" larger thing so because I got my placard changed to 17s does that mean I could of put 19s on it? Doesn't matter now because of my commodore now but just curious

[phat_com]

LOL 19s on a lancer bahahaha
What happens if i "loose my glovebox and just so happen to find a brock glovebox with place card for 16" rims? can i put 18"s on my car?

Unfortunately you were ripped off. You are meant to receive all the paperwork, not just a tyre placard. That would not stop you being defected. You should receive paperwork regarding information such as your new legal eye heights etc. which all change when you are approved for larger wheels and authorised certificates from both the engineer and Transport SA.

You also had to go through Regency Park for an inspection following the engineers report, which im guessing you didnt. So they probably just took your $250 to stand around looking at your car for 30 minutes. If you wish to check, call the compliance number for Transport SA and ask them the process for having larger wheels engineered to your vehicle.

Well that depends on what a place card is.... But if you mean placard then no of course not. It is highly illegal to change your tyre placard, just like changing any of the plates on your vehicle (Vehicle Id plate etc.). Police will realise if it has a HSV symbol on the placard like those sold on Ebay and will defect you for it and/or fine you on top. Going 1 inch larger you could probably get away with, anything more and you are really pushing it. Especially on an old model commodore like the VH or VK.

[JSTPOZN]

haha

yes and they can defect you for it ....

bastards lol It was a vy i think on there so it could have 18's
