hey guys,
took my car over dickson this morning and was failed for too low. This is totally beyond me as I have measured my car many times and its far above legal specifications.
Currently it does however have after market springs and I am in desperate need of some standard ones for rego next week.
Anyone want to help out?
oh and if you have standard wheels let me know too ;)

they didnt say but it seems it may have been a part of the underbody. It wasnt the front bar or anything like that.
The wheels I put on for rego are 17inch wheels off a new toyota aurion but the rolling diameter is too large apparently. They have like 215 tyres on them so it makes the diameter from one side of the tyre to the other too far!
I could go and get all the tyres changed on the current wheels so they are lower profile but I am guessing it would be easier and cheaper to just find some stock wheels.

What is the profile of the tyres on the 17" rims?
The 19" wheels and tyres should pass. They are within 3% of normal for the car. They should also jack up your car a few more mm compared with stock. I do not know how they compare with the ones you tried, without the profile of the others.

Que? I am not sure understand you Harry. If you are required to have the same rubber on all four, and he has the same 255/35-19 rubber on all four, why is that a problem?
The relevance of the placecard is that your total wheel/tyre diameter must be within 3% (+/-) of the diameter calculated from the placecard. I say that the 255/35-19 meet that criterion.
The rubber on one of my cars is not factory width nor on factory wheel size, both being larger. This is completely immaterial because the total diameter is within 3% of factory. The car has been registered by me in the ACT for the last five years.

thanks for the response guys.
i understand both sides of this story as the law states that the rolling diameter of a wheel cant exceed 1 inch of the rolling diameter of standard wheel size.
In theory then a 19inch wheel with a lower profile tyre can still meet these requirements.
In practice though as Harry states, Dickson are notorious for failing wheels even though they fall within the guidlines.
For this reason I think I might avoid the risk and try to get my hands on a set of the stock 16inch rims.

why are you taking it over dickson? there are heaps of authorized inspection stations around that are not stupid old under paid men, that get there kicks from failing cars.

Here you are everyone, the good oil, officially. Those from NSW, VIC and QLD may look up their own regulations, although they will not differ much from these.
National Code of Practice for Light Vehicle Modifications The Federal Government is currently attempting to get all states and territories to adopt this code, which includes regulations for alternative wheels and tyres, in Section LS, Part 4. Currently Tasmania, South Australia, A.C.T., and Western Australia have adopted this code of practice.
TYRES Overall Diameter For passenger cars or passenger car derivatives, The overall diameter of the wheel and tyre combination must be no more than 15mm larger and not more than 26mm smaller than that of any tyre designated by the vehicle manufacturer for that model.
Tyre Width The maximum tyre width for a car or car derivative must not be more than 1.3 times the vehicle manufacturer's widest optional tyre.
WHEELS Replacement aluminium alloy rims must comply with one of the following standards:
Wheel Industries Association (Australia) - (WIA)
Standards Association Australia (SAA)
Technischer Uberwachungen Verien (TUV)
Japanese Industrial Standard (JIS).
All rims fitted to a front or rear axle must be of the same diameter, offset, width and mounting configuration, except for temporary spares.
Where a two axle vehicle is fitted with different width single tyres, the narrower tyres must not be less than 70% of the width of the wider tyres.
The wheels must be designed for the hub's P.C.D., i.e. no slotting of the stud holes, or re-drilling of hubs and/or stud holes is permitted.
The fitment of wheel spacers between the wheel mounting face and the hub is not permitted unless O.E.
The wheel and tyre must not foul any part of the body or suspension under all operating conditions and must be contained in the bodywork when the wheels are in the straight
ahead position.
WHEEL TRACK The maximum allowable wheel track increase is:
up to 25mm more than the maximum specified by the vehicle manufacturer for passenger car.
Zero for front-wheel-drive vehicles with McPherson struts and negative scrub-radius steering geometry, unless the vehicle manufacturer specifies wider wheel option that provides increased track.
Up to 25mm more than the maximum specified by the vehicle manufacturer for off-road and four wheel drive vehicles, except vehicle fitted with beam axles front and rear, where a wheel track increase of 50mm is allowed.

Yes, you meet the requirements so far as I can see.
Under "Tyres" yours are 8mm larger in diameter (taking a pessimistic view of what "15mm larger" means) and only 1.13x wider than a stock 225/55-16 which was a factory fitting on the TT and option on the V8.
Under "Wheels" you will have to tell me that they meet the standards, do not foul or protrude beyond the bodywork and you have no spacers etc.
Wheel track should be fine provided you do not have an unusual offset.
Still, you have to convince an inspector of this, not me, as others have reminded me. Given you have gone to the pits at Dickson it would probably be considered "forum shopping" to go elsewhere but it may still be worthwhile to find an authorised inspector (see www.rego.act.gov.au) and ask them whether in their view your wheels and tyres would pass. Armed with that, you can return to Dickson more assuredly.
Just so long as you can jack the car up a bit that is

Oh, and you also meet the rule which I did not publish, that total speedo error may not exceed 10%. With the change you have your speedo should be about bang on or slightly under-read.
Incidentally, that 10% error allowance is probably why ACT police normally wait for +10% + 1Km/h before booking you.
Tuesday, November 25, 2008 - 09:33 am, by: Andrew Magee(1jz25tt)
ok so the good news is I dont use spacers of any kind, the offset on my wheels is not unusual and they dont protrude from the body.
In this case I think I might head down to Ultimate tunes armed with the inspection report and put the other wheels back on and see how I go.
the car is borderline too low also but when I say borderline I mean its within 5mm and only at one point of the exhaust. I actually spoke to ultimate tunes a while back before I took it in and they said that if I was to take it there the only thing they wanted to make sure of was that it wasnt too loud.
I think I might head in there and see them in the next few days.

Your standard wheels raise you 4mm compared with Stock.
What was the profile on the tyres with the 17" Aurion wheels please? With that I can tell you the height difference between your last test and the next one.

Hi guys,
restarting this post as I am getting pretty desperate!
I think I am ok for wheels now but I really need a set of stock springs to raise the car.
The lowest point is the center section of the exhaust and to have it modified will be a lot more expensive than finding some standard springs and having them put in.

I saw you driving a couple of days ago at the moat st lights? I think it's been 2 weeks. like I told you already you dont need to goto dickson just email me and ill tell you where to go.

Different states have different rules..Up here anything older then ten years has to go over the pits every year (I think its almost the same in NSW but you guys can just get a road-worthy anywhere and present it..)The pits up here have a pit that has lips of 95 mm and if you hit it back up and go away !! A local car wash has under-body wash so most go there before the pits..Just in case....The headlight board is then placed in front of the vehicle.this measures direction and difussion allowances .even down to Aux lights..(Damm new fan-dangled stuff)The Braking rollers run at 20 klm's and all brakes must meet a certain criteria.even the hand brake .BEWARE monster Tacho's..If there is a doubt of noise you will be asked to run your engine at 1/2 redline..and the test rig is VERY ACCURATE...to a tenth of a Decibal !!
