On Vicroads I can find a summary of all ADRs (its in their VSI section) and which apply to vehicle type and age. I can't actually find the ADRs - just the vicroads info sheets (which are pretty good btw)
So ADR23 requires all tyres to have speed and load marked on the sidewall.....so no swampers?
ADR24 requires you to fit tyres as per the size, speed, load, pressure on the tyre placard.....hence the need for an engineer
Mostly they are only a few lines summaries of each ADR - I could not find the full text so who knows if they say you can change placards etc. One would assume so seeing as how states let you run lower speed rated tyres on most 4wds.
cheers

35" Tyres Illegal in WA - Apparently?
Moderators: toaddog, TWISTY, V8Patrol, Moderators
I went to a Chiropracter last week and while I was getting the treatment he told me about a group of lawyers in Australia who have discovered that any Federal laws in Oz that differ from British law and have not been ratified by British parliament , and apparently there are hundreds,are technically invalid . Apparently our Governor General as the Queens representative is supposed to ratify new Federal laws, but is rarely called upon to do so.
This group who call themselves Caledonia Australis has apparently registered themselves as Australia's true government and claim UN sanction. If there is anything to this, and I admit it sounds like bullshit to me, it would mean that the sky is the limit with regard vehicle modifications. in Britain, Rover built and sold limited series LandRovers with 50" tractor tyres, These trucks were legally registered. You can register tube framed buggies, or put 27 litre Spitfire aeroplane engines in home built creations and register them too. A private owner can legally drive an ex military tank or similar on public roads, and if that vehicle is over 25 years old you dont even have to pay Rego.
This Caledonia Australis group apparently have a website, so I might look it up for a laugh.

The 2 vehicles I had engineered were a 1985 LR County on Volvo portal axles, and a LandRover RangeRover hybrid that was deemed by the engineer to be a 1978 RangeRover. Neither vehicle originally had speed rated tyre placards. but new tyre placards covering the 36"Q78 swampers were provided by the engineer once we proved to him that they were DOT rated from Interco's techncal literature on their website.
There are some instances where an engineer has to call on his training and make qualified judgements and I suggested he do so on quite a few points of conjecture. He charged $1000 for one vehicle and $500 for the other and I made him earn every cent, but I am fully confident that everything is legal and that he didn't turn a blind eye to anything.

This thread is great. Edward I find your argument irritating since I have invested a lot of time and money trying to do modifications within the law. But you have made us all aware that by modifying our vehicles there will always be some responsibility shifted from the manufacturer and onto the owner/ modifyer.
Thats why I want an engineer to look at my vehicle and make sure it is safe, not because I'm scared of anyone sueing me or him or anyone else that greedy suckers want to chase, but because I would not want to live with the thought that I killed or injured someone out of unnecessary and arrogant negligence.
As far as 'breaking the law' goes, apparently pleading ignorance is no excuse, but who really knows what is OK? The states say one thing, the federal another, one engineer says this but another says that, one lawyer will argue and beat another on some little loophole in the law that wasn't covered...
I'll interoret it this way... the ADR's set the guidelines, the engineers will aprove modification within them and the vehicle owner will just have to trust that they do a good job.

Just some interesting parts I copied off the vicroads website:
WHEELS AND TYRES
Replacement wheels and tyres may be fitted provided that they comply with the following requirements:
The width of any replacement rim must not be:
more than 25mm greater than the widest wheel specified by the vehicle manufacturer for that model or vehicle series
Rims, which have been widened, must have no more than one peripheral weld. All welding must be carried out in accordance with recognised engineering standards, and the rims must comply in all respects with specifications contained in the Tyre and Rim Standards Manual published by the Tyre and Rim Association of Australia.
The overall diameter of any replacement rim and tyre must not be:
more than 15mm greater than largest diameter tyre specified by the vehicle manufacturer for that model or vehicle series.
Rim and tyre combinations must be in accordance with the recommendations contained in the Tyre and Rim Standards Manual published by the Tyre and Rim Association of Australia and have a load and speed rating equal to or better than that required by the standards for registration.
The wheels and tyres must not foul any part of the body, suspension, steering or brake components at any position of the suspension travel or steering movement and, when in the straight ahead position, the guard or bodywork of the vehicle must cover the section width of the tyre.
Note: The section width of a tyre is the distance between the outsides of the sidewalls of an inflated tyre excluding any markings, bands or ribs.
The maximum allowable track increase is:
in the case of a front axle-25 mm;
in the case of other rear axles-50 mm;
Spacers between the wheel and hub are not permitted unless provided by the vehicle manufacturer as original equipment.
The stud pattern of the replacement wheel must be the same as the original. Re-drilling wheels, hubs, drums, discs or axle flanges is not permitted. Wheels with slotted stud holes are not permitted.
Aluminium alloy wheels (mags) are acceptable provided they meet the above requirements and are legibly and durably marked to show compliance with one of the following standards:
AS 1638 Australian Standard
DOT Department of Transport USA
JWLT Japanese Light Alloy Wheel Truck and Bus
JWLT Japanese Light Alloy Wheel
JIS Japanese Industry Standard
KBA German TUV Certification
VIA Vehicle Inspection Association Japan
Repaired or damaged alloy wheels are not acceptable.
Extended Chassis - Can I extend the chassis on my truck?
A: Yes, where the chassis is extended at any point forward of the rear axles rear spring hanger or any other major suspension component an Engineers report from an approved Engineer is required.
For chassis extensions to the rear of this point specifically to support the truck body or tray which has its own load bearing frame an engineers report is not needed. However the work should be done by qualified trades people.
Doors - My four wheel drive has removable doors, can I leave them off when driving?
A: VicRoads strongly recommends against this practice, particularly when the vehicle is used on the road. However, if seat belts are fitted the vehicle may be used without the doors fitted.
Q20: Driving Lights - How many headlamps can I have on my motor vehicle?
A: A maximum of six main-beam headlamps are allowed on motor vehicles other than motorcycles. The lamps must be wired so when the dip switch is operated no more than two lamps, showing dipped beams, can be left alight. For further details on lighting requirements see Vehicle Standards Information Sheet No. 10 or Vehicle Standards Bulletin No. 9.
Q26: Flared Mudguards - Can flared mudguards be fitted?
A: Yes, provided there are no hazardous protrusions and the wheel/tyres do not contact the mudguards under any condition of steering or suspension movement, or exceed the allowable track dimensions. For further advice see Vehicle Standards Information Sheet No. 8.
Q30: Roll cages - Can I fit a roll cage to my car?
A: Yes, provided it is heavily padded with a high density impact-absorbing material in any area where a vehicle occupant may strike it in an accident. Also it must not adversely affect the operation of the seat belts and the driver's vision and must not contact the heads of any person who is seated in the normal seating position in the vehicle or prevent people from getting in and out of the vehicle easily. See Vehicle Standards Information No. 28 for more information.
Q31: Seat replacements - Can I change the seats in my car?
A: Yes, however, if the car was manufactured after 1970 the seat must comply with the Australian Design Rules for seat anchorages and if manufactured after 1971 must also comply with the Australian Design Rules for head restraints. An Engineer's report or a compliance plate is required as evidence of the continued compliance. See Vehicle Standards Information No 19 for more information.
Q45: Tubeless Tyres - Can they be repaired using plugs?
A: Yes, if the puncture is in the tread face and not in the side wall or the part of the tyre where the tread turns onto the side wall. The plug must have a mushroom head and be fitted from the inside of the tyre and the hole must be fully sealed. Further information see Vehicle Standards Information Sheet No. 16.
Q47: Spare wheels - Do I need a spare wheel or jack for a road worthiness certificate?
A: No.
Q48: Wide wheels - Can I fit wide wheels and tyres to my car?
A: Yes, in some circumstances if may be possible. For further information see Vehicle Standards Information Sheet No. 8.
Q52: Can I fit extra seatbelts to my motor vehicle?
A: Yes, see Vehicle Standards Information Sheet No. 15.
Q55: Can I raise my vehicle?
A: A vehicle may be lowered or raised provided the clearance between the suspension bump stops is not altered by more than 1/3 of that specified by the manufacturer. In addition, the normal relationship between the front and rear suspension heights must not be unduly affected. If the above dimension is exceeded or the vehicle body is raised separate from the chassis an engineer's report may be required.
