(This information is provided as is, I have just spent a lot of time on google and speaking to a few people, it may well be all wrong)
It seems that there is an underlying law that you cannot increase the diameter of a tyre/rim more than 15mm in VIC (not sure about other states)
It also seems no one does anything about it. Last Saturday my mate took my orginal tyres and tried to get them put onto his Triton ute, he was knocked back by 2 places because they are not allowed to make the car un road worthy. He found another guy and he did it for cash I think.
So I started to google it and found that it's a well known thing that everyone seems to ignore. Tyre guys, car dealers (if they even know) and even insurance company's. I rang RACV and asked the guy if I was ok, he told me it was all fine until I showed him a link on the VRoads site. He was telling me how his mate has a wrangler with 37's and 3.5" lift and they have a ball. After reading the pdf he didn't know what to tell me. He couldn't record the mod details in his system as they only require the car to be road worthy. He even suggested I take it to a RACV tester and get it passed there.
I don't care from getting pulled over point of view, it's purely insurance. Even he said he has never heard of a claim being rejected on a 4wd because of big tyres.
Look at section 8 in the PDF

There is a National standard thing as well that says you can have 50mm for 4wd's but it is not relevant because it would appear it has not been accepted by the states and become law, it's just a proposal and has been like it for approx 5 years.
I spoke to a mate that loves Wranglers and he knew all about this 15mm rule and he was looking at getting one and he had spoken with an engineer to find out what was involved in bigger tyres and lift. Apparently because they have Dana axles or something and Dana will send a letter to the engineer stating they are fine with bigger tyres you can actually get the engineers certificate, most company's won't do this apparently.
I was in Syndey yesturday and I think the 15mm applies there as well and I saw a JK with massive mags with low profiles tyes, had to be at least 33" sitting in a jeep car yard. Has to be road worthy to sell it right...
Hopefully some of the guys on here can tell me I'm being a nugget and that JK's came out in Australia with factory fitted 33" tyres (which then means it's legal) It all comes down to the little plate/label in the drivers door. The one thats says what tyres/pressures etc to run.
Like I say , the police don't seem to be an issue and I would have thought if someone had a stack and their insurance had not covered them we would have had to hear about it on here for sure. (or another forum) Thats all I care about, cause my luck would be that if I need insurance it's because I side swiped a car carrier and caused it to roll and it was fully loaded with Audi A6's or something....
It's like it is some law that no one cares or acknowledges anymore.
Like this one.
Its an offence to drive a dog or goat harnessed or attached to a vehicle in a public place (Summary Offences Act 1966)
(How are you suppose to get home after a big night at the pub, your horse can't lay at your feet while you get blind...)
