35"s id say yeah they'll defect you suspension lift i think is limited at 2in

In Qld it is as per the ADRs which read along the lines of no more than 15mm increase in overall diameter from standard. They also say no more than 25mm increase in track in an IFS and 500 track increase in a solid axle.

500 on a solid axle!! I think he means 50mm

[bigbrowndog]

Cops here in Townsville say 1 inch bigger than standard [ classed as 16 inch.] Nothing outside the guards unless flares cover the tyre. Really depends if you drive sensible but if you are oversize then in an accident you are toast.
Contact Qld transport or their web site. cheers

No matter who you talk to this is still a very grey area. I have a mate at a tyre shop and he says he's seen the police defecting for wider tyres arguing that it is increasing track when of course it isn't. In Qld you can't mod plate tyres yet I know a guy that was sent over the pits with 35's, 4" lift, modified trailing arms, adjustable panhards etc and no mod plate. Now he has a letter from the "pits" saying his car is fine. All he really had to do was get a certification on the welding of his trailing arms whis was done where he worked.

35's are definately illegal. 15mm increase in diameter as mentioned is the key but that technically is 15mm over the largest tyre fitted by teh manufacturer which means 15mm over a 7.50R 16 split rim which means a 285/75x16 should just scrape in as does a 305/70x16. Rim diameter is a + 2 fitment so you can go 2" larger in wheel diameter over the largest offering by the manufacturer so 18's are legal on an 80 Series assuming you have the acceptable tyre size to suit.

Yet there are still other grey areas. My mate showed me a code that says you cannot change wheels and tyre specs AT ALL on any commerical load carrying vehicle and this included utes. So even if you keep your heights right, your speed rating and load ratings right you cannot even put alloys of the standard size on a Commodore ute for example. I suppose that would read to Hilux's etc as well. Not sure where this code came from but it's supposed to be fairly recent, unless it's a proposed code.

Yes it's grey area even if you email qld transport it will have some little disclamer on it (can't remeber what it said i emailed them a little while back) also you ask 3 people down there the same Q i'd almost put money on it that you'll get 3 diffrent answers might be best for lift talk to someone who does mod plates they should be upto date with it all and call round don't just talk to the 1 person

I spoke to QLD Transport this week regarding ride heights.

[b]QT answer - Quote[/b] "There are a few mistakes in the modifications guidelines booklet, but that will become easier when the national rules come in at the end of the year, which allow a total of 6 inches increased roof height - this can be made up of suspension, tyres and body lift (based on 2+2+2, but can be 4+1+1 etc)"

how cool is that !!!!!!

i was asking what is standard height for my 60. they didn't know. so there will always be a grey area regarding lifts etc.

That would be cooool.....IF it happens. Could always then just chop the roof down to get ut under the 6" rule

Something like this for a 40.

[PFJ]

what a beast. if only !!!

i think the 'roof' term was just A reference point though..........

Yes I meant 50mm and yur mate is very lucky. The IFS luxs didnt have that size tyre so again different. The commercial vehcile rule you speak of doesnt include 4x4s or commodore utes but one tonne utes only most commo and falcon utes are only 750kg rated making them exempt. It was bought in to screw over the mini truckers. There is no greay area with tyres it refers you to the adrs which are as I stated
