Hello,
I have heard many things, but can anyone confirm that anything over 33" tyres and a 50mm lift is illegal in Qld?
Cheers,
Patrick

well that was prob a bit to short an answewr I felt bad so I did some digging for you.
From thr QLD DOT.
1.the suspension travel in the bump or rebound mode must
not be altered by more than one-third of that specified
by the manufacturer
2.The rims and tyres must not protrude beyond the bodywork
of the vehicle, including flares, when viewed from above and
when the wheels are facing straight ahead.
3.The tyre and rim must not foul wheel arches or suspension
components under any conditions. Steering limit stops should
not be adjusted to reduce the turning circle in order to allow
the fitting of the tyres and rims.
4.The maximum tyre width must not be more than 1.3 times wider
than the vehicle manufacturer’s widest optional tyre. However, in
the case of off-road passenger vehicles fitted with front and rear
beam axles, the maximum tyre width must not be more than
1.5 times larger than the manufacturer’s widest optional tyre.
5.Off-road
passenger vehicles fitted with front and rear beam axles,
may have an increase in track up to 50 mm beyond the
maximum specified by the vehicle manufacturer for the
particular model of vehicle.
6.Vehicles built on or after 1 July 1985 must be fitted with
original wheels or replacement wheels which are indelibly
marked in accordance with approved standards.
These include:
• Standards Australia;
• Wheel Industries Association (Australia);
• Technischer Uberwachungen Verein; and
• Japanese Industrial Standards.
Markings must include diameter, width, offset and the
manufacturer’s trade mark or logo and be located so that
they are readily visible when the wheel is correctly installed
on the vehicle.
With ref to point 1. from QLD DOT;"fully compress the suspension ,then lift the car to let the suspension fully drop. Measure the distance between and then you have got your bump and rebound mode."
Ahhhh now I don't feel so bad

The regs also state that tyre diameter cannot be more than 15mm larger than the largest diameter of wheel and tyre combination offered by the manufacturer. You cannot get an engineer's approval to go larger. 
I think with a Patrol you can fiddle the figures to go to 33" tyres. If you search long and hard enough there was a discussion her a few months back.
The 50mm lift limit is for body lifts. The regs state you must use metal blocks (although people claim to have passed the inspections with HDPE) and Qld Transport do the inspection - not an Authorised Person.

mmm
50mm body lift is legal
50mm suspension lift is legal
As per Bulletin 35 May 2000
Body Lift Kits and Suspension Height Modification
Due to an ever increasing demand for approvals of suspension modifications, Vehicle Standards have released the following policy in regards to this matter.
Body Lift Kits
The maximum allowable height permitted by Queensland Transport has been set at 50millimeteres ( 2 inches).
Suspension Height Modifications
The suspension travel in bump or rebound mode must not be altered by more than one-third of that measurement as specified by the original manufacturer.
It should be noted that both modifications can be performed simultaneously to a vehicle to gain extra vehicle body height but individual specifications must not be exceeded. Modifiers may have to obtain the original bump stop clearances to calculate the allowable acceptable increase. The wheels and tyres fitted to a modified vehicle must continue to compl with the requirements of the Transport Operations ( Road Use Management – Vehicle Standards and Safety ) Regulation 1999.
An individual vehicle modification application to be made to Queensland Transport for body lift kits (blocks between body / cabin and chassis mounts) up to 50 mm in height. Applications must indicate changes made to implement the modification (including steering and braking componentry and materials used in the lift blocks. Body lifts in excess of 50 mm will not be considered.
If acceptable a letter of approval for the installation of a body lift kit will be issued by Queensland Transport
Suspension height modifications carried out in accordance with good engineering practice will be considered acceptable where the suspension travel in the bump or rebound mode is not altered by more than plus or minus one-third of that as specified by the original manufacturer A vehicle modification application will not be required as this is considered to be a self approved modification.
Modifications that involve leaf springs remounted from under axle to over axle are not regarded as an acceptable form of suspension modification and will not be approved

cheers
No problem at all
http://www.4lo.com/calc/gearmetric.htm was the link
And yes i coulda summed it up a bit more. worked out to be 32.8 diameter and 11.2 wide.

You'll find that there are a fair amount of offroaders driving with 33's without any problems - It depends on the tyre placard on your vehicle as you can only have a 'maximum' increase by a certain percentage / mm - there was a write up on this ages ago.
Heres the link.

Big write up in there.. But worthwhile reading as it outlines a fair few things to be considered.

33's
I have 33' muddies on my gq and i drive it daily, as soon as I actually get my adjustable panhard rods then the all the wheels will be under the flares and i've had no problem at all. Stupid thing is the boss at work has a 3" spring lift and 2" body lift and 33" tyres on his gq and thats legal and i've got the 5" spring lift and i'm pretty damn sure thats not legal, bah hambug! stupid rules

you wont have a problem, i think it was the vx saraha was factory optioned with twin diff locks and 285 tyres (or what ever 33 works out to be) so it was an option from toyota and should be on the tyre placard.
