Legal Rolling Diameter - Queensland

[saa3011]

Hi all,

I know it's been asked before, but does anyone have an update on when the Qld regs will be changed to incorporate the Australian Code of Practice for Light Vehicle Mods?

At present 15mm increase in OD is all that is legal (15mm NSW, 50mm Vic and I think 50mm WA).

Having researched Mickey Thompson themselves have confirmed they have no legal muddies for a Patrol, and Cooper appears the same (although they seem to have one A/T).

Doesn't matter what rim size, or tyre width - I would like to get some muddies and use on the Qld registered Patrol, but not until legal (too much insurance risk).

Cheers

VSB15 is going through parliament at the moment and it allows for a 50mm increase over OEM to bring it into line with other State based legislation.

Thanks Bigrig,

I've sent the following to QLD Transport - will post their response when (if) I receive one.

Good Morning

The issue of rolling diameter of tyres on light vehicles has been ongoing for some time.

Can you please provide an update, and anticipated timeframe for the following note;

Note: The National Code of Practice – Light Vehicle Construction and Modification has been finalised by the Australian Motor Vehicle Certification Board and will soon replace the Queensland Code of Practice: Light Motor Vehicles.

This note is located on the following page;

http://www.tmr.qld.gov.au/Safety/Veh...fications.aspx

I would appreciate advice as to what "soon" means, and what process the Code of Practice is going through within the Queensland Government/Parliament in order to put this Code into effect.

Thank you

Good on you mate. Light modifications guideline specifically relates to VSB14 I believe ...

Only persistent and consistent communication from multiple members of the public (and I mean thousands upon thousands) it appears is the way to get any traction on these discussions ...

I sent Qld Transport an email recently to see if I could get a date as to when the National Code of Practice - VSB14, would be put into place up here as it was time for new tyres and I really wanted 33's..

From what I can gather this VSB14 has been "about to be implemented" since 2010.

Their response was very vague - basically saying VSB14 is currently under review and if it does pass through, it's likely that that NOT ALL standards will pass through. No dates or even mention that it could be soon.

I bought a new set of 31's on Friday.

Sorry for the hijack but does this mean 285 75 16r (i think thats 33's in old language) are illegal on a gu patrol? I'm confuddled

I believe they are Legal on a GU but illegal on a GQ

Don't think this is true for the GU either as I believe the standard OEM tyre size is a 275/65/R17 (785 OD).
That would make the 285/75/R16 (833 OD +48)
The 265/75/R16 All Terrain (803 OD) +18
The 265/75/R16 Mud terrain (813 OD) +28
* based on Cooper Tyre sizes. Varies slightly between brands and tread depth.

Theoretically even the 265/75/R16 would be illegal (greater than +15) if the cops pulled you over in the first few thousand Kms. Most Cops though doesn't seem to pull you over for anything smaller than a 35".

However as always it is your insurance company that will sting you. They are not required to pay out on vehicles found to be "defective" or "un-roadworthy". So you may find yourself up for the expenses of all parties involved.
I have heard of some people being stung even when they didn't think they were at fault as the insurance company could prove the mods reduced the vehicle ability to stop/avoid the incident.

Just check it out before you go ahead with purchases. Tyre placard is in the glove box.

Happy to be corrected with other figures if people have them.

275/65/r17 is 31.1 inches
285/75/r16 is 32.8 inches so 1.7 inches differences
So yes illegal in some states but ok in others by the OP. I run 285/75/r16 on my gu and havent had any issues with the authorities but i may look into this as well for insurance purposes cheers.
