I seem to recall about 6 months or so there were a couple of threads about proposed changes to the legalities of fitment of larger than OE diameter Tyres.

Think it was something about a National Standard

Now I can't find the thread. I've searched every which way.

Can someone point me in the right direction or provide an update

Thanks for the assistance.

I'm assuming this was a Queensland thing Chris, because to my knowledge the States are all all over the place with their laws and regulations. All we can hope for is a (sensible) National Standard someday.

nothing has changed.. although a few states have taken the new laws on board.

If you ring Queensland transport, they will tell you what you can/can't do over the phone,this way you will get 100% correct info,not hear say you found on the internet.
I previously owned a courier(4WD) and the biggest I could go was 15mm higher(diameter) than what was on the tyre placard

This is the link to the proposed national standard. Not sure if there has been any movement on the question. Last I heard it was still max 15mm diameter same or better speed and load rating.

Thanks Graham
This was the doc I was looking for.

It actually specifies a 50mm max increase for off-road passenger and commercial vehicles.

Question now is, what is the stautus of this NCOP.
I'm going to start asking a few questions, wonder if anyone cansave me some time there.

Chris

Don't know were you are located, however in Queensland, the NCOP (national code of practice) has not been adopted and is not expected to be adopted this year (based on email advice from Queensland Transport). Therefore the limit is 15 mm increase in OD.

I understand some of the other states are the same but not sure which...

Thanks for that Mark, you saved me some time.
I thought it was a bit too good to be true.

Sounds as though there is some chance it may yet be adopted in Qld, who knows, we may even get it nationally.
