7% over biggest original fitted tyre in NSW ; can be closer to 55mm larger in diameter

Yeah, it seems I was wrong about the +20mm being ok in every state

I was under the impression that with the adoption of the National Code of Practice last year that the allowed increase to a 4WD tyre was now +50mm to the largest manufacturers option, on a D2 this brings you up to a 31" tyre, so 245/75R16 is legal.

I know that this is the case in QLD and I believed this was adopted by all states, some other items such as suspension lifts have been amended state to state though with the NCOP allowing +75mm suspension, however QLD has brought that back to +50mm.

In QLD without engineering approval you can legally go +50mm suspension and +50mm tyre diameter (+25mm radius). This gives a total maximum lift over factory of +75mm.

Yep NSW has finally adopted national code
