    started a topic State by State - Tyre & Lift Regulations

    State by State - Tyre & Lift Regulations

    The aim of this thread is to place the regulations from each state that relates to legal maximum tyre size increase and suspension lift.

    Feel free to add and correct any info with links and a cut and paste of the relevant section.

    I hope that this thread will help others decide on what tyre and suspension mods to go for and whether an engineer's certificate is required.

    In SA you can go 50mm larger with tyres. It's on the govt. website under "suspension Modifications" rather than the "wheels and tyres" heading where you'd assume it would be.
    Finally found it. Couldn't find it when you notified me earlier. Thank you.

    When is this confirmed to be legal?
    Quote from the Minister

    "I’m delighted to announce I’ve approved for gazettal two new light vehicle standards. The first is titled the Light Vehicle Modifications Manual – Suspension an...d Ride Height (also known as the ‘Suspension Manual’), while the second is called the Vehicle Standards Information 60: Carrying Motorised Mobility Devices and Motor Cycles on Vehicles.
    These standards were developed by the NSW Vehicle Standards Working Group, a committee I established in 2012 to allow motor enthusiasts direct input in formulating vehicle-related policies and regulations in NSW."

    I think that means as of Now.

    Difference = 28mm = 3.6% - which is under the 7% legal maximum quoted above, and therefore OK in NSW.
    i guess I missed the boat on that one. Awesome, 70 series it will be then.

    There's probably a website somewhere that points to NSW adopting the NCOP or some variation of it. If there is, please post here so that the info can be updated.

    The overall diameter of a wheel and tyre fitted to a vehicle must not be more than 15 mm greater than the largest tyre size listed on the tyre placard and not more than 15 mm less than the smallest tyre size listed on the placard.
    What size tyre can you get that is only 15mm larger in diameter? It appears that even a 265/70 is illegal in SA.

    Andrew, great thread. Can you add track changes to that too please. Also ( and I haven't checked lately) those Qld specs only apply to vehicles without ESC, those with are limited to 75mm total lift. I will check again when I get a chance.
