        (b)     was built after 1972; and

        (c)     has a GVM not over 4.5 tonnes.

    (2)     However, this rule does not apply to a tyre if the tyre:

        (a)     is recommended by the vehicle builder as suitable for limited use on the vehicle in special circumstances at a speed less than the speed applying to the vehicle under subrule (3); or

        (b)     is being used in an emergency as a temporary replacement for a tyre complying with this rule.

    (3)     A tyre fitted to a motor vehicle must, when first manufactured, have been rated by the tyre manufacturer as suitable for road use at the lesser of:

        (a)     a speed of at least:

            (i)     for a car with special features for off-road use – 140 kilometres an hour; or

            (ii)     for another car – 180 kilometres an hour; or

            (iii)     for another motor vehicle – 120 kilometres an hour; and

        (b)     the vehicle's top speed.

Example for paragraph (a)(i)

    (4)     This rule applies to a vehicle instead of the tyre speed category requirements in the relevant ADR.
