Does anyone know what the legal requirements are for wheel sizes in SA?

What can be put on a Magna?

2 inches larger diameter, 1 inch wider.

i think it has to also be with in 5% of the total diamater...

oh and theres already a thread bout this pretty much...

From the big phat rule book:

(i) Vehicles manufactured on or after 1 January 1973 (ADR 24) are not permitted to increase or decrease the diameter of the wheel by more than 50 mm than the largest or smallest wheel listed on the tyre placard.

(j) The overall diameter of a wheel and tyre fitted to a vehicle manufactured on or after 1 January 1973 (ADR 24) 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. Specifications for overall tyre diameters are listed in the Tyre and Rim Standards Manual, issued by the Tyre and Rim Association of Australia.

When selecting aftermarket wheel rims for a motor vehicle, ensure that the offset of the rim does not vary by more than 13mm from the original rim fitted by the vehicle manufacturer. This will ensure that the wheel track is not increased by more than 26mm beyond the maximum specified by the vehicle manufacturer.

What does this mean?

RIM DIAMETER +/- 50mm stock
TYRE DIAMATER +/- 15mm stock
TRACK +/- 26mm (and can't come out from further than the body work)

Thank you! Come again!
