Thanks for the link. What has me stumped is there are quite a few there which say that the rule ceased after a certain date. What the heck does this mean especially with ADR 24, Rim and Tyre Selection?
May have been replaced with an Australian Standard...??? May be regulated by individual state regulations...??? The NSW RTA has a guideline for alternate wheels and tyres, this may be why it has gone... Guidelines for alternative wheels and tyres
