Re: 10 Inch Wide Rims
go to your local motor authority website and look at the rules regarding widths. In NSW, no tyres are to be more than 2in wider than the max avilable from factory. Also, overall vehicle track may not increase more than 2in (max allowable without engineers certificate is 1in). Under no circumstances is the wheel to come into contact with any part of the car (thats at ANY steering angle and ANY suspension extension- all the way down or completely bottomed out.)
I imagine most of this will be the same for the ACT...
