i was just wanderin on how big i can go in rim sizes in Qld on a datto ute is it only 15 or can i go bigger

my post in prior thread about this.
go to the Department of Transport near you and pick up the booklet "MODIFICATIONS- all about modifications to motor vehicles"

in qld you can have any size rim and tyre you like, providing the o/d of the tyres do not exceed that of original equipment.

edit for clarity: "the rim diameter may be varied from the standard sizebut the overall diameter of the tyre must not vary by more than +15 or -26"
it also says nothing about rim width which leads me to beleive you can run any width as long as:
you dont use spacers,
the tyres width does not exceed 1.3 times the vehicle manufacturers widest optional tyre.
and your tyres mustnt hang out past the guards.
