rules change depending on what state you're in. up here in qld, I can get 18's on my VR, as long as they're no wider than 7.5" any taller or wider requires and engineers report.
AFAIK You can have any size wheel you want no matter where you live, but excessive increases in hieght or width will need certification

Speaking proper english will also help you out, i mean it's not that hard to spell correctly is it?

And with rim size it is all dependent on what state you live in, so tell us, then we will be able to tell you the exact rule that applies to you.

After doing a quick search, WA rules are as follows:

# Rim width must not exceed the maximum rim width specified by the manufacturer by more than 25mm (1") (for passenger vehicles manufactured after 1st January 1973, the manufacturers rim width shall be taken as that specified on the tyre placard).

In any event, rim width shall not exceed 177.8 mm (7") unless specified by the manufacturer as standard equipment for the vehicle in question. No increase in rim width is permitted for vehicles fitted with original equipment rims in excess of 177.8 mm (7") width.

# The wheel is contained completely within the body work of the vehicle which includes acceptable flares.

# The wheel does not foul any part of the body or suspension under all conditions of travel

# The vehicle handling is not impaired in any way.

# The tyre to rim fitment must be in accordance with the Tyre and Rim Association Manual.

# Rim diameters must be the same as specified by the manufacturer.

# The wheel must be one designed for use with the vehicle with respect to bolt pitch circle and wheel nut tapers

# The track must not be increased by more than 25mm (1") over the maximum specified by the manufacturer.etc.

# All wheels must be the same size, profile and bolt pattern.

# Vehicles required to comply with Australian Design Rule 24, "Tyre & Rim Selection" must continue to comply with this Design Rule (contact the Department of Transport and Regional Services for more details).

# The fitment of so called "plus one" and "plus two" and tyres is acceptable providing :

* the overall diameter of the large rims fitted with the lower profile tyres do not exceed the overall diameter

* all tyres and rims fitted to the vehicle are of the same size and profile

* with the exemption of item (f), the tyres and rims are in conformity with the requirements specified above in items (a) to (j).

# Reducing the wheel track less than the original manufacturers specification is not permitted, as this may reduce vehicle stability.

So basically, WA only lets 1" above the largest size on your tyre placard ... ouch, that has to hurt.
