Wheel size law

[calais24/7]

was just wonderong why you have to get a engineers cert. if you get wheels 2" bigger then stock. for example if i wanted 18" vy ss wheels on my vl how much would it cost to get the engineers
btu are the vy ss wheels 18 or 17?

vy ss came with 18s but my brother has 17s so i guess you can get both.

[SAV_117]

vy ss came with both older one is 17's and newer 18's

[ducker85]

I dont know the wheel laws in your state ring the coppers and ask how to do it legal n who to ring to find out more.

thanks guuys for the replies. any idea on the price i should be paying for the 18"s with good tyres say anywhere between 50% + and good wheel condition?
cheers

rough guess id say $800. no idea though.

and im pretty sure the law is 2 inches larger than standard size the car originally came with, including tires.

I am fairly sure that law has changed and now it is just the circumference of the tyre or some rubbish.
