Hey guys and girls, just wondering if anyone knew how much bigger over factory size, rims you are allowed to get. On P plates especially, according to vic roads rules.

Yeah, thanks for posting it, kind of squashes my chances with the dark argents. I'll contact the police and see what they say

XR Lightning is right, cant go bigger than the rolling diameter of the largest allowed on the placard. Some cops go for the old rule, some for the new one

since when do tyre placards have a rolling diameter printed on them?
rolling diameter = diameter of wheel+tyre

Yeah it's all about rolling diameter now. Which makes 20's still legal, as long as the tyre load is correct to the car and the rolling diameter isn't more or less than 15mm than from factory. I've spoken to many tyre and wheel places about it and seen it in print, so if a cop tries to get you on big wheels stand up for yourself.
My mate got his EF defected for too big of wheels and headlights TOO yellow lol. Went to vicroads without touching the car, vicroads said the copper is a dickhead basically, wheels and headlights were both fine.

i never denied the profile,

you claimed that there is no difference in larger wheels to your vehicles ride height, i said there was

i never mentioned what profile sidewall to use i just there was a difference in my wheels

So you just proved nothing relevant. Wrong profile = difference in size = difference in car height.
Well done! Want an award?

Basically? FFS. Its like saying you can run 18s with 4wd spec tyres, of course its going to change the size :banghead:
I told you previously you can run 20s fine on E series and you argued, get over it, you were wrong.
