WA Road Laws Question

[mcnamg]

Just a Quick Question for anyone who knows about WA's licencing rules.

What is the rule about the largest size of rim you can legally fit to a car? How many inches can you go up in size from the standard sizes fitted to a vehicle?

If you want to go larger can you get it engineer certified?

i believe its 2inches larger than the standard rim is legal, any more and u could cop a sticker

Sharons car passed with 10inch wide rims on an R32 if that helps.

Ring up the DPI (Dept of Planning and Infrastructure) or www.dpi.wa.gov.au. They can provide information on mods.

Yes best to ring DPI, I rang regarding size difference between front and back cause I was worried about having 8" (235) on the front and 9" (255) on the rear. They told me as long as it wasn't more than 10% difference it was ok. Also that the car could take what was specified on the side panel of your car (inside your door somewhere). No sure if the panel bit is true though!

Anyone else know?

when i went over the pits the last time they told me i could only go 1" larger than what was on the tyre placard on my car

[Jayhawk]

As per DPI. You can go 2 inches larger than the standard rims that came with your car. The size of the rim that came with your car is outlined on the placard just as you open the driver's side door.

Width I'm not sure. But I know that if you go larger you are suppose to maintain the same rolling diameter so that your speedo isn't out of sync. In that case, the width must be proportional to your increase.

how do all these 4wd's that you see rolling around on 22inch rims get away with it?

is there a different rule for 4wds?

can you get them certified by an engineer?

Why dont you all make up your own tyre placards then? Mines just chepo sticker that was made on a bubblejet printer by the looks of it.

no officer it really did come out with 20by 14 wheels on it check the placard teehee

its 2" larger than standard and i think 2" wider than standard up to 7" and no wider than 7" unless it came with wider standard in which case you cant have any wider. you can get engineers approval but its not really worth it coz the pits dont really care. i have engineers approval for mine coz i got it at the same time as a bunch of other stuff.
