Are 17" illegal!?!??!

The 2 most important rules for NSW are these...

1. the rolling diameter for the entire wheel/tyre combination mustn't increase by more than 15mm over the largest optional wheel/tyre combination available for your specific model (CXi, GLi etc.).

2. the width of the rim must not increase by more than 1 inch/26mm over the largest optional wheel/tyre combination available for your model.

The rest of the regulations can be found HERE on the RTA website. Download VSI 9 and read the section on alternate wheels and tyres.

To help anyone who is mathematically challenged (like me), HERE is a JAVA calculator which lets you compare the specs of the wheels you have against the wheels you want (just put in the relevant sizes) and it will also give you an estimate of how much your speedo will be out by with the new wheel specs.

PS: To answer the original question, on an EK1, 17s will be illegal unless they are 6.5 inches wide (I'm guessing most will be at least 7 inches wide) since the stock wheels are only 5.5 inches wide...

erm, so if I buy an Accord Euro Std with 16". can I legally put on 18" ?

Surely if the Euro Lux takes 17", the Std can take 18" no probs... ?

it depends on the placard that shows rim sizes

Use your tyre placard, use the above calculator and see which stock wheel/tyre combination has the largest rolling diameter.

You may find that if you have 235/45R17 as an option, you may legally fit 225/30R20's!! They have exactly the same rolling diameter and would be perfectly legal in NSW.

I have 215/70R15 as an option on my Nissan X-Trail, therefore, I could fit 255/35R20 and be 4mm larger rolling diameter.

Basically, if you keep a tyre phamphlet in your car that shows the the stock tyre diameter and the new tyre diameter that proves they are legitimate, along with a printed out copy of the above RTA ruling, the RTA/Police/Pink Slip inspectors should leave you alone for tyre/rim defects.

so the only way to have 17" on legally is to have the following combo??

17"x6.5" (1" wider than stock) with 205/35/17 rubber(overall diameter few mm smaller than stock)

Regardless....im prolly a bit screwed since i can't just bullshit and say stock rim width is 6" (when its 5.5"....although im not 100% sure)...which makes 17"x7" legal, and that my 205/40/17 are within 15mm over stock diameter....when in reality they are 20mm over stock diameter.

In saying that, while driving the cops cant exactly see the width of your rims, and they will surely not be able to notice a 5mm difference in my rolling diameter, hence ill just hope i dont attract too much attention to my car.

I have known a guy that had a new tyre placard sticker made up to 'legalise' the rims he wanted to run...

Heres a pic of my car.... cant really see the wheelz dat well but theyre 19z. i'll try n find a side on pic

anyone can if they pay that is - judging by the quality of some rides, I don't think you'll be hassled by the judges if you just make minimum effort! ;)

Don't get me wrong, there are some NICE rides there too! Isn't that right Mzcivc? (btw, that's just a running joke...nothing serious here!)

cheers

Thankz for the commentz! Still some more thingz 2 b dun 2 it. But yea... itz my baby

Yea like EK9 Boi said... anyone can enter.

you can hav what ever size rims you want but u just hav to get an engineers cert and recalibrate your speedo

Wat do yu mean yu need to recalibrate ur speedo?

I dont kno anyone whoz done that
