huh... I just noticed the same question on NissanSilvia.com

did you ask it there as well?

[VB-]

thanks alot roman.

i would recommend anyone who has modifications on their car to print this out and keep a spare copy in the car, and get very familar with it.

p.s i would recommend SAU do something like sticky these sort of important documents.

[VB-]

i also wanted to raise a important question about the document.

this was taken from section 8 in regards to wheel sizes.

it states that wheels are determined illegal is they are above 25mm from the wheel spesified on the car OR car series.

what does vicroads clasify as series?

Series of the Actual car (eg R34 GTR or GTT or GT)

or

Skyline series? (R32 R33 R34) would that include the new R35 then?

if so R32s (which came with 15s) could have wheels as big as 20x10 and be legal?

Personally i always thought of it as

Brand = Nissan

Make = Skyline

Series = R32/R33/R34/R35

Model = GTR/GTT/GTST/GT

discuss

think about WHY they have these rules and that should help you find an answer. vicroads' rationale is for cars to remain safe and roadworthy by not allowing monster wheels to be put on tiny cars, whose chassis/suspension etc wouldn't be able to handle it properly.

how similar is an r32 to an r35? chalk and cheese, but for the GTR label. i doubt very much you'd get away with it on that basis.

i go by the tyre placard, ie. 25mm wider than the widest rim on there.

[180Roman]

i'd say

Make: Nissan

Model: Skyline

Serries: R32/R33/R34

so you can follow form your serries, but technicaly there is no restrictions if you go and get an engeneering certificate for you wheels

your point about a r32 compared to a r35 is taken is but i think your failing to see the point here.

bigger wheels half the time are used to help handle better. its half the reason why you see monster GTRs with something like 18x11 wheels despite then having no where near that big from factory. wether your using drag applications or track, sometimes you jsut gotta go bigger.

i would like bigger wheels on my car and would like knowing its legal........thats all

Always thought it was,

Make: Nissan

Model: Skyline

Series: R32/33/34

In the VicRoads documents, I've always translated the 'widest for that vehicle series' as in the widest that series has got. For example the R32 GTSt's only got 15x6.5" wheels where as the GTR's got the 15x8". The 15x8 was the widest from that series (R32) so you could legally go up to 9" wide (both on the GTSt and GTR) and whatever diameter as long as it's 15mm within factory rolling diameter (total, both tyre and wheel).

No idea if that's correct or made sense, but I always thought it was like that.

Umm there is one...

Its called the EPA/RWC thread in this very section thats been there since Feb 2007.

As for the actual VicRoads VSI documents, there is no point uploading them.

You should always download from the website if wanting to view them incase there are ammendments and so on.

So uploading the to the forum itself would not be beneficial on the chance it proves old/outdated information

Don't quote me as I'm not certain, but back in my FordForums days, I remember everyone saying that they could run XX size and diameter wheels on their base model Falcons etc due to the XR's in that series having XX size wheels.

I think it goes off the largest available factory option for that series. So for example a BF Typhoon came with 18's, but optional 19's therefore you could get away with 21's if the rest of the dimensions were within the guidelines...

As far as translating that to Skylines, it's only really the 34 that has anything 2" bigger from GT-R to GT-T, with 33 GTR's only being 1" bigger than GTS-T's, but that'd still allow 33's to run 19's as long as the widths and tyre sizes were within the guidelines...

Think there's also another rule of any wheel/tire upgrade having to be within 15mm of the largest/smallest factory option wheel/tire package for that car...(included smallest as you can't run 13's on a car that should have 17's etc)

[VB-]

theoretically you were to go on the bases that 15mm was the largest/smallest size package, you could essentially have 25" wheels so long as the tyre is small enough to compensate for the 15mm no?

I think there's more than the 1 rule as far as wheels go...So you might be within the 15mm rule but outside the other ruling as far as wheel size goes...From memory its 2" up/down on the largest/smallest factory option

[SKYL1N]

very interesting read. espech about the bonnet scoops.

[VB-]

wat i would like to know is what vicroads clasify as series.

if indeed they look apon series like like dezz said. base model falcons being compared to high end XR6s, it should apply with skylines aswell.

the new R35 sports 20 x 9.5" (front) and 20 x 10.5" (rear) .

which would hopefully mean i can run my 19x11s on my car

i think what dezz meant was that you could run the width out of your serries, so if you have an R33, you have to keep to the max width that was available, so that would mean R33 GTR size wheels, plus that 15mm rule

[madbung]

It's all in plain English..

Falcon, say a Ba...regardless of spec it's still a BA series falcon. So if the largest diameter rim is 19 x 35 x 235 from the factory you may go 15mm oversize in rolling diameter and up to 25mm in width.

Skyline, r3- series whatever....blah blah, same deal, regardless gtr,gtst,gts ect you can go 15mm taller in rolling diameter and 25mm wider over factory spec

Yep, thats what I meant. Not that you can go off what the R35 has....

So basically all GTS-T owners would go off GTR specs as they're going to allow you to run the largest wheels

As for fords, EF-EL would go off EF-EL XR's, AU off AU (series 1, 2 and 3) XR's and so on

yes wider wheels can give you more traction, but what ric is trying to say is that cars are designed with those wheels in mind... so certain suspension components are also engineered to work in with the standard wheels.. and a large change from standard specifications can have adverse affects, such as the wheel bearings.. if you go too wide with a very drastic offset, you'll start to load the wheel bearing beyong thier engineered tolerances! so the limitations imposed by vicroads and adr, are not there to stop you having fun with which wheels you want to put on your car, but as a safety guideline.

[R31Nismoid]

^^ or even snap wheel studs and so on if the car is too low and rims dont sit right etc.

There is a can of worms so to speak about all the possible dangers... ye you might not be bad yourself, but this is the majority of society and some of the stuff you see on the roads is a clear reason why these laws are there as they are just dangerous
