ok um i have 19s and i know they are illegal now my mate perry has 19s as well but his are legal cos his car came with 17s now what im wondering is if its legal on his car could i fight a fine saying my car has the exactly the same chassis so there is technicaly no problen.
also found out that engineers certificats are worth nothing cos the police can still fine you even if you present one cos even if i got an engineers cert to say my rims are safe the police can still defect me cos the rules state only an inch wider track than standard.

Hey man,

mine came with 16's, i put one of my old rims when i had them up against my 19's and the looked to be the same rolling dimanter

No more than 1" wider in track where track is the distance between the centre of the left wheel and the centre of the right wheel. As long as you have the correct offset for the width of wheel fitted, there should not be a problem (that is, the wheels are not sticking outside the body of the car or hitting the suspension arms).

Diameter wise, there is no limit as long as the overall diameter (wheel + tyre) are within 15mm of the OEM ones.

Thus the combination of the track limit and wheel offset will determine what sort of wheels can be fitted.

Engineers certificates are not meant to state that your illegal mod is fine.

Its to certify that all modifications are infact legal.

They're illegal, you're lucky you didnt smash into a porsche/ferrari/merc etc and have your insurance company laugh at you at stick you with a 60K repair bill.

What's illegal about them? Or have I missed something? You can have any wheel/ tyre combo as long as the OD remains within +-15mm of the original OD. (According to the RTA site) Width of the wheel must not exceed 26mm of the original wheel width.

So what have you got on your car & what was the original wheel/ tyre combo?

my car originaly came with 15/6 inch rims now i have 19/8 so my width is illeagl

also from memory, you can get wider wheels engineered.

It does cost a fair bit, you will also have a shiny new tyre placcard from the engineer.....

no engineer out here in the central west any more the bloke in dubbo shut up shop so id have to drive to sydney but not sure id waste my money the rims have been on for bou 5 months now been pull over for rbts and they have done nothing probably cos im not a hoon.

Wait till you're in an accident.

You'll re-think that statement. Insurance will be void, and if the RTA/Police consider it a red sticker defect, where you shouldnt be driving the car at all, you're in for a lot of problems, as you are technically driving an unregistered/uninsured car :)

yea i no it sucks but i just have to hope and pray i dont but thinking im probably not the only person in the club with illegal rims ay

Which Magna do you have?

In the owners handbook what was the largest available wheel on that model? If I understand correctly, that's the starting point at which you can go bigger. So if there was a 16" x 7" available you can, legally go to an 8" wheel.



Minor changes to wheels
Wheels up to 26mm wider than the largest optional wheel recommended by the vehicle manufacturer for the vehicle can be fitted without the need to notify the RTA.


Someone else can correct me if I'm wrong but the way I read it is that if a 7" width wheel was available as an upgrade, you'll be fine. Why not call the RTA & ask them about it.

1998 magna advance
not sure bout optional wheels anyone know

Optional wheels for that Year were the 16x7 (Sports and Verada models)

And all the guys here are right, if your load rating is below 94, Insurance can deem it unroadworthy and not pay out in the event of an accident. Also if you do not have the rims listed on your policy it will also make it void.

New RTA rules state that so long as the Rolling Diameter is within 15mm each way and no wider then 26mm with no increase in track, they are legal and do not require a Engineers cert.

It is in your best interests to make sure you tyres are correctly loadrated, and also that they are listed on the policy as a modification (dont have to increase it to cover the rims just get them to list it)

So an 8" rim should be fine.

Also, why wouldn't you increase the policy. Should only cost $50 or so more & at least if you do have an accident you'll get some extra $$ to go towards replacing any wheels, if needed.

because some policys dont like aftermarket mods to be added, and if he is young they can charge him a pretty penny for it.

Yep,you should sus out your insurance BEFORE modding.

well my insurence is great at the moment all of my mods apart from my new rims are insured and my premium is just over a grand and i got 50% no claim up so thats no prob
