Getting 33's licenced in NSW

[rutmutt]

Hey.

I have a set of 33's on my 110 and have been told that these are not legal in NSW. I am relocating there from WA and was wondering what is actually involved in getting them engineered? also rough cost? or is it easier to go buy a set of street tyres and put them on when I have the vehicle relicensed in NSW?

cheers.

Theres plenty of cars up here with 33s on them i will be putting them on my series 3 latter in the year.Haven't asked about the legalities yet but it can be done most just do it ..

I have attached the applicable RTA document. See bottom of page 2. You need an engineering certificate if tyres are great than 15 mm over what the manufacturer specified.

cost me $400 for engineers cert on my car..

Of course some people fit 255/85/16's in lieu of 235/85's as they look really similar and just wing it..........

I had my Defender over the pits twice to get the numbers sorted and no one said a thing,If the vehicle is jacked up and covered in bling bling they will look closely but if it is washed and looked after like Rick said they most likely will turn a blind eye. Pat

Its a very curly one this... The vehicle is well up to 33's and I can assure you it's safe. Sadly it all goes by the tyre placard.:( To be legal you will need to get it engineered:(

I have a set of 33x12.5x15's on my Disco and a set of 7.50x16's on my SeriesIII and they are exactly the same height so why all the hassle, Regards Frank.

[dullbird]

because a discovery never came out with 33's on it from factory

Hey.

I think you will find that 33s would have been not legal in WA as well without engineering.

[rutmutt]

You know you could be right.

I've never bothered to check as it's already licensed here and we don't put our vehicles over the pits at all. But because I will need to change my rego From WA to NSW i assume it will need to be inspected. At the moment I am running 255/85/R16 on my defender 110 and can leave it in WA rego for a while but eventually i will have to get it changed.

So i take it from these comments that i do not need to have any gearing (etc) changed.. just get an automotive engineer to sign it off as safe? so the only cost would be paying the engineers fees?

thanks for the help guys.

thanks for the help guys. The engineer will likely want an emergency brake test done with the front circuit out, check the overall offset and may ask lots of questions on why you need the bigger tyres.:eek: In my case a few measurements were taken of the front end as well.

235/85/16 = about 32"
255/85/16 = about 33.5"

In WA you are still legal as long as you have not lifted the vehicle. 2" lift is okay. Although, I think they have some "approved in principal" thing. But this is not engineering

[rutmutt]

Yeah we can do Lifts of 2" in WA without any hassle at all.. any higher and they need to be engineer certified.

My 110 is only running 1" Lift so that shouldn't be a problem in NSW either.. just the tyres.

[Bush65]

In my eyes, 33" tyres look appropriate on a Defender, I don't know what is involved with transferring rego from another state to NSW. If it is like the annual pink slip inspection you will probably get away with your tyres. If it like a blue slip inspection, then you probably won't.

However this is going to change in NSW, I'm not sure when (I expect before end of year), but pink slips are going to change. When this change to pink slips is introduced, modifications to tyre size, lifts, etc. will have to be approved on your vehicle's registration or it will fail the annual pink slip registration inspection.

A blue slip will be ok to get lifts up to 50 mm approved, but higher lifts and tyres larger than 15mm over the largest placard size will require a certificate from an engineering signatory.

You will need a speedo check as well, and if your speedo is out you will need a correction unit fitted.

It's a blue slip inspection for interstate rego transfer.

The 15mm tyre size change is appropriate for a Civic or Fiesta, but it's a shame someone didn't have some nous and declare it a % instead, but we all know how smart some of the decisions are by the NSW RTA, eg the turbo/supercharger restrictions on P platers that apply to cars like the Kompressor Mercs that have lower specific power outputs than a 6 cylinder Falcon.......

But 255's correct a Defender speedo :D

[dullbird]

doesn't matter still need proof it has been checked..

my 245's correct my disco too:)

only costs 50 bux by the way
