Need some guidance here

[outback]

Getting spares other than through Nissan. I want about 2 more rims. They are like hens teeth.

[MudRunnerTD]

It fails on 2 counts: goes beyond the allowed off set measurment and also over steps the max allowed track width.
At present I have not seen any rims that fit the requirements. All of the Gecko rims,16s & 17s, have a -13 off set.
Looks like I get stuck with Nissan rims

To be honest mate I think you are trying WAY TOO HARD. Take the academic hat off and this becomes a simple discussion.

You went to allot of trouble to alter your speedo reading. Very few, if anyone else would have bothered. Infact as stated above, as others have changed tyres to a larger rolling diameter it has altered the speedo in the same direction. The argument of the cost of your gig over a set of tyres is nill as they were buying he tyres anyway! So are you! And now your speedo will auto correction and the modification will be the stickler.!!

Most people do the speedo correction I their head mate and know that 97 =100 after calibrating their speedo reading off their GPS! You have more than 1 GPS in your car so surely the speedo correctness is irrelevant?? Surely?

I think you would be having a VERY BAD DAY if you got pinged for running 16" rim in a neg 6 to neg 13 offset with a set of 285s on them. It just seems like a No Issue to me??

Anyone and everyone that is running a 16" rim on a GUIV or later (read HEAPS of people!) have a rego and police problem! Maybe in a dogs world??

If it all gets too hard for you then just stay with the 17s and fit a 285 to the Nissan wheels. The worst that might happen is you scratch them off road.

Please check your local roads and Traffic regarding the State laws on tyre size v total combined lift before proceeding.

Kind regards

Actually there was in reality little trouble in doing the spedo corrections. Just getting parts. A quick web search, 'nissan patrol spedo errors', came up with the answer, which was over at patrol4x4.com, thread by MarcusParcus titled "The CORRECT way to Calibrate your speedo". Also a quick look at the tech library there came up with the ref "ZD30 Y61 Reference Document" by Aksniss, which also covered the issue.

Nothing academic here at all. Besides why buy new set of tyres etc to make the change when I had just put on a new set?

Tyre changing or changing the pinion speedometer gear are but solutions to a basic problem built into the computer in the GU. It is set for a tyre diameter about 33 inches. What Nissan say you should use for tyre size does not provide that diameter. What they say to use for their 8JJx17 rim is 275/65R17 but that provides a diameter of only 31 inches. Hence the sped errors.
The on board computer sets the spedo to about 4-5 Km/h faster that actual road speed, that is the computers detected speed from the gear box. That detail comes from Nissan and cross checked by the Nissan service people here in town.

As far as the police goes I would prefer to avoid dealing with that. Enough stupid examples of ladies being book for unsecured load because that had their hand bag on the passenger front seat, not to mention defects for trivial things as no water in the wind screen washer bottle, is enough to want me to stay away from anything that may attract some over zealous police person.

I get enough hassles hauling legal loads of hay around with out providing them with additional thing to be picky about thanks.

As for worrying about scratching the nice Nissan rims, so what, they get scratched every time I drive in my paddocks.

I was looking at steel rims due to what has been suggested within this thread. If I have to use Nissan rims so what, its just a case of getting extras, though not exactly easy.

As for checking the local state regs I have and posted a link to their web site.

That link again just incase:

So putting a 16 or 17 rim with a -13 off set puts me in the illegal situation both with respect to maximum off set change and also final track width as per that set of regulations.

As Kallen Westbrook said in his post earlier:
"Well it will change it as you moving the mounting point from 10mm outside of centre to inside by 13. So basically you moving your tyre out 1 inch (23mm).
Your track will be 2 inches wider total (1" either side) and I think this falls outside regulation."

Yes unfortunately we live in the nanny state.. this whole national come together with rules was a joke, nothing changed...

There are plenty of rims that will fit your car, you just have to find them.

As for going to 16", check you have clearance between rim and rotor to make the change.. it maybe an option.

Id pop down to a few local tyre joints and get them to do the work.. tell them what your after, and the size you want and get them to come up with a few options and best price.
