Re:


So.... I've done more research on max tyre sizes for T31 in NSW and ACT.
ACT = VSB14 NCOP11 Section LS https://infrastructure.gov.au/roads/vehicle_regulation/bulletin/pdf/NCOP11_Section_LS_Tyres_Suspension_Steering_V2_1Jan_2011%20v3.pdf
NSW = VSI09 Rev4 http://www.rms.nsw.gov.au/documents/roads/safety-rules/standards/vsi-09-rev4.pdf

There was talk of going to percentage based tyre size changes, but I haven't found anything (not even in Victoria). Essentially, its 15mm in overall diameter (OD)

The T31 comes with 225/60/17 with an OD of 702mm. The TL/Ti with its 18" has OD of 694mm. The question is whether the TL/Ti can use the OD for the 17" TS/ST, as technically they're different models - follow the advice of your tyre placard.

So, lets say the 702mm applies to ALL x-trails, that means max OD can be 717mm.
There are very few oversize offroad tyres one can go to, without breaking the 15mm limit:
16"
215/70/16 = 707mm: BFG AT KO and KO2 (both in LT) and Bridgestone D697 and Firestone Destination A/T (both non-LT)
235/65/16 = 712mm: nothing A/T, a few passenger and touring tyres like Conti Vanco4Season
17"
235/60/17 = 714mm: Cooper A/T3 (passenger construction)

annnnddd thats about it.

From what I'm hearing, insurance companies have cottoned on to oversize tyres (235/70/16 is VERY noticeable) so now I"m just waiting for the KO2's to be released in Aus next quarter.

Re: Thinking about oversized tyres on T31


Might update my story. I bailed on the whole big wheel idea.
Having a s1 t31 ti the tyre placard states 215 60 17. This in itself is an oddbal size because the later x trails went to 225 60 as stock.
the diameter is 690 on the 215 60 17
here in south aus the rules too are no more than 15mm increase in diameter unless engineered.
I am limited to 225 60 which are 702 in diameter.
I called my insurance company and told them the logic to try and allow me to go 225 65 but got the whole if it aint a legal mod then no coverage in an accident. As said in posts above, because big tyres, lift kits, awnings and bullbars are all the rage these days (like the late 2000s with imports turbos and bovs) insurance assessors go to these mods before anything else.
I cant find load ratings for my 16 inch rims so the above risk aint worth it either.
I sought the opinion of an engineer and it was agreed kn the logic arguement that running a larger tyre can be justified, but I need to pay for a report ($500) and have my car go through the rego office with more time and fees.... For what? 1/2 inch tyre lift...
make matters worse I have been rejected from 4x4 parks due to no low range. I gladly point to the 4x4 knob on the dash. But parks consider this a awd. Simply I cannot use this car to its potential to need bigger tyres or a/t m/t, lt...
I managed to get a set of conti lx sport on a buy 3 get one free deal and they will be ok for towing and sand driving which is about the only off road thing in this state I am allowed to do.
the tyre shop did try to sell me 225 65s and said they were legal. But I think they thought it was a later model. I came clean and said id have the 60s (which were more expensive). I got a family to think about these days. I need to play in the rules... or should have got a series IV

Re:


A bit worrying that the tyre shop tried to sell you 225/65/17 (they tried this on me with my series Iv when they couldn't get 225/60/17 in)
225/60/17 is 702mm
225/6517 is 724mm. I.e definitely not legal

I miss my 235/70/16 tyres but you're right - the insurance companies have cottoned on and are checking these things

Re: Thinking about oversized tyres on T31


My xtrail was purchased with 215/60/17 Tyres.........OD 690mm.
When I purchased new tyres the NSW legal increase was at THAT TIME a maximum of 15mm.

I purchased 225/60/17 ATS tyres....OD 702MM (an increase of 12mm so AT THAT TIME legal
in NSW)

The NSW regulations changed allowing a maximum increase in size of 7%.
refer to:-
Vehicle standards information
PUBLISHED 8 NOVEMBER 2013 | REV. 3
Supersedes VSI No. 6 | Rev. 2.1 | 1 November 2007


Quote.....
WHEELS AND TYRES
Item
Modification
13
Replacement of tyres that change tyre overall diameter by more than 7% of the overall original diameter*. * ’overall original diameter’ means the maximum outside diameter of the largest tyre specified by the vehicle’s original manufacturer as an option for the vehicle, as shown on the vehicle’s tyre placard.


7% of 690mm is 48.3mm. So I could now (IN NSW) purchase 225/65/17 tyres which has OD of 724mm.........(an increase of 34mm from original)

I checked SA regulations and they still say max increase of 15mm. I have not checked any other state/territory regulations

SO CHECK YOUR LOCAL STATE/TERRITORY REGULATIONS for legality

cheers

Re:


Good work Dave.... but honestly - RMS need to get their house in order.
Both VSI 6 and VSI 9 are listed here:
http://www.rms.nsw.gov.au/documents/roads/safety-rules/standards/vsi-06-light-vehicle-modifications.pdf

Both VSI6 (7%) and 9(15mm) talk about OD maximums. From a legal point of view, VSI9 is much more specific and I would say would override VSI6 based on literature detail... but the way these regulatory instruments have been written, they are actually independent of each other... so very confusing.

I'd definitely be getting something in writing. The 7% rule doesn't sound very safe... for a Series IV or V with 225/60/17 (702mm), that would allow 751mm. My old 235/70/16 (736mm) barely fit in the arches without scrubbing.

I've sent off a query to RMS

Re: Thinking about oversized tyres on T31


That looks nice and mean now ... If one could phrase it that way.

I have the same tyres (and size) on the original steel rims. I like the black colour and I would consider upgrading our Exy with the same, as I think it would contrast well against our pearl white car with dark window tint. Although the boss has expressed how much she doesn't like the idea of black rims. Anyway ...

Can I ask how much just the rims set you back? When I looked to upgrade our rims with our tyres at the time our options were around $160. Not something I could justify t the time. The "raker", which I think over owners have used in a black powder I think would have suited well.

Re:


For NSW X-trailers

I have received official confirmation about the overlap between VSI09 Page 2 (15mm) and VSI06 Item 13 (7%). 7% overrides the old 15mm rule. Happy to send the response to anyone who would like a copy of it for legal purposes. Maybe Jalal can make a link to keep on the forum?

But there's a bit of a spanner which I'm clearing up - essentially if you modify the wheel/rim (going from 17" to 16"), then according to Item 14 of VSI06, your has to be covered by VSI09, meaning you're now 15mm above the 17" OD, not 7% (which is only for OEM wheels). I'm waiting to hear back from a technical person I've been dealing with at NSW RMS to see whether VSI09 applies if you drop to 16".

Re:


Ok. For those stepping down to 16" - as long as your new rim stays within the guidelines of VSI06 Item 14, then VSI06 Item 13 will apply.

NSW X-trail owners can increase their overall diameter by 7%
as long as
- OD is +/- 7%
- if changing rims, then width remains within 25mm of OEM
- load rating is the same or higher
- speed rating is the same or higher.

You're good to go.
So for those sticking with 17", its 225/65/17 and those going to 16" its 235/70/16, before you have to worry about scrubbing or ADR18 (speedo variance).

Please note the above only applies to NSW.

In ACT/NT/SA - VSB No.14 Section LS applies in full, and we're capped at 15mm as we're not 'designed for off-road use' (the discussion I had was that we lacked low range... but a previous model manual Forester with 1:1.2 transfer case was ok).

Thanks Twin,

Yeah id say they would look awesome on a white Xtrail. I paid $100 each for the rims.
 which i thought was pretty good.
