Off road tyres failed warrant of fitness

Have folk had their trucks warrant failed recently for off road tyres. Have a Ford Ranger with ARB lift and Mickey Thompson AT 285/75/16 tyres. Passed the warrant last year but not this year. Apparently tyres >5% bigger than stock require certification. Width for me not a problem but after research found that if the tyres are >25mm wider than original body panel, irrespective of flares added, then certification required as well. Seen a lot of trucks around the Tron that I assume are not warrantable. Do guys just swap out tyres for road tyres for the warrant or go the certification route? Certification cost me $725, cheaper than another set of tyres.

Way back when I had to get my surf certified because it came with wheels bigger than factory. Also had flared arches fitted. It had passed several warrants before I was made to certify it.

The rule used to be (may have changed) that the tread (not the sidewall buldge) must be inside the factory bodywork (factory flares count additional flares dont.) for a warrant.
Going by the amount of utes round here with half the tire outside the guards they either have freindly warrent guys or a factory set of wheels to put on come warrant time.

Thanks for the heads up. Looks like I'll be dragging out my old steel rims then for the safari and shoe them with 265's for warrent day.

I have factory size tyres but are MT on steel rims on my 2007 Pajero. The tread is borderline but acceptable according to my wof tester (i have been to my local garage and VTNZ) with the vehicle trim so i added custom flares to keep the dirt flick off at bay and keep the wof guys more happy. My factory mag AT tyres are all good/standard for compliance. Though i continue to pass a yearly WOF with the MT tyres, there are many others i see with obvious extended wheels on newer 4wd's that i suspect would not be covered in an accident let alone should pass a wof? Why risk it on some of those expensive Rangers etc? Each to there own.

I bought my 2016 Ranger with wider wheels and flares fitted, when i went for the first wof after 3 years was up it failed because of the wider wheels. I told them that is how i bought it new (from them) they paid for the cert.

Apparently a year earlier things had got a lot tougher with wofs, inspectors were losing their license for not following the book 100%

WoF regs have changed for tyres and wheels in the last 6mths or so.
Used to be only allowed a total wheel track width increase of 25mm before cert was required. Now you can go wider 25mm past factory guards so long as all tyre is covered by a flare.

The 5% max increase in wheel/tyre circumference has always need a rule.

Being the pertinent bit.

I get utes through all the time, covered in shit, cobwebby factory wheels, then see them a couple days later with the 33s back on (as do you probably). It's a time of test thing, not my problem anymore.

I sold my faithful old diesel-Courier, week before last, to buy a people-mover to address our needs. Bought a tidy 2nd-gen Honda Stream, with 17" factory-mags ( 205/55/17 ). Phoned to cancel ute insurance and have the Stream covered. All went well, then got a call back from the same person I'd dealt with. Lumley Insurance are the Underwriters for Westpac, apparently they arent happy about the Mags and claim they are off the Sports model of the same year. (which for some reason is 2k slower than std model) I have to get back to them, and dont know if I am even covered at this point. The mags are clearly labeled Honda. PN Honda have looked at the vehicle and confirmed that they were available upgrades from new, along with other upgrades that they pointed-out, were on my vehicle. Part of the insurance process/disclosures was about Mags, and/or wheel modifications (and exhaust). They didnt want a bar of 'aftermarket' ones, ie, wouldnt cover it, suggesting that if you fitted them after the fact, then made a claim, it wouldnt be covered. WTF! where has commonsense gone ? I would bet, you wouldnt be covered by Insurance with mud-tyres.

put different tires on to get the warrant and just take it somewhere else next time

pricks like that piss me off

how much safer will you be after the certification?

It's all about insurance cover - claim on an accident with tyres not certified for your type of vehicle or agreed with on your insurance, what a waste of premiums. All my mods such a snorkel, 2" lift, MT tyres - i took photos, provided details and sent to my insurance - state. All covered. Keep it simple and up front for peace of mind.

‘Cool’? Nah…not in my opinion.

And likely noisy-as on tar seal.

Lots of rules are being enforced as of late , most of them are just a crock of shit!

looks almost like a rim without a tyre

I nearly failed my WOF a couple of weeks ago, for my lightbar.

Not because of where it was mounted. Not for how it was connected (separately switched from headlights).

But because it had been wired in using the old fog light circuit and switch, and due to the switch having the fog light symbol on it, he said nzta have said it must fully comply with foglight specs, and are pushing hard on tiny things like that atm. Simply due to the tiny picture on the switch..

He was a friendly chap and offered to let me disconnect it, but I thought for a moment and had a better idea. I borrowed his razor blade and scraped the foglight icon off the switch for a more permanent fix.

Think he was quite amused by that solution. Got my WOF, anyway.

Jesus Christ what a bunch of fucking jobsworths these NZTA dimwits are turning out to be

They are just the latest bunch of people running scared of liability.

ChCh earthquakes got the civil engineers in a pickle

White Island got the tourism and helicopter companies in a pickle

Now NZTA and the certification agencies are running scared: note the dramas with crawl throughs on horse trucks etc etc.
Oh....and fog light symbols:pacman::pacman::pacman:

That AVI should be shot!
Simply wrong.
A switch with a decal on it isn't a reason to fail.
Its performance or the way its wired in is.
The regs are very plain and simple in the VIRM.
How some AVIs interpret them is a real mindf**k.
They need to be dropped. You need to contacting NZTA about it, and they will get them reviewed by the inspector. Thats the only way that these twats will learn and get dropped

Quite often I notice tyres that have their rims so far offset its ridiculous. It can be quite dangerous as all the vehicles bits and pieces are not designed for the stresses that offset rims can and will generate.

Had a new set of tyres fitted to the prado recently and apparently 7% over factory sizing. Had to fit narrow flares as they were just proud of the body work as well. Passed WoF but might have to look at certing. Supposedly 2” lifts are ok unless they’re coils? Leaf and wishbone ok.

Spoke at some length to the certification guy. If you fail warrant for any one thing that then needs certification all mods then need to be certified as well. My ARB coils were checked even though were OK for a warrant.

Not so sure what Snowgrass means about 2" lift on coils. My Pajero is factory coils with 2" lift. No cert required according to legislation & wof dealers including insurance (they quote the same reference). Don't confuse people!

Does that sound right?

Or air bag suspension ;)

Yes. Any airbag added needs cert now.

Good to know. Was going off what my WoF guy mentioned as the Prado has a 2” lift on coils as well so he mentioned that along with the oversized tyres. Always thought 2” or under was fine.

Any sized lift is ok AS LONG as all the factory mounting points are unmodified. They actually don't have a listed max limit.
If the suspension is all bolt-in and uses factory unmodified mountings, they can't fail it.

Here's the WoF VIRM we as AVIs have to follow.
