Outer Limits 4x4 Board

last time i got defected the 35 radial claws on 10's wern't the problem - the lack of mud flaps and flare rubber was. it sucked cause i honestlyy was on my way to work to fit it - it was in the back of my cab!


hoons a dropped panhard will fix that bump steer some what. like a 3" lift and standard panhard would compare to a 5" lift and a dropped pahard in terms of bump steer

double post

any one got pics and stuff for dropping the panhard?

AFAIK - Speed rated radials > 35" are:
MT/R 37 & 40"
BFG Krawler 37" & 40"
BFG M/T 37 (on 17" rim)
to name a few.....

I believe that it truly should be physically possible - just bloody difficult to get those tyred engineered......There are plenty of other vehicles with bigger tyres - trucks busses etc.....there would be a loop hole there somewhere surely

mate says hummers come with 37's stock?

That they do GOOD YEAR wrangler road pattern

Yup sure did.
What about okas - they look like they have pretty big meats?
And well mogs

But mogs and oka's would be registared as trucks. So probably reading a different set of rules. But I have seen an oka on 35"BFG muddies.


Just on these comments about braking efficency, strenght of hubs, spindels etc. This would be a plus if you could change axles to something that is designed to take a big tyre ie mogs/volvo portal axles with with either drum or disk. As they are out of 10+tonne trucks.
But could you also say that if the axles out of a patrol come from there truck range (like the rest of the running gear). Could its tyre size be used?

That was sorta my badly worded point....

Hey Bru,

Siggi the 80 series has had some work done to it. In order for it to have it's little blue plate and that sticker for the window, Siggi went through some extensive testing over a fair period of time. It's approved with 44's. it went through brake, lane change, high speed manouvreing and a few others. It has active body suspension which helps a lot. It handles and pulls up better than a standard 80, IMO.
It helps that it has been registered and had been approved long before they really started cracking down. It started off with Southern Plates and was transferred to Qld Rego for a while. You'll also notice that it is no longer Qld plated.
If you want to chat to the owner, let me know. He is a lot more knowledgable on what was required. All in all it was more of the owners persistance (and a desire to have it on the road at any cost) that kept Siggi on the road.

In response to the tyres, all Mickey Thompson Bias tyres (except for the 46" Claws) are speed and load rated for Australian Roads. They are deemed by the manufacturer as suitable for road use, so structurally and technically speaking, there is absolutely no problem with these tyres being used as every day drivers.
It's more the size issue. With increased diameters, comes more strain on the vehicle components, longer braking distances, higher centre of gravity and the like. In order for the tyres to ever be approved by DOT, you are going to have to have all the documentation to prove that everything that affects the safety of the vehicle has not been altered by the mods.. if anything you will have to be able to prove that the vehicle is now safer than it was standard. To do this you will have to get test results from a DOT recognised facility.

Good luck Bru.
Cheers,
Ryano

I know it's not QLD but my cousin in SA had his Hilux reg'd as a light truck, would this be a way around it
As I'd say that there would be different rulings for a light truck.

Mere

another issue is RECOMMENDED RIM WIDTH. That being you cant run more than 8's on 4b. Why is that? What difference would it honestly make?

shedguy tried gettin his Troopy engineered with 15x10's, but got nowhere. he was runnin 36x13.5 I think swampers.

I don't know this to be fact, but I think one thing the QLD rules don't have is the 8" rim width limit?

Only track increase restrictions. NJ SWB would know more.

When it was first introduced in NSW it didn't apply in Qld. But I haven't checked lately, so I don't know if they've slipped it in.

as my old mans car hast to go through the same tests, i might wait till his is completed and we can do them together which should save a lot of $$$. i don't mind spending a few grand as long is its possible and 100% legal ie accident proof!

i was thinking of getting the 38" radial claws on 8's to get approved
we will see

thanks fellas.

nice work, keep it up, i would be more interested in finding out more details of what the tests and stuff they require you to pass will be

different requirements in QLD to Vic so what he needs and does may not be relevant in Victoria

Your Old Mans car is an Individually Constructed vehicle right? It has no Compliance plate or vin Number currently? It hasnt been built on an existing Chassie has it?

Your Patrol allready has a Compliance plate and Vin Number. So it comes under a totaly different set of rules.

Gas Axe!

There is a way to get the vehicle a new vin. In the wrecking bussines all vehicle that are under 15yrs old once they have been pulled apart they are to be classed as a statutory write-off. There vin is then no longer usable. This may help you get your vehicle its individual construction as it seem to have been substantialy modified.If you have got photo's of it pulled apart and brackets being welded onto it that may help aswell.
Just a different approach to look at even if it is over 15 yr old it could be still possible.

yes

correct

no we are building it from scratch.

yes but the tests are the same. eg lane swerve at 110km/ph etc. all my point was is the engineer only has to set up the tests once.

cheers

Ok we looked at building Tube Buggies to suit rego on a Range Rover Chassie. But because it allready had a Vin Number it had to meet all requirments for that particular vehicle. Which also ment we could only run the same tyre/rim combination as set by the original manufacturer.

I beleive if you can get 38" Tyres on a Patrol absolutly without a doubt legal in QLD this will be a first.

Hey Ryano i was under the impresion that the 80 was transfered back out of QLD rego due to the constant hassel QLD transport was giving it.

Going back to when the 80 was first transfered to QLD rego it was possible to get away with any mod that had been done to a vehicle and had been approved and registered in another state for more than 12 months. I knew guys that were running around with 308s in LJ toranas with QLD rego on them more than 10 years ago when this was totaly Illigal in QLD. All because they first registered and engineered these vehicles in NSW for more than 12 months.

This loop hole no longer works.

I don't have any facts to add. But I will say good luck. And keep us all informed how you went.

But what still hasn't been explained to me fully yet is how can DOT knock back a car when it has engineering approval already. I thought that was why you got engineers to approve your car so it could get rego. And if the engineer has approval from DOT and DOT can still knock the car back. Why bother spending the $$$$ going to a engineer to begin with?

On the last question, if the DOT is anything like getting saftey approval on a product in Australia, and it probably is simiar, then the lab (or engineer) provides a report based on the standards/rules (and is there interpretaion)
the goverment, being the regulators, or in this case the DOT, then approves that report and issues a certificate, a car that was enginnerred in another state or a while ago, was done so to rules/standards set then, so requirements may have changed or be different, so basicly

The regulator or DOT have the last say and can accept or reject any report issued, so a enginners report is worth nothing unless the DOT/Regulator is willing to accept it

For example, (with the saftey of electrical products), insulated pins on plugs became mandatory recently for all current products for sale and all products coming for sale soon. However the regulators have given a extension to those who apply for approx 12months

However, the opposite is also applicable, sometimes the reguators may request more to be done (or harsher regulations) than whats allowed by the standards that apply (or even in some cases require tests of standards that arnt even adopted by australia)

Also regulators, and I assume the DOT, have the right to withdraw a certificate for any reason

So i take it that loop hole explained by ruff of getting something approved in NSW and transferring to QLD doesn't work anymore?

Correct

that i wouldnt know
