>50mm will never be signed off by DoT in WA

[Shakey]

I've just had an interesting chat with Dept of Transport here in WA and they have confirmed that even after submitting my application there is no way that a tyre diameter change of greater than 50mm will ever be approved/signed off/etc. not even with engineering and an LT2 lane change test.

Has anybody in WA ever actually bothered to get their larger tyres/etc. signed off/over the pits, and therefore how the hell did they do it?

All I wanted to do was put some 235/85/16 on my D2.

[nedflanders]

Everyone just ignores it :eek:

[agrojnr]

10% is allowed and engineering passable after that the WA boys don't care hence why most don't worry about it

I ran 235/85 on my D1 over there and never had a problem with the cops

Sorry to be the Fun Police!

The cops are the least of your problems, have a accident your truck is not roadworthy, now hear comes your real troubles!
I would hate to think how things would turn out if someone is killed.

Well seems one law for some ......

the WA cousins don't seem to bothered about chasing up an engineer for their vehicle mods

Couldn't agree more that's why I'm making sure mine's legal and signed off/etc.

That's why I said after 10% the WA boys don't care even if you prove its safe they just don't want anything to do with it hence why most have 2 sets of tyres

It's actually a 50mm diameter change, not 10%, which makes it even worse. :(

That ruling sounds about as inteligent as the P plate ruling in Vic regarding V8s.

VSI 8 states the same for Vic also. NCOP11 is the fedral standard this falls under, but nothing in there reflects the new VSI8 regarding the 50mm maximum tire size increase.

I would be approaching the roads authority in WA and asking them to provide in writting the laws that stop you getting the larger tires certified.

What was the largest factory tire size for the discos?

Tell your insurance, but don't bother with the permit

[Shakey]

Tell your insurance, but don't bother with the permit

Most insurance says 'any mods you let us know about and are legal' or something to similar effect so they have a get out clause to not pay out in an accident if your mods are to blame.

I know it's stupid, I'm prepared to pay a bit of cash to have my car engineered, I could legally get the height changed up to 100mm if I keep the tyre size within 50mm, I want to change by less than 75mm but have an 8mm larger diameter tyre than 58mm and the bods at DoT say no :(

Shakey,
Have you actually put a tape measure on the tyres.
doing the numbers ((235x0.85x2) + 16x25.4) = ???? is a joke because there are no two 235s the same dimension. I am sure that you could find a 235 that is only 48mm taller than an OEM tyre, just as you could find one that is 78mm taller than OEM.

The legislation AFAIK says "<50mm" it does not say "< 50 calculated from some company lettering on the side of the tyre mm".

I have four different flavour 235s with at least 30mm in OD between them.
"Small for size" are oldskool BFG AT, Hercules Terratrac, Dunlop Road Slippers.
"Large for size" are Bridgestone MT, MIchelin (7.5R16 thou) and

I am doing that, the problem I have is I can't find the diameter of the originals that Landrover fitted.

Am I right in thinking D2 came standard with Michelin Latitudes?
They are still available are they not?

My 2003 D2a came with Michelin XPC tyres. No longer available unfortunately.

Shakey, I have a partially worn XPC in the shed if you need an actual tyre measurement.

If you could let me know please that would be great!

The XPC in my shed is a bare tyre, not on a rim. The tyre has a convex shape across the tread and measures 730mm diameter at the centre of the tread, or about 715mm at the tread edges. It has about 5mm tread depth left, so you could add approx 10-15mm to the above diameters at full tread depth.

Have fun.

Original tyre size should be on the placard on the drivers door

That's just the ratio (I.e 235/70/16) and different manufacturers have slightly different diameters within that size.

[CJT]

Even though there is a variation in overall tyre diameter between manufacturers this is somewhat irrelevant.

If and when your vehicle is checked for complaince, the actual tyre diameter from the tyre manufacturer generally does not get used due to the variations, instead they use what the tyre standards book lists for a particular width and aspect tyre as listed on the vehicle tyre placard.

To legally come within the 50mm diameter increase from what I recall you are looking at 245/75 R16 or 265/70 R16 or any tyre that comes in under 788mm (31") overall diameter.

i went through the pits with 265/75/16s and nobody batted an eye lid :p hahahah in victoria mind you

Yeah, amusingly the pits people know F-all. I went to get my permit for mods the other day they said I didn't need one even though I had a letter from DoT saying I did!

that wasnt half of it, the woman didnt know where to look for the vin number and asked me to read it out then said stuff it to the engine number and asked me to read it off the RWC hahahahahaha fk they hire chimps at the RTA

[Shakey]

Their actual words were that's a rare car (it's a D2) and it doesn't look like a preying mantis so I wouldn't bother wasting your money mate.

[bmw535guy]

The Vic roads chick on the phone said i should not buy a car without a RWC as its against the law...............i pointed out to her regardless of what she says i can buy a car without a RWC.....old owner sends paperwork to vic roads and i get 28 days to get a RWC or the reg is cancelled.........she didnt like that but it is the LAW 100%.............funny how few know this. Kinda the same as its not mandatory to vote in australia UNLESS you enroll............and they cant touch you if you have not enrolled :p i know im 37.....never voted and never been fined !!!
