Thread: 33" on D2 does anyone have them engineered ?

Aww, c'mon, those blokes wouldn't do that would they?

4.2.11 Off-Road and Goods Vehicle Wheel Track
The wheel track of off-road four wheel drive vehicles and goods vehicles (MC, NA, NB ADR category) must not be increased by more than 50mm beyond the maximum specified by the vehicle manufacturer for the particular model.

So this engineer is a bit suspect.

Yeah, that's what I was saying in post # 19:

I note that previously you said that the engineer would only allow a 25mm track increase. From my reading of National Code of Practice VSB 14 ( Vehicle Standards Bulletin 14 (VSB 14) - have you checked if NSW have adopted the NCOP? I believe most if not all states have now), it is 25mm increase each side for a total of 50mm increase.

It's the first that I have heard of warning lables being required.



I thought you said that NSW has not signed up to NCOP though? VSB is a NCOP document, so if NSW has not signed onto NCOP, then you are looking in the wrong document.

Yeah, sorry, meant to include your comments in my post as well

My bad getting confused here myself, in NSW applies
http://www.rms.nsw.gov.au/registrati...vsi09_rev4.pdf

An important requirement for all replacement wheels is that the wheel track must not be increased by more than
25mm beyond the maximum specified by the vehicle manufacturer for that vehicle.
Where non original axle or suspension components are fitted, the offset of the wheel in relation to the axle or stub
axle assembly used shall not be increased by more than 12.5mm each side of the vehicle based on the specifications
of the axle components used. If an axle assembly is shortened then the track width limit is taken as the axle
manufacturers original track dimension, less the amount the assembly has been narrowed, plus 25mm.

It's the first that I have heard of warning lables being required.

VSI 09 applies in NSW

If the replacement tyres fitted, including winter tread tyres (commonly called “mud and snow” tyres) and retreaded tyres, have a speed rating less than that shown on the vehicle’s tyre placard, a warning label must
be affixed to the vehicle (usually by the tyre dealer) which states:

WARNING
This vehicle is fitted
with tyres which
have a lower speed
rating than that
specified on the tyre
placard.

RTA VSI No. 9
The label must be at least 40mm x 40mm
in size, made of durable material, with not
less than 2mm high black lettering on an
orange coloured background.

I thought you said that NSW has not signed up to NCOP though? VSB is a NCOP document, so if NSW has not signed onto NCOP, then you are looking in the wrong document.

sorry correct myself just started looking in to this yesterday and it is a bit confusing VSI 09 applies in NSW

Okay I'm getting the ball rolling I've booked my speedo correction for next Monday (between $350 and $450 at MIS) and a weekend in Orange with Treeve from Kernow Engineering Pty Ltd for the lane changing manoeuvre and brake test for the second and third of November.

Also currently sourcing 6 x standard LR alloys

Whats the plan of attack for the speedo correction? Previously I used a Truespeed. It was spot on. I used a GPS to tune it and once tuned it stayed true.

I would highly recommend this and it's a lot cheaper than $350.00!!!

I now have 4.11 diff gears fitted which have brought the speedometer back to standard without the need of the TrueSpeed (and improved the acceleration).

What are you doing with 6 wheels?

Baz.

Some, if not most, of the D2 alloys are 16X8 too. I ran 33" tires on my 2003, but the rules over here aren't as strict about modifications.

The tires I ran were 255/85R16, which fit nicely in the stock wheel well and custom flares were not needed, the stock flares covered the tires. I also only needed two to three inches of lift.

I do wonder how the lane changing and brake test mentioned will turn out. Being that the vehicle is designed to tow 7000 lbs, I wonder if the engineers would allow larger tires with reduced or removed towing capacity.
