Does anyone know how much it costs to get an engineers certificate if you use larger size tyres. VicRoads says only 15mm higher in Dia is ok over the largest size tyre used on any model of vehicle you have.
I have a 2005 model hilux. The largest sized tyres used on any model is 255/70 R15 (around 740mm). Even with the 15mm I still can’t legally run 31/10.5 r15 tyres with an engineers certificate.
Anyone have any contact details for someone in
melbourne?

Ring a bloke called Andrew Enkelman 1/5 Breaside Drive Breaside Vic ph 95803024 I know he does trucks but may know someone who does that sort of thing. Vic Roads has a list called the VASS signatory list. This has a list of engineers that are approved to do such reports and I think it is on the internet. If you ask at a VicRoads office they should give you a copy.

Depending on the engineer, around $300-700...
People are having issues finding one that will do bigger tires now.
Search the
forum for Kevin Williams. He used to be THE man to see, did my GQ with 6in lift, body lift, bigger tires all in 1 go, but he wont do squat anymore. Dont think he does 4wds at all from what I read on other forums

I was at Vic roads yesterday checking into changeing seating capacity of my cruiser
they gave me a 5 page list of certified engineers across Victoria
Hope this helps, it was going to cost $200 for certification for seating.

I upgraded my 265/70R16 on the prado to a 75 profile and raised springs. Half the tyre diameter increase you are planning but I still went through the hoops and process (rather rigourously too).
I couldn't find an engineer around where I live who cared. The
feedback I got was just to make sure you can still get RWC and insurance.
With mine, RACV did not care about the tyre height, nor the lift of <50mm. They do care about extra width, however I can't remember the detail as it didn't apply to me. The RWC joint down the road also didn't care about the mods either. So, I just put them on and advised insurance. (the fiasco resulting from getting
the springs done by Bridgestone at the same time is anther story!!)
But as I said, mine was 1" diameter more, your is 2". Could be different.
ps. are they going to fit?

Tonester,
Your tyres dont rub on the inner guards at all?
31/10.5 r15 are on at the moment but with large offset rims which rub on full lock, changing to a navara offest to see what that does.

Hi Hound.
Its a 2000 Prado btw. The raised springs was meant to prevent rub, and appears to to a degree. Does rub only a little under compression at near full lock. Full alignment done after the springs/tyres went it, nothing else. I figure it'll grove out the guard over time(!).

Did you get it engineered in the end?

Truckster, nope didn't. VicRoads were the only ones who said it was needed, and their own recommended engineers said don't not required just get a RWC. Rather frustrating the whole thing, from looking can hardly tell anything has been done to it. Try and do the right thing and all.

Out if interest, the ridiculous 15mm thing was dropped out of the ADRs on January 1st 2005. ADR 24 was replaced by ??ADR 40.
The States have their own rules, but maybe engineers are losing interest because if this change.
Cheers

Hmmm. From Dotars Website
ADR24 is retired.
ADR40 is not used.
So wonder what that all means. Does it mean you can run whatever height you want?
Hmmmmmmmm I wonder.

Sorry Glenno, I just got off my butt and looked it up properly -
ADR 42/04 replaced ADRs 7,15,16 and 24.
ADR42/04 has no specific reference to tyre diameter.
AFAIK, the State laws take precedence, and confusion reigns supreme!!!!
Cheers

I legally run 30*9.5R15's on my SR5 Hilux. They look too small. the 31*10.5R15 matches the size of the truck "looks" wise.
The 30*9.5 is within 15mm.
Cheers,
Glenno.
