An addendum to my previous post (thread 87769) on fitting BFG 265/17R/17 AT/KO tyres to my 120 series Prado GX T/D 2003 model instead of the "Cheese Cutter" 225/70R/17s that were already on. After contacting the mob who installed my 2" lift kit (Bilstein shockers, Lovells springs & Polyairs) they directed me to call an engineer they know. He told me if I wanted to continue to use the tyres, I needed a calibrator installed ($400 quoted from a 4WD place) to make the speedo show the correct speed. Then I need a sticker in the lower R/H of the windscreen to reflect the tyre speed (lowered) I then need Mud Flap Extensions, as there must be not less than 300mm between their lower edge and the road. Finally, I'd need an Engineering Certificate ($300) to make the whole shebang legal. And yes, your Insurance company won't insure you unless you do all these things! My tyre mob, when contacted by phone initially said to put a new tyre placard in the door. I said it wouldn't be legal, and the bloke said yes, it wouldn't. I said I wouldn't do that and they wanted to see the receipt for the tyres. I went there and showed them and they asked when I had the lift done, which was before the new tyres were fitted. They said the boss reckons it's legal, no prob. What to do? I can 1. Sell the tyres/rims and go back to the cheese cutters, or 2. Remove the tyres from the wider rims and sell them, then fit proper profile tyres to the rims, or 3. Spend all that money to make what's there legal (if the Engineer says they are) or 4. Continue to drive the way they are until they wear out enough and hope I don't get in trouble or have an ackydent! I just dunno...

G'day Lozza' You are in a bit of a dilemma there mate.
To drive with full insurance coverage or not to drive with full insurance coverage.
So I assume from whet you have said that the 2" lift is legal then.
You have obviously been diligent enough to go to the correct sources & find out the facts. Good on you for sharing it with us.

Lots of people (and I mean lots!!!) are happy driving around with a 2" lift and slightly bigger tyres even though it is illegal.

AFAIK the suspension lift is legal but the tyres are not. Under VSI09 (if you're in NSW at least) tyres cannot be more then 15mm bigger in diamter to the tyre placard without engineering. i think it's similar in QLD.

A tyre place I had work done (alignment etc) said a 2" increase in size was legal... so I won't be going back there again.

I vote option 2 if you don't need the increased tyre clearance.

Hi Lozza,
What a delemia.
I have a GXL 120 series & also looked into this when I 1st got the vehicle due to lease requirements, & found the same case scenario, in the end to stay within the letter of the law in Vic I fitted Bilstein shockers, Lovells springs 50mm lift, & BFG 275x65x17 tyres these are slightly wider & taller but with 2mm of the legal limit, maybe if your tyres are so new you can trade them at the place of purchase & just pay a gap.

Speedo wise it is 100 @ 100kph verified against the GPS reading now before it was reading faster then actual speed.
I also carry the Vic regulation printed in the glove box just incase anyone distupts the point.

cheers Simon.

Hi Lozza.

It all boils down to your appetite for risk, mate.

On one hand, there are lots of 120 series Prados set up just like yours running around NSW without engineering certificates. The 265/70 R17 is a popular tyre.

On the other hand, this set-up does not comply with NSW regulations, leading to possible legal and insurance issues.

FWIW, and as you would have found on Pradopoint where you also posted this issue, there has not been a reported case of an owner of a vehicle set up like yours having problems with the law or an insurance company. But you wouldn't want to be the first!

Whatever you choose to do will be cheaper than moving to Victoria (or SA, I think) where 265/70 R17 tyres on a 120 series Prado are legal.

Good luck!

Come any closer and I'll rip your throat out!

Remember though, Insurance companies will try and do everything it can out of paying on a claim, eg if you skidded into someone and the insurance company inspected your tyres, found they are over-size and hence you had reduced stopping ability, I'm sure they'll cancel on your policy.

As others have said and from what I've read it has never happened but I wouldn't like to be the first.

Considering what's been happening in NSW in recent months with the tooing and frow'ing of legislation I'm not sure how long I would want over sized tyres.

No people think insurance companies will try and do anything to not pay a claim.

I would love every 4x4 to go over a weigh bridge and see if they are legal.
