Engineers Certification??
It not for a 4WD Sorry, or for me.
But my Brother (Still at Uni) has just replaced the standard Rim’s on his 1997 Fairmont with 17*8 inch BA XR6 ones on 235/45R17 the tyres are not the problem but the Rim’s we have just discovered are illegal.
The widest factory option on this model is 7inch and there is some ridicules law that say’s, if the widest factory optional rim is 7-inch then you cannot go above that, but if it had 8-inch rims standard then you can go to like a 10-inch one with no issues.
So I said no worry’s I will just take them to the boy’s in the machine
shop at work and we will mill off the 17*8 and restamp them as a 17*7-inch rim. Or just go to ford and get a new tyre placard for the car. He was not to keen on those ideas.
So how much would it cost to get the Rim’s certified by a engineer and what is involved?. Would there be much testing/ cost involved just to certify Rim’s as the rest of the car is legal. If told him probably around $400,
Personally I think this law is Compleat bleep as he can legally fit the 235tyres but can’t put on the best fitting rim size for the tyre. It also appears that under the new National law’s that are being voted on the rims would be legal.

It all depends on what is involved.
Eg. If you want to go over tyre max tyre specs regarding rolling diameter you immediately bring into question things like Brakes, Bearings, etc etc.
When proposing an increase in any of the OEM engineered specs you are potentially looking at a 'nightmare waiting to happen'.
I have just spent a heap of time, effort and money (not including the engineers costs) to raise the GVM of a Troopy. The Engineer was the cheapest part.
I would respectfully suggest that you (1) find out what is required/involved in increasing the OEM specs re rims and then (2) contact an accr4dited engineer re price to engineer same.
NOTE:
You didn't say what state you are in, however in Victoria there is a List of accredited VASS engineers held/issued by VICROADS, and you are wasting your money and time if you have your vehicle engineered by anyone that is not on that approved list, as VICROADS will not accept any engineer report/certificate other than a VASS one.

Im in WA.
The rolling diameter of the tyre is the same as stock or 2% bigger at the most; the tyres are with in limit’s width wise as
well.
The only issue is with the rim’s being 8-Inch wide and the largest optional rim available on this Car was 7-inch this makes putting a 8-inch rim on illegal in WA. I find it ridicules because if it came out standard with an 8-inch rim he could put 10-inch wide one’s on and still be legal. But it is illegal to go from a 7 to an 8?? How can that make sense?
And>
Thanks I will pass that on.

I posted a detailed reply to post 27992 a half hour ago which you were a contributor to and therefore should have been on the reply post list.
Its about tyres and rim oversizing here in Victoria which I was led to believe was the norm for the rest of the country.
Have a look at it and it might give you a an idea or two.
The 'wording' of the appropriate regs has to be carefully analysed , not saying you haven't already done that, because I thought
mine were illegal at one stage until I read it about 10 times then consulted the subject engineer.

Thanks for that, it appears it is all
well and legal in Vic, I will have to run over the WA law’s a few times so we get it sorted.
Cheers.

sorry mate , you'll have to move over to vic :-))))
rims can be a plus one or plus 2 fitment, ie 15 to 17 inch and a 25mm increase in width to the outboard track.
and if you do up an older car and fit a ford 9 inch diff you can legally fit 10 inch wide rear rims as the diff has been approved for these bearing loads.
I can legally fit 20 x 7 rims to our new astra, how ridiculous is that !!!
