ADR's allow 1.3 x the size on the tyre placard

ie:: 16x7 you can go up to 20x9

That's odd... I thought it was only 2" bigger than standard.

[bozodos]

8.5 is kinda skinny for an 18 inch wheel, have you thought about 18x10?

What state are you in? The laws are slightly different for each state.

Yeah ^^^ Just ring your states transport and they will let you know (providing the person you speak to actually knows what they aretalking about)

the 1.3x rule applies to tyre width, not wheel size.

there are not rules as far as rim diameter goes, provided that the outside diamater isn't more than 15mm smaller or larger than the standard diameter of the wheel and tyre, and the tyres must have the same load rating (or higher)

also that link to the NSW RTA states that you can only go a rim 26mm wider than the widest rim on the tyre placard without needing to get it signed off on by a signatory. and the widest you can go is only 2" wider. so that means you could only go a 8.5" wide rim on a 33 gts-t, etc.

qld however only uses the 1.3x rule for tyres (plus load ratings) and the +15mm diamter rule. no rim width rule.

seriously who gets defected for rims these days? the last time ive ever heard of sum1 being defected for rims was probly 4-5 years ago. police are more concered bout engine mods and epa guidlines than the size of your wheels.

[mad082]

well if you stick with 18 x 8.5 you should be safe

Wheel cannot be more than 26mm wider than the widest on the tyre placard. Offset cannot be greater than 12mm lower than the lowest offset for any wheel on the tyre placard. Wheels cannot be narrower than the narrowest wheel on the placard. Offset cannot be higher than the highest stock offset.

Tyre diameter cannot be more than 15mm outside the diameter of the stock tyre (greater or less than). N.B. the wheel diameter is "free" as long as you can find a tyre that fits within this bound, regardless of what a cop tells you.

However, since you want to avoid a yellow, a lot of cops mistakenly believe that you can only go up 2" in diameter so for safety's sake I'd recommend that.

It's all on the RTA web site, as [200] said.

QLD Standard : The rim diameter may be varied from the standard size but the overall diameter of the tyre must not vary by more than +15mm or -26mm.
