Do You Get More Attention With Your Wider Wheels? 9-10 Inch

[joeyjoejoejuniorshabadoo]

what scathing is saying is that different tyres have different recommendations for rim width,

ie... say a 235/40/18 ku36 might be recommended for a 9.5 max width, where as a 235/40/18 re001 might have a 10" max width

these are certainly not accurate details, merely fairytale examples to illustrate scathing's point

as wheeldeal has said, ADR's overrule this anyway so its best to go by that if legality is your game....

not that any tyre is legal on a 10" rim on a skyline anyway...

[scathing]

perhaps comprehension is not a strength of yours.

My comprehension is only as good as the data given to me. If people have no idea what they're talking about, it's really hard for other people to understand what they actually mean.

my question purely related to a 10" rim and what is the suitable tyre for this

So why did you initally ask what was a legal tyre (try and actually read what I quoted you saying if you can't even remember it yourself) rather than a suitable tyre like you are now? My response also covered the legality of said tyre. I said the rim was irrelevant. You're the one that keeps harping on about the rim.

My comprehension is based on you initially asking for legality. If that's not what you meant, then why don't you try and actually say what you mean first go? Most of us aren't mind readers, and some of us give people the benefit of the doubt and assume they're not idiots that need everything they type double checked.

If my assumption about you was wrong, I apologise for giving you too much credit. Undeserved optimism in others is a flaw of mine.

i didnt ask about the legality of the rim on the car.

And my response didn't mention the legality of the rim either. I mention the rim in passing by saying its size is not particularly relevant to your question. Read them again.

If you're going to accuse people of comprehension issues, it'd be in your best interest to make sure you're not in a greenhouse before picking up those rocks.

Since you initially asked what a legal tyre is, having just had a read of the VicRoads Vehicle Standards Information Guide to Modifications for Motor Vehicles there's no rule on how much wider you can go.

The VSI with respect to tyres states that:

1. the tyre can't touch anything (bar the wheel, obviously) at any point in time and it must be inside the guard when the wheel is straight ahead

2. the tyre can't be more than 15mm greater in diameter than the biggest tyre available for that series of car

3. the tyre can't be more than 15mm smaller in diameter than the smallest tyre available for that series of car

Note these restrictions make no reference to the wheels, which is what I originally said.

The VSI does make mention that the wheels and tyres need to comply with the "Tyre and Rim Association of Australia's Standards Manual", which does contain "Recommended tyre fitments and allowable variations" but I can't find a copy online to see what the rules on stretching or ballooning tyres are, or if there's a maximum width limit over stock (like there is in NSW's modification rules).

Even ignoring stretched wheels, if the tyre is actually suitable for the wheel but it doesn't come in a profile that keeps it within the "15mm variation" rule above, then that tyre still not legal for your car.

Lets say you have a R33 GTS-t, which runs a 205/60 R16 on a 16x6.5 wheel. If you went to a 17x7.5" wheel and ran a 225/45 R17 Falken FK452 (so perfectly legal rims for the car, and tyres that are a manufacturer recommended fit for a wheel that size) then this would still be illegal as your new tyre's diameter is 18mm less than the stock tyre.

The rim didn't matter to the legality of the tyre. Only the OEM tyre size. Which is what I said.

regardless of the car the tyre must be within the guidlines for that size rim unless im wrong?

For safety and warranty purposes definitely so.

Legally I haven't seen any law against stretching tyres (although I would love to get my hands on the Rim and Tyres Standards Manual). There's nothing specific in Vicroads' VSI's for wheel and tyre changes regarding that anyway.

As for suitability of a tyre for a certain rim (as you've changed your question to after my initial response), as I originally said:

Tyre manufacturers have recommendations for what sized wheels you should fit certain width tyres onto, but these vary from tyre to tyre.

There's no absolute rule that a width tyre is automatically "suitable" for a b width rim.

Some manufacturers publish recommended wheel sizes, but quite a few do not (especially on Australian web sites). In case I can't find any on a specific tyre manufacturer's local or international sites, I tend to use Falken USA's web site as their tables are quite in-depth. Here's the fitment guide for the Falken FK452:

For an example of how it can vary, here's the fitment guide for Dunlop DZ03Gs.

http://www.stuckey.com.au/tyres_details.aspx?TyreName=DZ03G

If you look at the 235/45 R17, the DZ03Gs are suitable for a 7.5-9.5" wide rims whereas the FK452s are only suitable for 7.0-8.5" rims.

The tyre construction will play a big part in its suitable rim widths. Obviously no tyre manufacturer is going to recommend stretching a 195 width tyre over an 11" rim, no matter who makes it, but in less extreme cases the line is not so clear cut.

not that any tyre is legal on a 10" rim on a skyline anyway...

what about a 33/34 gtr with 9" wide factory rims

scathing stop wasting your time multiple others have understood and answered my question quite easily so you can give up now you have more then proven the point that you can use google search and pretend to know what your talking about it seems you are just looking for attention. either way your contribution is no help at all

and for your information running stretched tyres is illegal.

[nisskid]

hmmm....what he said....

but if ur overly worried about police u shouldnt be driving a skyline in the first place.

[nisskid]

btw legality legschmality, drive what u want, get defected, get cleared, drive more.

f**king playing the game, ull come away with a red sphincter either way.

[scathing]

either way your contribution is no help at all

Nice "graceful exit" for your lack of comeback.

The links I provided were to illustrate what I was saying with concrete examples, or proof from the relevant bodies. I didn't realise backing up what you say with evidence was "no contribution" these days. Especially when I'm providing you with general-case information that's applicable no matter what car you're talking about, in case comprehension of the principles behind it actually mattered to you.

But I will take your advice and give up trying to explain how the rules work. Some people can't be helped to help themselves, and just want to be spoon-fed.
