    Firstly, who gives a toss the ramifications of what Holden called their wheels, that Ron's referring to.....If it's an issue, let the owner of the trademark take it up with Holden..

    2ndly...20" wheels will have a slightly harsher ride, due to the lack of sidewall give, that a 20" tyre will provide.

    A 20" tyre will be slightly more expensive, because the demand isn't as great for these, as a 18" tyre has....From memory, 19" tyres are about the same price as the 20", due to demand.

    I understand the frustration of having staggered rims fitted and how little you can do.....My suggestion would be, try and find a 18" decent rim that you like, that can be fitted front and rear, so you are able to rotate them and provide a comfortable ride....Maybe do some trade with the staggered rims you have, or just buy outright....

    As for what was fitted from the factory....Maybe in 30 years, someone will want the car "factory original", when purchasing, but honestly these days, not having the original wheels on the car when selling/purchasing, only appeals to the minority of car buyers....

    Yep, agreed that companies protect their brand or trademark. But such desirs can't cross into different industry segments. Again, Corn flakes are a branded and most certainly trademark protected breakfast cerea but that doesn't mean that a company selling flakes used to embed in epoxy floor coatings can't call their flakes corn flakes. So we'll just have to agree to disagree.
    Ron's rims are genuine OEM and not some aftermarket addition. However, I take your point that having what was factory installed (optioned) would be more desirable in future.

    I am keen to change the rims as the price for tyres between 19's and 20's is negligible, I will be able to rotate tyres and it's what the car left the factory with.

    I did some check load rating difference and it's not an issue for me.
    95 load rating gives me 690kg per tyre or 2700kg combined which i would never even come close to anyway.

    My rear tyres are already 35 (275/35/19) so I dont expect significant difference in ride quality.

    I may have badly worded it as I wasn't talking about Ron's car having aftermarket rims, I was talking in general that a seller who has a nice set of rims will often still be asked about the originals.



    Touchy, just members bantering back and forth about a comment in a post.



    Maybe I just buy then sell too many cars I've modified but I've been asked the question many, many times.

    It may not matter with a run of the mill family cruiser but try and sell a HSV new or old without it's OEM rims and see the response you'll get.

    The same goes for other makes and models that have more than just an A to B appeal.

    In NSW, at least, the wheel diameter is irrelevant & what matters is the overall rolling-diameter of the tyre plus the width of the wheel. Even if the 20’s hadn’t been an option, the fact that HSV’s are considered the same chassis means that whatever maximum widths they ran is considered the max ‘standard’ width, then you’re allowed an extra inch of rim width (assuming no rubbing nor offset change nor do the wheels or tyres protrude from under the guards).

    Probably just bad repair. On one wheel only

    From a strict compliance perspective, anything that is not defined within the RVD for a specific ‘model variant’ is considered a modification.

    In Ron’s case, his SS Black only specified standard 18x8” and optional 20x8.5” wheel/tyre. So using 19” OEM wheels from another model, which are equal in offset, track and running diameter, are an uneventful mod but a mod nevertheless. I believe the max width he can go to is 9.5”...

    To date, a slack approach has been taken by the rego authorities as to ‘model’ vs ‘model variant’. And VSI 6, 9 & 14 all play a part in what’s allowed when modifying a vehicle. But these VSI’s are only a simplified interpretation of the ADRs and a manufacturers compliance of their vehicle model variants (model variants being the operative word).

    The driver behind this changing view is ABS/ESC. Such is going to have an impact on the current rego authorities view of the rules and what’s allowed. They’ll likely tighten up their interpretation for vehicle modifications much as they did with 4x4 lift issue (the **** storm that became). That’s because when the manufacturer compliance’s a vehicle, they specify lots of certification test data with model variant specific ABS/ESC calibration data (which is not publicly available). It’s becoming a pain and will force more mods to be engineered.

    So, sadly, the wheel/tyre specification in the RVD for a given model variant is the critical and relevant starting point. An Evoke, as an example, the wheel/tyre combo that is specified in that RVD for that variant is considered the starting point, what wheel/tyre combo a HSV has is not so relevant.

    The guide talks about 12.5mm variation max per side...

    From my own research, the difference of ride quality between 19" & 20" is barley noticeable. However 18" to 19" is a more noticeable change in ride quality.
    Aside from that there are other considerations such as range of tyre choices/availability/cost and risk of pothole damage. I would love to have 20"s on mine but my more conservative and practical side says tells me to stick with 19's as they still look great.

    Rim/wheel combos are uniform across Australia....ie, providing the rolling radius is the same as per factory, the load/speed ratings are equal or greater than the factory issue and there is no rubbing of body panels, or fouling of suspension components, they can be fitted.

    This is 1 area that is uniform across the board in Australia, when it comes to upgrading

    Simple fact is, upgrades, providing they meet the above mentioned parametres I have listed, is an accepted upgrade, Australia wide. It also doesn't matter what model variant the car came from the factory as...The upgrades are permitted, without any fear of repercussions from an Australian Rego authority....

    As a tyre fitter, I must be aware of these upgrades, because if an interstate car comes in and requires rubber/wheels fitted, I must fit the correct tyre/wheel to suit the vehicle, otherwise I am responsible for any issues that crop up as a result of an incorrect tyre/wheel being fitted.

    There’s a rim-width issue though, isn’t there? In most states, only 1” wider than “standard” is allowed?
    I mean the definition of “standard” is potentially what’s being argued here, innit? ie. whether an Omega can fit wheels 1” wider than a GTS is a question; but if we take a Honda Accord which was only ever fitted with 6.5” wide wheels, then only 7.5” wheels can be fitted (assuming no fouling & the same offset)?
