Was looking at the wheel/tyre doc out for consultation at the moment last night, and refers to the previous multi page fact sheet for tyre to rim sizing?

There are two significant changes which IMO will have an impact on a lot of people The first thing is, basically all wheels having to be hub centric The second is mudguard coverage, the CCM appears to have been updated to bring it inline with the wof VIRM requirements as they are now Problem is, this is currently either largely ignored, or nobody knows about it, as a lot of even factory vehicles dont comply and could mean that a car being certified may need mudflaps added, the way I interpret the wording 2 1 Quote Link to comment Share on other sites More sharing options...
Snoozin Posted July 6, 2021 Share Posted July 6, 2021 When you say hubcentric, does that mean centering rings are permissible or the actual wheel must be hubcentric? Because I don't know of any aftermarket wheels that are even close to most Japanese hub spigot diameters! Mudflaps would be a sick burn.

xsspeed Posted July 6, 2021 Share Posted July 6, 2021 @cletus a "centering system" is a bit vague, one could argue tapered nuts on their own are centering, although it then says if tapered nuts used a close tolerance is "recommended". Presumably hubcentric rings are acceptable? As Richie says, impposibru otherwise Quote Link to comment Share on other sites More sharing options...
cletus Posted July 6, 2021 Author Share Posted July 6, 2021 I looked again and theres a side note on the previous page in a different section so that might cover it I guess if it is acceptable to use tapered wheel nuts to center the wheel instead of the center spigot then that solves half of the issue Not sure where that leaves wheels with shank nuts though, like tridens, hotwires, cragars, etc. I guess they would need centering rings made to suit and attached somehow 1 Quote Link to comment Share on other sites More sharing options...
Testament Posted July 6, 2021 Share Posted July 6, 2021 if the camaro was 8 inches lower it would comply? the way they have demonstrated it looks like they mean it applies to hot rods with exposed suspensions Quote Link to comment Share on other sites More sharing options...
cletus Posted July 6, 2021 Author Share Posted July 6, 2021 That diagram is from the wof virm. So what every car on the road should comply with. It looks like the CCM requirements are being updated to match the wof ones Quote Link to comment Share on other sites More sharing options...

cletus Posted July 6, 2021 Author Share Posted July 6, 2021 Correct, although a mudflap can be considered part of a mudguard according to the definition in the virm https://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general/tyres,-wheels-and-hubs/mudguards Quote Link to comment Share on other sites More sharing options...
cletus Posted July 6, 2021 Author Share Posted July 6, 2021 I dont know when exactly but the virm has been changed at some point in the past few years as that mudguard diagram used to look like this and there was no requirement for a full width mudguard apart from dual wheel vehicles Strangely it's still the same as it used to be , in the motorcycle section Quote Link to comment Share on other sites More sharing options...

Nominal Posted July 6, 2021 Share Posted July 6, 2021 The diagram is in the virm? Here is what the draft lvvta standard says Quote Link to comment Share on other sites More sharing options...
Mof Posted July 6, 2021 Share Posted July 6, 2021 Lvvta was set up by a bunch of hotrod nice guys to give a voice to the general public against the bureaucratic rules of the nzta, to help them see reason and be fair. Imo it seems to me that bureaucracy has taken over lvvta too 1 Quote Link to comment Share on other sites More sharing options...
