i was talking to my mate who used to manage a tyre shop and he was saying that all the aftermarket wheels that come into the country on imports are illegal due to not being load rated high enough. apparently most wheels made in japan other than stock wheels aren't load rated high enough.

has anyone had problems with this when it comes to insurance claims and things like that?

wheel load indexes? i didnt even know they had them.. Although i have seen a helluva lot of mis-loaded, illegal imported tyre combo's. Are The wheel load indexes the same amounts as the tyre load indexes? Ive never heard of an incorrect wheel indexing before, but plenty of tyre indexing.

yes i know it is all about rolling diameter.

ok, i had a chat to my mate and got the info. it is about the load rating of the wheels. a lot of import wheels haven't had any load testing done. if you look at australian wheels have a JJ or JJJ rating after the size. and the reason why they don't ploice it is because the japanese manufacturers caust on and started stamping their wheels with it, even if they haven't been tested so they don't police it.

it is one of those things, they got out smarted by the manufacturers and there is no way to test it without destroying the wheels so they gave up.

the whole "20 inch wheels are illegal on most cars" thing... is wrong.

its all about rolling diameter fools!

you are wrong there .

well in west australia anyway

we have whats called a plus 1 and plus 2 rule

that means you cn only go up to 2 inches over factory size

eg... r32gtr comes out with16 x 8 rims can legaly only go to 18 x 8 rims .

we cant go over 8 inches wide law here states that ya can only be wider than 7 inches if your vehicle came from factory with wider than 7 inch and if it did you cannot go wider than genuine factory width which is stated on the tyre placard inside the passenger side door

well my jap spec rims are rated at 680 kg load each when the stock gtr rims are rated at 650 kg each so my jap spec aftermarket rims are actually stronger than factory nissan rims

and 20" wheels aren't legal on most cars.

That's not the case on the eastern seaboard (I've checked the VSI documents for NSW, Vic and Qld).

I could put 20" diameter rims on a MGB if I could find the right ones, and get tyres for it.

    • I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though 
    • $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
    • Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.
    • I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.
    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
