Jap Tyres And Compliance...

[SSHatch]

Posting here as well as the tyre section.

Been looking through threads left right and centre.

Maybe I am not typing the right thing in to the search with but I cant locate the answer.

So please, either flame me and provide links to all the threads you found when you carried out a simple 10 second search to prove it can be done or simply let me know what the difference is.

I ask because nobody I have spoken to has been able to give me a clear answer on what is the main difference between a Jap spec tyre and and Aussie tyre that prevents an imported car being registered with the Jap tyres still on it.

Had many varied responses along the lines of the load rating is missing

eg: 245/40 R17 W instead of Aussie spec 245/40 R17 97W

That there is a DOT number not moulded into the Jap ones that is on the Aussie ones.

The the Jap tyres simply are not load rated high enough (highly doubt that one)

So please, if anybody has a clear simple answer to this question then please post up.

i would say the best possible answer is there really is no differance we all import our tyres from all companys world wide yes there maybe some DOT stamped on tyres i have seen many here with dot samps and many without but this makes the tyre no differant from 1 stamped without from the same maker and brand type.

Prevention of registration was brought about due to the quaility control was almost nil and a lot of importers would sell the cars with faulty tyres still on them IE as in Japan we have Snow tyres (very dangerous on hot climate with highway speeds) Most other brands are also sold here even US and korean and chinease makes ive seen here in japan for sale so all tyres that are a few years old driven in the snow tend to freaze in japan and driven thus causing small cracks in the tyre (i call these snow cracks) if you have ever seen these tyres from here they can look in very good condition but minor snow cracks on the surface, the cracks allow moisture into the internal structure of the tyre so example if you have tyre made from Textile fabric or steel cord this creates a problem with reliabilty of the structure of the tyre, the fabric tends to rot inside with heat and moisture and in the case of steel belts lets say the rust and may break in both these case the rubber tread will seperate from the fabric or steel belts in side the tyre.

Any way due to the control of this was intended to be the compliance company and in most cases no one ever replaced good tyres with snow cracks and as you can imagine an accident at 100klm or more with a seperated tyre would cause accidents. these cases have caused the new regulations to make it that all newly imported Japanese imports be fitted with new tyres prior to registration and to be part of the Raws compliance to show you have replaced tyres on all cars you have complied.

Hope this answers your question.

+ 1 for PRIMO's response.

There is very little difference depending on the pattern and or application. A lot of the tyres available in The Australian market are in fact manufactured in Japan.

Tyres in the Australian market will usually be marked either with "DOT" Department of Transport - USA or the E marking system - European ECE regulation 30 for passenger vehilces. The E mark is a lot smaller and is easily overlooked.

So if the tyres that were on my car when it was imported are in fact marked exactly the same as a set of tyres I currently have on my personal Australian vehicle and there are no visible signs of deterioration or damage etc, whats to stop me from leaving them on the vehicle and using them??

Hypothetically of course. Its one of those long winded discussions that I seem to get in regularly and we can never find a black and white definitive answer to the very basic question.

Absolutly nothing is stopping you if it has the correct markings ..it is your personal property and you did follow the rules and registered your car with compliance tyres fitted right.... but i have heard of insurance companies kicking up a stink in insurance claims if there is no DOT on your tyres.

Sorry I probably didnt type exactly what I was trying to get across.

If the tyres on an imported vehicle have the DOT markings and everything else exactly the same as tyres that are purchased here in Australia then what is wrong with leaving those tyres on the vehicle and allowing it to go through compliance and registration with the Jap tyres still fitted??

I understand its all about political mumbo gumbo and the like but I fail to see why a person should have to pay for a second set of tyres to put on a vehicle exactly the same as the ones coming off it just so it can be complied and registered.

[PRIMO]

No its illegal to comply a car with japanese tyres fitted. so to comply your car you will need to fit new tyres no way round it..

[SSHatch]

But this then brings me back to my original question...

Why???

If the Japanese tyres are removed and replaced with identicle tyres bought in Australia whats the difference??

I understand its illegal, I just dont understand why. There is no logical reasoning for it.

the explanation is in my 1st post .... its all about the safety.
