Hi i went to look at getting bigger rims and a mag shop chick pulled out a book and showed me that '89 till about '94 (something like that) is limited to 17inchers and 225 or 235 or soemthing she said that it is a restriction on the model and then went on to show me the restrictions on all the different cars including gtr's and late model z32's (which by the way can take some big wheels) anyhow, to the point, she said that if i get bigger wheels than the ones that are specified as the max for that vehicle, then the car is effectively illegal and thus -> NOT INSURED if im in an accident or woteva I just wanna know, is there any truth to this? is she full of it? i am running with the stock rims currently and i badly want to upgrade them to some 18 inchers with lots more width cheers~
clarification im in WA btw, but i think its probably a national thing (given the nature of it - wheel sizes/safety etc)
Look on the TTZED web site and buy a new tyre placard Pull off the old one stick on new one and presto. Your car takes big wheels. If its an IMPORT no one would know what it was in Japan anyway. www.ttzed.com
Re: Look on the TTZED web site and buy a new tyre placard in sa, you can legaly fit wheels that are 2 inches bigger than what the car came with stock. this goes for any car. this i'm sure of. as far as the width goes, from talking to a few people, they have reflected what was said written on the website clayan provided, 25 wider than stock. the way i see it, if the overall diameter of the wheel changes (rim + tyre) changes, the centrifugal force of the wheel increases and requires more force to stop it, so to make it legal i guess you'd need to upgrade the brakes as well and an engineers report. what i'm saying is that for example, a stock ford falcon which comes with 15" rims could only go up to 17" aftermarket rims with the stock brakes, while xr's and gt's with factory fitted 17" and bigger stronger brakes can fit 19" legaly. to stick 19" on the stock falcon, you'd also have to fit the same or better brakes as the xr and gt ones. hope that makes sense. best thing to do is call the transport department in your state/territory and speak to someone about vehicle modifications. for everyone in south australia, if you got any questions about vehicle modifications, here's the contact Transport SA Vehicle Standards Team Regulatory Services Kateena St Regency Park 5010 Ph 1300 882 248 Fax 08 8348 9533 Email vehicle.standards@transport.sa.gov.au probably a good idea to get a contact for each state/territory and put it in the technical section/faq.
Yes she is correct, HOWEVER..... 25th Anniversary models came out with 17" rims, so it is legal to go up 1" from there to 18" rims. (Technical argument, perhaps.) What you need is a replacement tyre & rim label from TTZ in Melbourne( which you place on the Drivers-side Door Pillar) listing 18" rim sizes, then if you have to argue with someone, just point at that and act dumb.:LOL::LOL:
Re: Yes she is correct, HOWEVER..... i don't know how much the 25th anniversary models differ from the normal production model , but if they came with 17" rims from factory, legaly you can go 2" bigger, up to 19", so fitting 18" rims would not be an issue. even on the base model that comes with 16" rims you can legaly fit 18's.
OMG I have no idea what you are all talking about I bought a set of 18" ROH Drift R with 235 front and 255 back and i am insured with Just Car and have told them of ALL my mods and have no probs with wheels been insured. Mine came with 17" BBS wheels but i'm sure that had nothing to do with it. Anyway a mate just got some spiffy new 19" wheels with FAT rubber and brake upgrade, the works etc Has no problem getting insurance and has told them of all his mods too ??? He was getting 20" but the tyres were so expensive he got 19" NSW is the biggest bunch of twats when it comes to insurance, as bad as Vic is with the cops pulling everyone over for having the wrong "look" about their car, so why i have no probs getting insured ??? no idea ??? i don't follow what you guys are saying ??? WA has like the least amount of rules compared to other states... have some real btchy ones but generally less on average so why 18" wont be allowed ??? How about ringing an insurance copmany in WA and asking if they will insure 18" wheels ???
Insurance companies don't determine whether mods are legal or not ...>> It's the motor registry authorities. With insurance companies, it's up to you to ensure that the mod is legal. Even if you've got an insurance approved mod, if you have an accident and they find out that the mod is illegal they can deny the claim.
RE: OMG I have no idea what you are all talking about Not only do you "not know what WE are all talking about", but I seriously doubt that you know what YOU are talking about either.:LOL::LOL::LOL:
Thanks for the link Claymen ok guys, i did some research today and this is what i found out: firstly, the tyre placard that i have in my glovebox says 300zx on the top etc but its different to all the ones on the ttzed site. Mine has the following written on it: Rim Size Tyre Designation 8.5J, 9.0J, 9.5J, 10.0J 255/40R17 and then it goes on to list tyre pressures. That line that i typed out is also just one line of about 6 or so combinations listed on the sticker. now, back to WA regulations. it seems you can't get wider rims, but going by that 10.0J on my sticker it means i can get 10inch rims. There are lots of rules that the increased wheel size can't result in the wheel fouling against the vehicle body and vehicle handling not being impaired. then it goes onto something called "plus one" and "plus two" which i presume means going up 1 inch or 2 inches on the rim size. But then it says "all tyres and rims fitted to the vehicle are of the same size and profile" which i presume means that if you have different sized rims/profile on the front and rear of your car, then technically YOU ARE NOT INSURED COS ITS ILLEGAL (in bold because thats important and you should check it out if that applies to you) and a final point is that you can't reduce the wheel track at all, and you can't increase it by more than 1 inch. Which means that the distance between the 50% mark on the width of your tyres can't increase by more than 1 inch. So if you're buying bigger rims, then the dimensions of where the "bolts" meet the wheel relative to the wheel width is a factor. But thanks for the help guys, im now in the market for some 9J or 10J 18inch wheels with some phat 255/35R18 rubber~
