was just wondering if it is safe to put 1985 15"trx bluebird rims onto a 90 trx pintara with 14"rims ,i notice in car magazines they have seperate FWD only wheels for front wheel drives and offsets between the wheels would also have to come into the question, any one else done this?or am i just better off getting 16,17,18"rims?

Im pretty sure its fine. 16inch wheel is the biggest legal wheel u can put on it. That being said, most people have 17s (myself included) and mine are from an import silvia.

17inch rims are legal.

Using this tyre calculator http://www.miata.net/garage/tirecalc.html

and this as a guide for qld... http://www.transport.qld.gov.au/resources/file/eb57c508de5dea8/Modification_jan05v2.pdf

The rim diameter may be varied from the standard size
but the overall diameter of the tyre must not vary by
more than +15mm or -26mm.

and

The maximum tyre width for a car or car derivative must
not be more than 1.3 times the vehicle manufacturer’s
widest optional tyre.

Doing some quick calculations you can have a 235/40/17" tyre legally.

My bad. I was told that u were only allowed to increase your rim size 2inchs from standard.

Nope its just a myth.

If you have insurance its always good to check with them as to what they'll cover. Most of the time they will only insure wheels 1" wider than stock.

its is... TRX's came out with 15" rims standard.

The general rule is 2 up and 1 out.

Two inch's larger in diameter (from the largest wheel in the range eg. I can put 17's on my Ti, even though they came with 14", because the TRX came out with 15")
One inch wider

Depends on the law for modifying in each state jecks.

If you read the guide for qld from the link i posted legally i could put on 18s on my car providing that the diameter of the tyre, not the rim, is no more that 15mm larger or 26mm smaller.

Jecks · « **Reply #7 on:** Apr 28, 2008, 01:27PM »

oh ok, well i guess my rule applies to vic

Kranzy · « **Reply #8 on:** Apr 28, 2008, 02:16PM »

I think you'll find that the rule will be a rule of thumb sort of thing. Reason im saying that is the rule for modifying must relate to the tyres overall diameter as that is what changes the speedo etc...If you have 14" stock rims, and put 16's on it with massive tyres that could put your speedo out by 10% thats not going to be legal just because you have 2" larger rims on it.

I have a set of the 80's TRX rims on my car. Think you may beable to see them somewhere in my project thread (click link in my signature).
These fit perfectly as they have the same width and offset, just 15"
They've been good, not really much difference from the stock 14" 90 TRX rims though, just look a bit different.

If you are after some cheap rims with a bit of character, and cheap tyres... these are great. If you want the car to look pimped out go for 17" with expensive low profile tyres.

Pretty sure Vic is the same... Rolling diameter is what matters. At least it had better be since i've got the same rims as you waiting to go on

Well like i said that was out of the vehicle modifications booklet for queensland. Im sure Vics would be pretty similar but doubtful it will be exactly the same, check on vic roads or whatever it is to see if they have an outline for modifying cars.

Guide can be found here...

In Vic its 15mm larger than biggest wheel available for that model or series or 15mm smaller than the smallest wheel available for that model or series.

The general rule is 2 up and 1 out.

Also in terms of wheel width, the rim cannot be more than 25mm wider than stock. So just over an inch

I run some form of old bluebird trx rim on my pinny but i have no idea what year they are.

wombat · « **Reply #16 on:** Apr 28, 2008, 07:28PM »

all the old bluebird (wirespoke looking 15x6) ones are the same, it was only if the centre cap said Nissan or Datsun.

They fit R31, I know that much. U12 should fit no worries. The 'Factory' tyres they want are 195/65R15, which are expensive. Run 205/65R15, cheap as - Falcon and Commodore spec - big volumes.

SSS · « **Reply #17 on:** Apr 28, 2008, 10:42PM »

Letting out the inner muzza here...but i always thought that VN-VZ steelies in black would look good if the centres could be safely modified to 4 stud.

Luke · « **Reply #18 on:** Apr 29, 2008, 12:45AM »

I had 1984 Bluebird TRX rims on my U13 attesa for a few months, fitted well and looked alright too. In SA the Law is deffinately no more than 2 inches bigger, I've had cops try to defect me several times for having 17's, only to read the tyre placard to see it says 15's standard.

BILL*69 · « **Reply #19 on:** May 1, 2008, 12:17AM »

Yeah the SA law is definately 2 inches.

bones · « **Reply #20 on:** Jun 18, 2008, 02:25PM »

quick question then, if anyone knows the answer...mate of mine has got 17*7s on his r31 skyline [aus spec] and wants to sell them to me...

Mainly depends on the offset. Does he know the offset?

no. at least we dont think we can find out either, is it just gonna be one of those things where you have to throw them on the car and see how it goes?
