Hi could anyone tell me what size and back spacing will fit my 95 fairlane ghia?
i have found a set of convo pros 15x8 with 3.5" backspace and 15x6 with 3" backspace
rear tyres are 15x245 and fronts are 195's
will these fit?????
cheers Anthony

They should be close, the only thing you have to watch is that the inside of the 15s dont catch on your brake callipers , especially the front. I went up to 19 inch on mine with a 30mm spacer front & rear. 3" spacer may be too far outside your guards, but the only way to know is if you can try one on before you buy. It may be an expensive exercise to just guess as most wheel offsets are not the same. See my gallery photos to see what i mean on the blue NC V8.

Hi,

backspacing is not so common with modern vehicles... its more offset your worried about... Back spacing is a more common way to measure older vehicles without uprights...

For you 95 lane your talking NF I imagine?

So your chasing a PCD of 5x114.3mm with a positive offset somewhere around the 6 to 11 mark... if they are high 30's or 40 then no they wont fit they will hit on the uprights... Although being unusually narrow on the front they may still fit, depends... check the offset first... 6 to 11+ definitely too much more, its hard to say...

depending on your state regs you can run spacers if the offset is too great to push them out away from the uprights...

From memory they will fit.
When I looked into it when I was first looking at getting riddlers for mine (a dream that will come true one day) we worked out that the backspacing/offset that will work on an XD would work on my NF.
Somewhere on the net is a backspacing to offset calculator that was pretty accurate.

if you knew how wide the outside of the rims were I could convert it for you, but I'm sure wheel width is measured to the inside of the rim, not the outside, back spacing is measured from the face to the back outside of the rim... so once you know the outside measurement is fairly straight forward...

Cheers,

Thanks everyone for the replys. i called a prefomance shop in dandenong victoria today and they said 3 to 3.5 will fit. so im buying the convo pros.
i will post some pics of my ride once they are on and its lowered.
its got a hp 5 ltr with a solid cam rollers and about another 6 gees plus spent on the motor with a 3000 convetor shift kit and about to put a set of 4.11 in the rear
should be a nice cruizer. except for the fuel bill as its very thirsty even at present.
