Ok i can get me a set of 1 month old 20's now they came off a BA falcon with SSSL SSL springs and they scraped they are 245/35/20 i cant be ****ed pulling my wheels off and trying these on unless i know for sure they will fit.

So 245/35/20 to wide?

What's the offset?

How would i find that out

How would i find that out

On the back of the wheel

thanks ill find out monday

ok so they are
245/35/20 +40

all magna falcon and commodore are +40

245/45 tyres on 18x7.5" rims fit on my car - 2003 AWD TJ SII

You will also need to know the width of the wheel to know if it will fit.
eg: if this happens to be 20x10 I'd say it probably won't fit and it won't be legal.

If your car's tyre placard shows 7" wide wheels as an option, then 8" is the max legal width in NSW. I think other states are the same, but not 100% on that.

If they are 20x8 +40 then it should fit, but you should test fit to be sure before you hand over the $ :)

p.s. are you sure about commodore being +40? I've just never noticed commodore measurements before becuase their PCD isn't compatible with Falcon/Magna.
We've got 5x114.3 and they've got 5x120 or something (112?).

Holden wheel stud patteren is different to fords, so they won't fit. Magna, ford and toyato wheel stud are the same. But if I'm wrong someone will pointed out lol

Best to put them on and try it out, the only way really to be sure. Some people report bad tramlining with low profile 20's, you could test that too. There must be a reason why they are only 1 month old and the owner is selling them. Ask him.

yeah i know commodore are 5x120 +40 as they use a german hub Japanese hub is 5x114.3 +38 or+40 euro hubs are AND subies 5x112.3 +35 i just dont want them poking out like 4x4 wheels, Ill try em out and go from there
