I am new on here been looking around but confused the lug pattern is what 4x4.113 4x4.50 or 4x4.100 not only that but i have been lookin around and can't get a clear answer about sizing I have a 72' 240z stock and i want 17' wheels what backspacing do i need and what size tire 205-225, 55-60-65-70.

Any help would be greatly appreciated.

I know this has been asked before and i am sure u guys are tired of answering it for those of us that don't know, so thanks for your time.

Sounds like you're a perfect candidate for some reading! All that is required is, the ability to read english and use a mouse. We have loads of archives that cover just about any thing you may want to know about the old Z cars.

Those are the spacings between each lug nut on the wheel.

As far as I know 4x4.113 is stock lug nut/bolt pattern on all 1969 through 1978 S30 Z's.

The back spacing you need to clear the brakes and such is 4 inches and the Off Set after that point can what ever you like at that point as long as you have 4 inches of back space clearance.

Alot of guys here are running different tire sizes to suit their needs, for example Track use and profile style and such so It'st best to use the Search Function on "Tire Sizes" or "Tire Size" to get a better idea on what the numbers on the side of you tires mean. This part of the subject is a pretty lengthy explanation so to speak but VERY VERY Helpful

I may be wrong on a something here but thats what I understand myself so far.

Here goes a thread to get an idea of whose's running what :rambo:

Actually, that's the number of bolts and the diameter of the bolt circle.

An S30 is 4x114.3 mm which is actually 4x4.5". That's the correct format. 4x100, 4x110, 4x114.3 etc.

thank you very much i do more looking and thanks sblake and wingz
