Default How do I find out what size lug nut I'm using?

I'm using OZ SL. How do I find out what size replacment to get? The nuts I'm using says RH 1.25 on it, what does that mean?

It means they are Right-Hand-thread (see also: normal) and 1.25mm per turn. There should also be a 12mm around somewhere.

You can check the size by going to any auto store with the lugnut and comparing them to the display gauges where the lugnuts are sold.

Subarus use 12mm x 1.25 RH.

Our wheels use "Acorn" style lug nuts. The stock lugs are standard size, but many aftermarket wheels, including my OZ P1s have an extended seat area so that you can use "Acorn Bulge" style lugs to give you a bigger contact area.

good info

I have 17" Technomagnesio wheels now, and the stock lugs tighten down so far, that the socket grips half the lugnut when tightened down.
