I am in the process of selling my winter wheels as am thinking of buying a merc. as can be seen in the photo no mention is made of the ET but there is a IS number there. Are these the same thing?

You can measure the offset. Put a straight edge across the rim and measure distance down to the face. Take half the rim width off that and that should be a good estimate for ET.

OP was asking about the et which is a measure of offset.

Measure the rim width rather than using the nominal value, because you'll be using the outside width not the width between beads.

Might mean the wheel is inset 37mm. Does that look about right for that wheel??

Thanks to everyone who replied. I used the code on the wheel which gave me the style and the et, which is 37.
