Hi guys, I am trying to get a set of steel wheel for a 1992 75 series pickup. I came across this set locally. But I am not sure about the offset. The seller can’t tell me the ET number. He doesn’t know the offset too but he sent me a photo. From the photo I am not sure what the offset is. Maybe you guys recognize this wheel and can tell me if it will fit on my car. I don’t intend to use spacers. And I read on the forum (the chart is from someone posted on the forum) that for 3.5” backspacing with 15x7 wheel, the offset should be -12. I am not sure if I get that right.
