Well done! Well said! Text book, I might add.Ozwald said:offset and bolt pattern are two completely different animals. KDW is correct, S10s have a 5x4.75" bolt pattern but the offset is the distance from the center of the wheel to the mounting surface. The proper offset depends on the width of the wheel you are trying to put on.
You can get adaptors to change from 5x4.75" to 5x135mm but then you need to factor in the thickness of the adpator when deciding on the offset of the wheel.
