5x4 Bolt Pattern Aftermarket Options

Wheel measurements are a mess the way they are specified. Offset in millimeters, width and back space in inches. Unfortunately for metric system haters like me, everyone talks about offset.

For wheels with tires mounted, I use two pieces of wood, one on either side, measure between them and subtract 1/2 inch for the width.

If you also measure the back space, the offset is easy to calculate, then convert to mm.

It’s pretty much impossible to search for aftermarket wheels without knowing the offset you want.
