Wheel Offset Calculator

Check our wheel offset calculator to determine your proper wheel fitment.

Wheel width and wheel back spacing is very important for proper wheel fitment.

 

Use this chart to determine wheel offset using back spacing measurement

Step 1 -
Measure wheel width
 
Step 2 -
Determine the back space measurement by laying a straight edge across the bead seat of the inside edge of the rim, and measuring from the hub flange to the straight edge.
 
Step 3 -
Using the chart below, find where the row for the wheel width intersects with the column for the back spacing measurement. This is the wheel offset.
 

 

* Please note, for Optimum tire fitment with our leveling kits, we recommend a +12 wheel offset for custom wheels.
