Enter the measured backspace (in) and the wheel center distance (in) into the Calculator. The calculator will evaluate the Car Rim Offset.

## Car Rim Offset Formula

CRO = MB - WCD

Variables:

- CRO is the Car Rim Offset (in)
- MB is the measured backspace (in)
- WCD is the wheel center distance (in)

To calculate Car Rim Offset, simply subtract the wheel center distance from the measured backspace.

## How to Calculate Car Rim Offset?

The following steps outline how to calculate the Car Rim Offset.

- First, determine the measured backspace (in).
- Next, determine the wheel center distance (in).
- Next, gather the formula from above = CRO = MB – WCD.
- Finally, calculate the Car Rim Offset.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

measured backspace (in) = 4.234

wheel center distance (in) = 1.23
