Offset Calculator



Use our wheel offset calculator to help you determine what wheels may fit your car and how much room you have to work with. Changing rim diameter (for example from 16" to 17") doesn't affect offset calculations. The generated numbers represent the difference in inner clearance between the current and new wheels, and also how far the outer edge of the new wheels will extend or retract compared to the current wheels.


DIRECTIONS:

1. Enter your current wheel width and offset.


2. Enter your new wheel width and offset.

3. Click the Calculate button.
