Wheel Offset Calculator

Image showing location of the location of an offset

Use this calculator to determine the effect of changing your wheel width and offset. First enter your current wheel width and offset. Then enter your new wheel width and offset. Next click the calculate button. It will show the clearance between the inside of the wheel and the strut housing. It will also show how far the outside of the wheel edge will extend or retract. If you reduce the inner clearance too much or push the wheel out too far, the tire might rub or not fit at all. This calculator is for information purposes only and we do not guarantee fitment based on this calculator alone.
