What Are Offset And Backspacing Wheels

Offset Wheels Are:

Wheel offset is the distance in millimeters from the center line from a wheel to the mounting surface. If the mounting surface is closer to the surface of the wheel it is known to have a positive offset and if the mounting point is closer to the inside of the wheel it has a negative offset. Center or no offset is when the mounting point is directly in the center of the wheel.

Backspacing Wheel Are:

Wheel backspacing is the distance in inches from the mounting surface to the inside edge of the wheel. The width of the wheel originates from the mounting point of the tire beads, therefore the width of the wheel measured from the outside edge to the outside edge is about one inch wider than the specifications. 8 “wheels will measure 9” from side to side, this makes the offset conversion to backspacing not so straight forward. If the 8 “wheel has a middle offset, backspacing is not 4”, it’s actually 4.5 “.

Use our wheel offset calculator to calculate differences in wheel and tire position when switching to different wheel offset / backspacing or tire sizes. Enter your current tire and wheel settings including wheel replacement, then add new settings to compare positioning. The visualizer will display the new settings described in orange, side by side comparisons of two sizes and changes to the speedometer reading. Also calculated are differences in tire diameter, width, aspect ratio, and revolutions per mile along with changes in the main measurement differences. The distance from the top of the tire to the fender well, the inside of the tire to the suspension and frame of the vehicle, and the puncture of the tire are all indicated.

You can also click the Offset Converter tab to convert wheel offset to backspacing and vice versa. Just select the wheel size and start typing offset or backspacing and the equivalent will be displayed. We only use offset input for calculators, so if you know backspacing and not offset, just convert and enter the offset into the fields. We do this because the offset does not require the wheel width to determine the correct wheel mounting surface.

Wheel width will affect the width of the tire by 1/10 “on each side for 1/2” changes in wheel width. This is a small problem unless you plan to run wheel width that is far outside the manufacturer’s recommended range. If you plan to stretch the tire, or run a wider wheel width than the width of the tire, then you must remember that the visualizer shows the tire position not the wheel position. In this case the wheel may be closer / farther from the calculated key measurement distance.
