This is a guide to help you read the basic measurements of a wheel. Wheel measurements are generally broken up into three numbers (Wheel Diameter, Wheel Width, & Wheel Offset.) Below we explain how to read and understand each measurement.

Wheel Diameter – When looking at wheel sizes this is usually the first number you will see and represents the overall diameter of the wheel. This is measured in inches. (i.e. 16″, 17″, 18″, etc)

Wheel Width – The second number you see represents the width of the wheel. Similar to the diameter this is also measured in inches. (i.e. 8″, 8.5′, 9″ etc)

Wheel Offset – The third number you see represents the offset of the wheel. The offset is the measurement of how far the hub is mounted out from the wheels center point. This is generally measured in mm and is displayed as a positive or a negative number. A positive number offset means the hub is mounted closer to the outside than the center point. A negative number offset means the hub is mounted closer to the inside than the center point. (i.e. +35mm means that the hub is mounted 35mm closer to the outside than center) The center point of a wheel would be displayed as 0.
