Tire Information
ATV Wheel Sizing and Offset. To determine the diameter of a wheel: Measure the width of the bead area of the wheel (not the outer rim). In the diagram above, the diameter measures 12 inches. To determine the offset and width of a wheel: Measure from the center weld to the center of the tire bead area on both sides of the wheel. The outer measurement will be the one with the valve stem.
