Wheel offset is crucial for ensuring proper fitment and performance of your ATV wheels. Here’s how you can measure the offset of your ATV wheels:
Step 1: Understand Wheel Offset
The wheel offset is the distance from the wheel's hub mounting surface to the centerline of the wheel. It can be positive, negative, or zero:
Positive Offset: The hub mounting surface is closer to the outside (street side) of the wheel.
Zero Offset: The hub mounting surface is exactly in the center of the wheel.
Negative Offset: The hub mounting surface is closer to the inside (vehicle side) of the wheel.
Step 2: Remove the Wheel
To get an accurate measurement, you need to remove the wheel from your ATV. Make sure your vehicle is on a stable surface and use appropriate tools to remove the wheel.
Step 3: Measure the Overall Width of the Wheel
Lay the wheel flat on the ground and measure the overall width of the wheel from outer edge to outer edge. This measurement is the total width of the wheel.
Step 4: Measure from the Mounting Surface to the Inside Edge
Next, measure the distance from the hub mounting surface to the inside edge of the wheel (the edge closest to the vehicle when the wheel is mounted).
Step 5: Calculate the Offset
To calculate the offset, use the following formula:
Offset = Distance from Mounting Surface to the Back Edge - (Width of Wheel / 2)
If the offset is positive, the wheel has a positive offset; if the offset is negative, the wheel has a negative offset.
Conclusion
Knowing how to measure ATV wheel offset is essential for proper fitment and vehicle performance. Make sure to double-check your measurements for accuracy.
