Wheel Balancer Measurements – What You Need to Know

When using a wheel balancing machine, the balancer needs two or more key measurements. These tell the machine exactly where to place the weights.

A – Distance to the Rim

• This is the distance from the machine’s face to the inside of the rim.

• On some machines you measure it with the ruler and enter it manually.

• On WB20 and WB30, this measurement is entered automatically.

D – Rim Diameter

• The machine needs to know the diameter of the rim (e.g., 15″, 18″, 20″).

• You can enter this manually, or measure using the pointer on the ruler.

• On WB20 and WB30, this can also be automatically entered.

B – Rim Width

• This is how wide the rim is.

• On some machines, you measure with a width tool and type it in.

• On WB30, the lever sensor measures this and enters it automatically.

Why A & B Matter Most

For aluminium rims that use stick-on weights, the most important measurements are A (distance) and B (width). These determine the correct placement of adhesive weights.

This is why many customers prefer the WB20 — it automates the two most common measurements, making setup quicker, easier and more accurate.
