Method for determining a magnitude of a mass to be placed on a wheel assembly using acceleration data

A method for determining a magnitude of a mass to be placed on a wheel assembly using data from one or more inertial measurement units (IMU's), the one or more IMU's being mounted to a removably attachable object that is attached to a wheel of a vehicle in a manner that inhibits the object from coming off of the vehicle while the vehicle is in motion, each of the IMU's including an accelerometer, wherein the one or more IMU's rotate with the wheel assembly while the vehicle is in motion, the method comprising:

• (a) collecting a set of acceleration data from the one or more IMU's that rotate with the wheel assembly,
• wherein the set of acceleration data is collected while the vehicle is in motion;
• and
• (b) applying the acceleration data to a predictive model to determine the magnitude of the mass.
