The approach, for example, involves determining sensor data from a magnetometer, an accelerometer, or a combination thereof associated with a vehicle. The approach also involves processing the sensor data to determine a rotational frequency of at least one tire of the vehicle. The approach further involves calculating a speed, a tire/wheel diameter, a safety condition, and/or a maintenance condition of the vehicle based on the rotational frequency and providing the speed, the tire/wheel diameter, the safety condition, and/or the maintenance condition as an output.",
