Tire Tread Wear Prediction

Estimating tire wear using AI models to detect uneven wear at an early stage. The method involves capturing images of a tire's tread from the front, inputting them into trained machine learning models, and deriving outputs indicating the degree of uneven wear. One model estimates overall uneven wear, while another estimates groove depth. By combining the outputs, it determines if the tire needs replacement. The models are trained using labeled images of actual tires at various wear levels.

Method for predicting the remaining life of a tire on an aircraft before replacement. The method involves tracking the wear of a specific wear indicator in the tread of the tire. The wear indicator is a feature with a known shape and location in the tread. By monitoring the appearance of the wear indicator as the tire wears, the remaining life can be estimated. This allows anticipating when the tire needs to be replaced without relying solely on direct visual inspection of the tread height. The wear indicator provides a more reliable and predictive measure of wear progression.
