Modern vehicles generate extensive tire data during operation, with sensors measuring load distributions, surface temperatures, and contact patch dynamics at frequencies up to 100 Hz. These measurements, combined with vehicle dynamics data, create a complex picture of how tires wear under real-world conditions—where tread loss can vary from 0.001 to 0.004 mm per kilometer depending on driving patterns and environmental factors.

The fundamental challenge lies in accurately predicting tire wear rates and remaining tread life while accounting for the massive variability in operating conditions, road surfaces, and driver behaviors.

This page brings together solutions from recent research—including thermal-based wear monitoring systems, machine learning models that leverage sensor data, statistical approaches for remaining tread prediction, and real-time load estimation techniques. These and other approaches aim to provide reliable wear predictions without requiring frequent manual inspections while enabling proactive maintenance scheduling.
