A tire failure prediction system includes a setting unit configured to set a predetermined master curve indicating a relationship between a speed of a vehicle on which a tire is mounted and a heat build-up temperature of the tire, a determination unit configured to determine a tire condition of the tire based on a difference between the master curve set by the setting unit and a measured value of the heat build-up temperature of the tire, and an update unit configured to update the master curve set by the setting unit. The update unit updates the master curve in a case where the determination unit determines that the tire is normal. In a case where the determination unit determines that the tire is abnormal, a warning unit outputs a warning.

This disclosure relates to a method and system o real time prediction of tire remaining useful life using a tire digital twin. Herein, the digital twin of the tire monitors a plurality of tires while accounting for runtime as well as parking operation of tires. During runtime, tire goes through multiple operational changes, therefore, the system is configured to estimate the operational changes. The estimation is done in the form of index, which is compared with the manufacturers' recommended value. Similarly, while vehicle is parked, tire still goes through changes which play an important role in its overall health, like, long pending wheel rotation can lead to flat spot. Tire inflation can change owing to cool down effect as well as uncontrolled natural leakages. Further, these parameter indexes are clubbed together to calculate the health index of the tire, which is used to estimate the tire's current remaining useful life.
