Modern automotive systems rely on multiple independent technologies for braking, stability control, energy recovery, and speed regulation, resulting in increased system complexity and delayed response times. This research proposes a Smart Tire Architecture that transforms conventional tires into intelligent, multifunctional systems capable of enhancing vehicle safety, energy efficiency, and intelligent mobility. The proposed architecture integrates tire-level auto-braking, continuous energy harvesting through piezoelectric modules, gyroscopic balance control, GPS-based speed limiting, and IoT-enabled monitoring within a unified platform. By decentralizing critical safety and control functions directly to the tire, the system reduces emergency response time, improves vehicle stability, optimizes energy utilization, and enables predictive maintenance through real-time communication. The proposed Smart Tire System provides a scalable framework for next-generation electric vehicles, autonomous transportation, commercial fleet management, and smart city mobility infrastructures.
