Yokohama Rubber has begun testing an AI based technology to measure tire pressure using tapping sounds. This approach aims to improve vehicle safety, reduce costs, and enhance operational efficiency by streamlining tire air pressure management, Yokohama said.

Challenges with Current Tire Pressure Checks Daily air pressure checks for truck and bus tires using pressure gauges often cause valve failure or air leakage. Real time monitoring systems are effective but costly. As a result, tapping tires with a hammer remains the most common method. However, accurately determining tire pressure by sound is difficult, even for experienced drivers, highlighting the need for a simpler and more precise solution.

Yokohama AI Based Technology Development for Tire Safety Yokohama Rubber, in partnership with METRIKA, is developing an AI based technology algorithm to improve tire pressure checks. The algorithm distinguishes tapping sounds from environmental noise, analyzes the sound's timing and duration, and estimates tire pressure.

The technology enables drivers to use a smartphone app for visual assessments of tire air pressure. This eliminates the need for specialized devices or advanced skills, offering a user friendly and efficient solution. Future Plans to Expand AI Applications Yokohama Rubber plans to refine the AI algorithm and application during practical testing.

The company aims to integrate the technology into its next generation Tire Management System (TMS), which leverages IoT to recommend products and strategies to transportation companies. Yokohama AI Based Technology Supporting Sustainable Logistics Yokohama Rubber focuses on developing technologies that are aligned with the global shift toward electric and autonomous vehicles. The company remains committed to creating advanced tire solutions that support sustainable logistics and improve operational efficiency for transportation industries.
