Sumitomo Rubber’s Proprietary Software Technology SENSING CORE Adopted for the First Time in Japan: Standard Equipment on Isuzu Motors’ New Heavy-Duty Truck “GIGA” with Wheel Detachment Prediction Detection System
Oct. 29. 2025
Sumitomo Rubber Industries, Ltd. is pleased to announce that its proprietary sensing technology “SENSING CORE” has been adopted for the first time by a Japanese automaker and is making its debut in vehicles going on sale on October 29. Sumitomo Rubber has been developing SENSING CORE that is designed to detect the condition of tires, vehicles, and road surfaces, as part of its efforts to address various challenges faced by today’s mobility society.
The technology is featured in Isuzu Motors Limited in its new GIGA*1 heavy-duty truck, which comes standard with SENSING CORE’s “Wheel Detachment Prediction Detection System.” The model will make its public debut at the Japan Mobility Show 2025,*2 one of the country’s largest automotive exhibitions, which is opening on October 30.
Overview of SENSING CORE technology and value it provides
SENSING CORE is a software technology that analyzes wheel speed data generated by tire rotation, together with CAN data (vehicle control information) transmitted through the vehicle’s control system, to detect various tire and road conditions, including tire pressure, Tire wear, Tire load, and signs of potential wheel detachment. The Wheel Detachment Prediction Detection System installed in the new GIGA model is designed to detect the loosening of wheel nuts while the vehicle is in motion; if an abnormality is detected, the system alerts the driver through a warning message and a buzzer. This capability allows wheel nut loosening to be detected even while driving, complementing conventional inspections and driver experience, and is expected to play a significant role in preventing wheel separation accidents.
How Wheel Detachment Prediction Detection works
Takeshi Asakura, Executive Officer and General Manager of Automotive System Division at Sumitomo Rubber Industries, stated: “We are delighted that SENSING CORE has been adopted in Isuzu Motors’ new GIGA heavy-duty truck, contributing to enhanced vehicle safety. Moving forward, we will continue to expand its use to more models, delivering on Sumitomo Rubber’s philosophy of creating ‘a future of joy and well-being for all’ and supporting the advancement of mobility society.”
Overview of the model featuring SENSING CORE
The new GIGA achieves a high level of economy, comfort, safety, load capacity, and operational stability. Equipped with advanced braking and steering assist functions designed for the era of autonomous driving, the truck helps prevent and mitigate accidents and ensures stable operation. Along with its completely redesigned cab design, GIGA contributes to the growth of customers’ business and logistics operations. The target sales volume is 12,000 units per year.

Wheel Detachment Prediction Detection System: Background
According to the Ministry of Land, Infrastructure, Transport and Tourism, there were 120 wheel separation accidents involving heavy-duty vehicles in 2024, many of which occurred after vehicles were fitted with winter tires, and some resulted in fatalities.
The Japan Automobile Tyre Manufacturers Association (JATMA) has been strongly encouraging that basic measures should be taken during vehicle maintenance, such as proper inspections and retightening of wheel nuts, in order to prevent wheel separation accidents. Meanwhile, as it can be difficult for drivers to notice loosening of wheel nuts while driving, the development of technology capable of detecting early warning signs has been a key challenge for the industry.
For many years, Sumitomo Rubber has been developing a range of technologies with a focus on tires. Building on the expertise gained through our "Deflation Warning System (DWS)", we have been making strides in the development of SENSING CORE, which is expected to create diverse value in the next-generation mobility society. And the Wheel Detachment Prediction Detection System, one of SENSING CORE’s key functions, has now been put into practicalapplication.
