Tokyo (July 22, 2024) - Japan Airlines Co., Ltd. (hereinafter referred to as JAL) and Bridgestone Corporation (hereinafter referred to as Bridgestone) have expanded the application of tire wear prediction technology to implement scheduled tire replacement operations for large jet aircraft, including the Airbus A350-900, which has been operated by JAL since May 2024.

Tire Wear Prediction Operating Procedures

Aircraft tires must have guaranteed safety and security and ensure the takeoff and landing of aircraft under harsh conditions, including heavy load, high speeds, and a wide range of temperatures. Typically, aircraft tires need to be replaced after several hundred takeoffs and landings. However, the rate of tire wear varies depending on a variety of factors, such as the usage conditions for a given aircraft or at a given airport. This condition has made scheduling tire replacements difficult, leading to replacements being treated as an unscheduled task, which can result in the sudden need to replace tires or multiple tires around the same time. To address this issue, Bridgestone partnered with JAL to develop operating procedures that enable scheduled tire replacements. By combining JAL's aircraft insights and flight data with Bridgestone's tire expertise and digital tire wear prediction technologies, highly accurate predictions of the optimal time to replace tires have been formulated. Since May 2020, these procedures have been in place for the regional jet aircraft operated by J-AIR Corporation.

With four years of experience, the use of these procedures has contributed to improved efficiency in tire replacement operations, lower and more consistent stocks of tires and wheels, as well as subsequent reductions in CO₂ emissions from the production and use of such items. Moreover, tire replacement operations have transformed from an unscheduled task into a scheduled task with the accurate prediction model, which has also contributed to reforming the workstyles of maintenance staff by reducing unscheduled overtime while also improving the quality of maintenance through the expansion of preventive maintenance.

Based on their combined expertise and insights, JAL and Bridgestone have advanced tire wear prediction technology and its applications. The use has been expanded from being limited to specific regional jet aircraft to now include large jet aircraft operated by JAL.

Looking ahead, JAL and Bridgestone will continue such collaboration in order to create new value, which contributes to the development of the aviation industry.
