Notice Regarding the Discontinuation of Karting Tire Supply

  DUNLOP (Company name: Sumitomo Rubber Industries, Ltd.; President and CEO: Yasuaki Kuniyasu) has decided to discontinue the supply of karting tires at the end of 2027. 

Since commencing the supply of karting tires in 1976, we have developed, manufactured, and sold karting tires, earning the support of many customers over the years.
Karting is widely regarded as the foundation of motorsports. In this field, we have supplied tires homologated by the Commission Internationale de Karting-FIA (CIK-FIA), an organization under the umbrella of the Fédération Internationale de l’Automobile (FIA), as well as tires accredited by the Japan Automobile Federation (JAF).
Our products have supported a wide range of karting participants, from recreational drivers to young drivers aspiring to compete in top-level categories, while also contributing to the expansion of karting participation and the development of the next generation of drivers.
We would like to express our sincere appreciation to all customers, users, and related organizations who have used and supported our products over the years.
 
 However, as part of our Group’s medium- to long-term management strategy, and in response to changes in the business environment, we have carefully reviewed the future direction of our business and the allocation of management resources. As a result, we have regrettably made the difficult decision to withdraw from the karting tire business.
 We will continue to supply products to our existing customers responsibly until the end of supply on December 31, 2027.
 We would once again like to express our sincere gratitude to all users and related organizations for their longstanding support.
 
 Going forward, we will continue to contribute to the development of the mobility society through our commitment to motorsports. We sincerely appreciate your continued support.
