Positioning: Positioning: Passenger, SUV and light-truck tires; brands Falken, Sumitomo, Dunlop and Ohtsu.
History
The history of Sumitomo Rubber dates back to 1909, when Britain's Dunlop Rubber set up a manufacturing subsidiary in Kobe, Japan, to serve the Far East. Tire production ramped up quickly: the first automobile tire made in Japan rolled off the line in 1913, and the company was formally incorporated in 1917. For decades, the plant remained tied to Dunlop. In 1963, the Sumitomo group took control of Dunlop Japan and renamed the entity Sumitomo Rubber Industries, Ltd. The group then expanded internationally, both through organic growth and acquisitions. The Falken brand was launched by Sumitomo in Japan in 1983, then introduced in North America two years later as a performance- and motorsport-focused lineup. In 2003, Ohtsu Tire merged with Sumitomo Rubber Industries, consolidating Falken and Ohtsu under the group's umbrella. Today SRI operates production facilities in Japan as well as in Indonesia, Thailand, China, Vietnam, Turkey, Slovenia and South Africa. In North America, the group operated a plant in Buffalo, New York, renamed Sumitomo Rubber USA, which produced Falken tires starting in 2016 before closing. A major turning point came in 2025: Goodyear sold Sumitomo Rubber the Dunlop brand and rights for four-wheel tires in Europe, North America and Oceania, a transaction that took effect on May 7, 2025. SRI thereby became the holder of the Dunlop brand for passenger tires in those regions, with certain rights (truck and motorcycle, depending on the market) remaining under license to or owned by Goodyear. In Canada, the group's tires (Sumitomo, Falken, Dunlop) are distributed through wholesaler and retailer networks.
Technologies
Sumitomo Rubber develops several cutting-edge technologies. Its 4D Nano Design technology optimizes rubber compounds at the molecular scale to combine grip, wear resistance and wet traction, notably in the Falken Azenis lines. The group is also recognized for its Smart Tyre Concept, whose ACTIVE TREAD technology—named "R&D Breakthrough of the Year" at the Tire Technology International Awards in 2025—actively adjusts the properties of the tread according to road conditions and weather. The Sensing Core technology analyzes wheel-speed signals to detect pressure, load, wear and road conditions without any additional sensor. SRI also uses silica compounds and hybrid underlayers for stiffness and handling. These developments are backed by the Tire Technical Center in Kobe.
Innovations
Innovation at Sumitomo Rubber is fueled by both competition and fundamental research. The Falken brand, the group's sporting showcase, makes its mark in motorsport—particularly in endurance racing and drifting—which feeds technology transfer into high-performance production tires. On the R&D side, the group has advanced materials modeling at the nanometric scale with its 4D Nano Design, making it possible to engineer rubber compounds that push past the classic trade-off between grip, longevity and wet performance. The Sensing Core technology, presented as a built-in-sensor-free detection solution, opens the door to connected tires. On the sustainability front, SRI aims to use renewable and recycled raw materials at every stage of the life cycle, drawing on its modeling tools and Sensing Core to reduce its environmental footprint. ACTIVE TREAD technology, capable of dynamically adapting the tread to conditions, illustrates this push toward smarter, more versatile tires.
Manufacturing
Sumitomo Rubber's headquarters and main research center are located in Kobe, in Hyogo Prefecture, Japan, where the Tire Technical Center is supported by test tracks in Mimasaka, Asahikawa and Nayoro. Production is mostly spread across Asia: Japan, Indonesia, Thailand, China and Vietnam, complemented by plants in Turkey and Slovenia for Europe, as well as Ladysmith (South Africa) for the Dunlop, Sumitomo and Falken brands. In North America, the Buffalo, New York plant produced Falken tires before closing. In Quebec and Canada, the group does not own a plant; Sumitomo, Falken and Dunlop tires are imported and distributed through wholesaler and retailer networks.
Reputation
Tires from the Sumitomo group enjoy a reputation for strong value for the money. The Sumitomo brand is seen as an affordable, reliable option, while Falken has established itself as the group's best-selling brand in the United States, popular with performance and off-road enthusiasts. Dunlop, now under SRI in North America, brings a premium heritage. For Quebec, relevance depends on the product: the winter lines (Sumitomo Ice Edge) and 3PMSF-certified all-terrain tires (Falken Wildpeak A/T3W, Encounter AT) meet the winter-tire requirement in effect from December 1 to March 15, whereas high-performance summer tires (HTR Z III, Azenis FK510) are not suited to the cold. Availability is good across Canada through distribution networks.
