Sumitomo Rubber Industries

From Wikipedia, the free encyclopedia

Sumitomo Rubber Industries, Ltd. (住友ゴム工業株式会社, Sumitomo Gomu Kōgyo Kabushiki-gaisha^?) (TYO: 5110) is a tire and rubber company based in Japan. It is part of the Sumitomo Group.

The company traces its origins to 1909, when the Sumitomo Group made an investment in Dunlop Japan, the newly formed Japanese subsidiary of the British company Dunlop Rubber. Over the years Sumitomo and Dunlop developed a close business relationship, and in 1963 the Sumitomo Group acquired control of Dunlop Japan and renamed it Sumitomo Rubber Industries Ltd.

In 1985, when Dunlop Rubber was taken over by BTR plc, the company acquired the automobile tire assets of Dunlop, including the right to use the Dunlop brand on automobile tires. The acquisition did not include the US and Australian businesses, which were separately owned, but in 1986 Sumitomo also acquired the Dunlop Tire Corporation of the US from its management^[1].

In 1997, Sumitomo formed a joint venture with Goodyear Tire and Rubber Company, by which Goodyear and Sumitomo agreed to manufacture tires for each other's markets, including Dunlop branded tires. As part of the agreement, Goodyear acquired 75% interests in Dunlop Tyres, the UK company which Sumitomo had formed, and in Dunlop Tire Corporation. Goodyear and Sumitomo also made investments in each other.^[2]

Today, the company makes tennis rackets, automobile tires, tennis balls, golf balls, and various other rubber products.
