Founded in 1889 in Birmingham, England, Dunlop focused on manufacturing pneumatic (air-filled) tires, an invention attributed to John Boyd Dunlop, who is often credited with revolutionizing transportation.

Dunlop's early success was driven by the widespread adoption of its pneumatic tires, particularly for bicycles and, later, automobiles. By the early 20th century, the company had become a leading manufacturer of tires and other rubber products, expanding its operations across Europe, the United States, and Australia. Dunlop was also instrumental in supplying tires during the rapid growth of the automotive and aviation industries. Dunlop diversified its offerings to include products such as industrial rubber goods, conveyor belts, sports equipment, and footwear.

Its Dunlop Sports division, launched in the early 20th century, became famous for producing tennis rackets, golf balls, and other sporting goods, further strengthening its brand.

By the 1960s and 1970s, rising costs, outdated manufacturing methods, and global competition placed significant financial strain on the company. Efforts to diversify into other industries were not enough to stabilize its fortunes.

In 1981, the Dunlop Rubber Company was acquired by BTR plc, a British conglomerate, marking the end of its independence. The Dunlop name continued to live on through its various divisions, which were sold off to different companies over time. The Dunlop tire brand is now split between Goodyear Tire & Rubber Company in North America and Sumitomo Rubber Industries in other markets.

Dunlop Sports was acquired by Sumitomo Rubber Industries in 2017.. The Dunlop footwear division, known for its rubber boots and safety shoes, remains a trusted name in industrial and outdoor markets.
