Key takeaways

  • Sumitomo Rubber Industries belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sumitomo Rubber Industries to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sumitomo Rubber Industries from memory before moving on to harder problems.

Reference excerpt

Sumitomo Rubber Industries, Ltd. (住友ゴム工業株式会社, Sumitomo Gomu Kōgyo Kabushiki-gaisha) is a global tire and rubber company based in Japan. It is part of the Sumitomo Group. The company makes a wide range of rubber based products, including automobile tires, golf balls, and tennis balls. Sumitomo tire brands include Dunlop and Falken. Sumitomo also manufactures and sells sport equipment under the Dunlop Sport, Srixon, and Cleveland Golf brands.

History 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. 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. On 14 February 2014, Goodyear announced its intention to dissolve its partnership with Sumitomo due to alleged "anticompetitive conduct". On June 4, 2015, Goodyear announced the end of its joint venture with SRI, effective end of year 2015. The brand Dunlop will be shared between the 2 companies:

in North America, Goodyear will control the Dunlop brand for replacement tires and for new cars made by non-Japanese auto makers. Sumitomo Rubber will hold rights to the Dunlop brand for new cars made by Japanese auto makers, as well as for motorcycles; in most parts of Europe (including Dunlop's home country Ireland), Goodyear will control the Dunlop brand; and in Japan, Sumitomo Rubber will retain rights to the Dunlop brand. In December 2013 Sumitomo Rubber Industries acquired Apollo Tyres South Africa (Pty) Ltd from Apollo Tyres, which owned the Dunlop tyre brand in South Africa, as part of its strategic global development plans. It subsequently renamed the company Sumitomo Rubber South Africa (Pty) Ltd. Sumitomo Rubber South Africa manufactures the Dunlop, Sumitomo and Falken passenger car tyre brands in Ladysmith, KwaZulu-Natal. The Ladysmith plant began to produce Dunlop truck and bus radial tyres in July 2018, following the second of two large investments by Sumitomo Rubber Industries to upgrade and modernise the plant. Dunlop truck and bus radial tyres produced in Ladysmith will be sold in the South African market and will also be exported to several African states from 2019.

Falken Tire The Falken Tire brand was launched by Sumitomo in Japan in 1983, and was introduced in North America two years later. In January 2016, after the dissolution of the partnership with Goodyear, the Sumitomo Rubber USA factory in Tonawanda, New York began to produce Falken Tire-branded tires. The Falken brand is considered a low-price brand tire in the North American market, rated as a Tier 3 tire by those in the industry.

SRI Sports Limited SRI Sports Limited is the subsidiary of Sumitomo that specializes in sports equipment, with the main focus being tennis and golf. SRI Sports owns Srixon, XXIO, Cleveland Golf, its subsidiary, Never Compromise, as well as rights to the Dunlop name in most parts of the world. Srixon produces tennis balls, golf balls, golf clubs, and a full range of golfing accessories. It holds several professional golfers under endorsement deals including Hideki Matsuyama, Shane Lowry, Graeme McDowell, Keegan Bradley and Brooks Koepka. Cleveland Golf also makes a full range of golf equipment, and has endorsement deals with Vijay Singh and Boo Weekley among others. Following the acquisition of Cleveland Golf, SRI Sports announced their intention to consolidate its operations, with Cleveland overseeing marketing and distribution across North America, with Srixon doing the same in Europe and Australia, and Dunlop taking over in Asia. In 2018 Dunlop entered into a partnership with Tennis Australia and became the official ball of the Australian Open, in a multi-year deal.

Worked examples

Example 1 — a first encounter with Sumitomo Rubber Industries

Start with the simplest possible case. Write down what Sumitomo Rubber Industries claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sumitomo Rubber Industries before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sumitomo Rubber Industries ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sumitomo Rubber Industries

In research
Sumitomo Rubber Industries appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sumitomo Rubber Industries in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sumitomo Rubber Industries is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970s initial public offerings, Automotive companies of Japan, Companies listed on the Osaka Exchange, so understanding it makes those chapters shorter.
In everyday life
Look for Sumitomo Rubber Industries outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
