This article examines the internal and external factors that contributed to the decline of Dunlop. For much of its history Dunlop operated in a protected home market or instigated strategies to restrict competition. This enabled Dunlop to dominate the British tyre industry. The complacency and inertia of management was exposed by a number of external Jolts that produced radical environmental changes. Management failed to develop appropriate strategies which led to large losses in an industry suffering from overcapacity. Plant closures and the divestment of the European tyre operations were implemented to reduce company debt. This turnaround strategy proved to be a temporary respite as Dunlop was acquired by BTR.
