First, John Dunlop made a tire which consist a tube mounted on a spoked rim. In the beginning, solid rubber tires were used mostly for bicycles and horse-driven carts. Tire has gone through many stages of evolution, since it was developed first time about 100 years ago. A DMAIC methodology was established that can play a key role for reducing defects in the tire-manufacturing process in India. The process capability index ( C p) value was enhanced from 1.65 to 2.95 and the process performance capability index ( C pk) value was enhanced from 0.94 to 2.66. Utilizing DMAIC methodology, the standard deviation was decreased from 2.17 to 1.69. The process control charts were used for systematic observation and control the process. This step was followed by the analysis and improvement steps, where the six-sigma quality tools such as cause–effect diagram, statistical process control, and substantial analysis of existing system were implemented for root cause identification and reduction in process variation. The subsequent step constitutes of gathering the specification data of existing tire bead. This six-sigma DMAIC research was initiated by problem identification through voice of customer in the define step. In the current research, the DMAIC method was used for decreasing the process variations of bead splice causing wastage of material. This method helps to trim down the wastes and generating the potential ways of improvement in the process as well as service industries. To overcome these barriers, the six-sigma define–measure–analyze–improve–control (DMAIC) method is most popular and useful. Globalization, advancement of technologies, and increment in the demand of the customer change the way of doing business in the companies.
