Research Methodology Tire Production TechSci Research has mapped production capacities of almost all tire manufacturing facilities in Indonesia, with the help of a series of primary research surveys of all the major tire manufacturing companies in the country, followed by validation through secondary sources such as company annual reports and industry associations data. TechSci Research has been successful in identifying the production capacities of each tire plant as well as their respective plant locations, establishment dates and type of tires manufactured in the country. Vehicle Production, Sales and Fleet Size Data points included in the report for analysis of Indonesia commercial vehicle tire market are historical, current and forecast figures for vehicle production, sales and fleet size. Data for vehicle sales and fleet size has been extracted through various secondary sources and credible data portals. TechSci Research has also maintained a database for vehicle sales and fleet size for two-wheelers, which is regularly updated through various primary research surveys and secondary sources such as tire associations and government publications. Tire Demand OEMTireSales OEM tire demand has been calculated by multiplying the average number of tires per vehicle to the total number of vehicles produced. For example, for light duty truck segment, the average number of tires is considered to be 5 and for medium/heavy duty truck, the average number of tires is 7. 11 Automotive © TechSci Research 11
