REPORT ORGANIZATION

Chapter 2 provides context and background on the passenger tire’s development, use, and regulation. Chapter 3 examines tire rolling resistance and its effect on motor vehicle fuel economy. It examines the sources of rolling resistance, methods for testing and measuring rolling resistance, and the range and variability in rolling resistance among new passenger tires. The effects of incremental changes in rolling resistance on motor vehicle fuel economy and consumption are also calculated. Chapter 4 examines relationships among rolling resistance, tire wear life, and traction, including the latter’s bearing on motor vehicle safety. Chapter 5 examines and estimates the effects of lower rolling resistance on consumer expenditures on fuel and tires. The study’s key findings, conclusions, and recommendations are presented in Chapter 6.
