Influence of Tire Design Parameters onTire Force and Moment Characteristics

A comprehensive cornering and braking tire test program performed on 380 tires under uniform and strictly controlled conditions resulted in 13 performance characteristics measured at 4 to 6 different loads for each tire. All performance characteristics (more than 25,000) together with tire design and construction information were organized in a computer program that would quickly extract, correlate, and display any data of interest. As examples of the capabilities of the program, the gross effects of wheel diameter, aspect ratio, cord and belt material, and tire construction on linear and non-linear tire cornering and braking characteristics are identified.
