Cord Load Characteristics In Bias And Belted-Bias Tires, Joseph Walter, George Hall

Dr. Joseph D. Walter

Two improved versions of a recently developed miniature force transducer were used to measure cord loads at the crown, shoulder, and sidewall of bias and belted-bias automobile tires under different testing conditions. As a transducer at a given location passes through the footprint, a “basic shape” for the cord force pattern is generated for straight ahead rolling and cornering. Factors such as wheel load, inflation pressure, obstacle impact, tire speed, rim width, and frictional properties of the tire-drum interface can affect the total force excursion and/or the base line value but do not affect the basic shape of the patterns. …
