Tire Uniformity and Correlation to Vehicle Ride 710086
Tire uniformity grading machines have become an indispensable tool used by all original equipment tire producers for screening tires to acceptable levels for automobile manufacturers. However,so many machines and procedures have been used by tire manufacturers in the past that correlating tire uniformity levels from various sources and determining the effect of variations on the ride quality of passenger vehicles have been been difficult.
Logical follow-up ride evaluations of vehicles have been conducted in comprehensive programs to further investigate the correlation of the various nonuniformity parameters and their individual and compound effects upon ride quality. Investigations are also being conducted to determine correlations of high-speed tire uniformity to low speed and vehicle ride. These and other efforts are directed toward an eventual development of a mathematical description of tire-vehicle behavior.
