The Effect of Stabilizer Ply Geometry on Rolling Resistance and Cornering Force Properties

Many tire construction parameters influence rolling resistance and cornering force properties. This paper concentrates on the influence of the stabilizer ply geometry of radial passenger car tires.

Using a designed experiment, the construction parameters studied were: the width of the stabilizer plies relative to the tread arc width, the crown angle of the stabilizer plies and the amount of rubber gauge above and below the stabilizer ply edges.

Results indicate a strong relationship exists between these construction parameters and rolling resistance and cornering force properties.
