Abstract: A method for simultaneously correcting excessive radial force variations and excessive lateral force variations in a pneumatic tire is provided. The method includes the steps of indexing the tire tread into a series of circumferential increments I(n), and obtaining a series of radial force measurements corresponding to these increments and a series of lateral force measurements corresponding to these increments. A radial grind component R.sub.$GR (n), a first lateral grind component L.sup.1.sub.$GR (n), and a second lateral grind component L.sup.2.sub.$GR (n) are generated for each of the increments I(n). These grind components represent the amount of material removal necessary to correct for either excessive radial force variations or excessive lateral force variations in the tire. The grind components R.sub.$GR (n), L.sup.1.sub.$GR (n), and L.sup.2.sub.$GR (n) are used to generate first and second radial/lateral grind components R/L.sup.1.sub.$GR (n) and R/L.sup.2.sub.

Abstract: A method is provided for correcting excessive lateral force variations in a pneumatic tire. The method includes the steps of indexing the tire tread into a series of circumferential increments; and obtaining a series of lateral force measurements corresponding to this series of circumferential increments. The maximum value max(1) of the lateral force measurements in a first direction and the maximum value max(2) of the lateral force measurements in a second opposite direction are then determined. This determination is followed by a comparison of each of the lateral force measurements with the max(2) value to determine if it exceeds an acceptable deviation and an independent comparison of each of the lateral force measurements with the max(1) value to determine if it exceeds the acceptable deviation. The acceptable deviation may be a preset constant value.
