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.$GR (n) and R/L.sup.2.sub.SGR (n) which represent the amount of material removal on the first and second shoulders regions, respectively, of each increment I(n) necessary to simultaneously correct excessive radial and lateral force variations. Material is then removed for the first and second shoulder regions of each increment I(n) according to the value of the corresponding first radial/lateral grind component R/L.sup.1.sub.$GR (n) and the value of the corresponding second radial/lateral grind component R/L.sup.2.sub.SGR (n), respectively.
