Abstract
Lateral force variations of a tire are reduced by detecting the variations in the conicity component of the lateral force with respect to the rotation angle in both forward and rearward rotational senses. The algebraic sum of the lateral force exerted by the tire parallel its own axis on a load wheel or road surface at successive angular increments of rotation in both rotational senses provide a variant signal which can be used to control grinding means to remove material from the respective tire shoulder regions in amounts and angular locations to reduce the variation of the conicity component and thus the total lateral force variation exerted by the tire in either rotational sense. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
