ABSTRACT:
A method for improving uniformity level of a tire having a plurality of projections over a surface thereof includes the steps of measuring a variation in lateral force exerted on a contact are a of the tire while the tire is rotated in at least one of a normal direction and a reverse direction, determining two regions at a tire surface, one region including at least one position where the lateral force variation becomes maximum and the other region including at least one position where the lateral force variation becomes minimum based on the measurement result, and scouring over the determined two regions on at least one of the projections for each half part of the tire surface divided by the center line thereof, which satisfies the following conditions: 1) located on the side of the tire surface corresponding to a first direction in which the lateral force varies, and 2) located neither on a center line of a tire tread nor most outwardly with respect to the center line of the tire tread. According to this method, a lateral force variation of the tire can be reduced more effectively than according to the conventional method almost without changing a radial force variation of the tire.
