发明名称 TIRE TREAD HAVING ASYMMETRIC CHAMFERING
摘要 A pneumatic tire having an asymmetrically chamfered tread that promotes desired plysteer residual aligning torque and/or plysteer residual cornering force. The tire comprises a tread having a set of first blocks on a first side of an equatorial plane, and a set of second blocks on a second side of the equatorial plane. The first and second blocks are defined at least in part by a top surface, one or more circumferentially extending grooves, and a plurality of laterally extending grooves. The laterally extending grooves define leading edges and trailing edges of the blocks. The boundaries between the leading edges and top surfaces of a plurality of the first blocks, and between the trailing edges and top surfaces of a plurality of the second block, are chamfered. The boundaries between the trailing edges and top surfaces of the first blocks, and between the boundaries between the leading edges and top surfaces of the second blocks, are substantially unchamfered.
