Tire tread having asymmetric chamfering

A pneumatic tire comprising:

• a tread having a set of first inwardly disposed blocks and a set of first outwardly disposed blocks disposed in the positive y-direction relative to an equatorial plane, the first inwardly disposed blocks and first outwardly disposed blocks defined at least in part by a top surface, a plurality of circumferentially extending grooves, and a plurality of first laterally extending grooves, the first laterally extending grooves defining leading edges and trailing edges of the first inwardly disposed blocks and first outwardly disposed blocks;
• the tread having a set of second inwardly disposed blocks and a set of second outwardly disposed blocks disposed in the negative y-direction relative to an equatorial plane, the second inwardly disposed blocks and second outwardly disposed blocks defined at least in part by a top surface, a plurality of circumferentially extending grooves, and a plurality of second laterally extending grooves, the second laterally extending grooves defining leading edges and trailing edges of the second inwardly disposed blocks and second outwardly disposed blocks;
• first chamfers located between the leading edges and top surfaces of a plurality of the first inwardly disposed blocks and first outwardly disposed blocks, and wherein the boundaries between the trailing edges and top surfaces of the first inwardly disposed blocks and first outwardly disposed blocks are substantially unchamfered;
• second chamfers located between the trailing edges and top surfaces of a plurality of the second inwardly disposed blocks and second outwardly disposed blocks, and wherein the boundaries between the leading edges and top surfaces of the second inwardly disposed blocks and second outwardly disposed blocks are substantially unchamfered.
