Pneumatic tire having asymmetric tread pattern

摘要

In a pneumatic tire having an asymmetric tread pattern in witch ribs continuing in a tire circumferential direction are disposed on a tread surface at a shoulder end portion on the outer side of a vehicle when the tire is fitted to the vehicle, and block lines each comprising a plurality of blocks are disposed at a shoulder end portion on the inner side of the vehicle, wherein sub-grooves extending in a tire width-wise direction while forming right and left pairs are disposed on the portion of the tire more inward than the ribs at a predetermined pitch in the tire circumferential direction and in a herringbone pattern widening in a direction opposite to a rotating direction of the tire, the apexes of the herringbone patterns are positioned on the outer side of the tire with respect to a tire equator line, and pairs of the right and left sub-grooves are made mutually discontinuous at the apexes.
