The invention discloses a tire with an asymmetric tread pattern structure, which comprises a tread, and the tread is divided into an inner side tire shoulder circumferential pattern rib, a central circumferential pattern rib and an outer side tire shoulder circumferential pattern rib by circumferential main grooves; semicircular three-dimensional silencing spherical grooves are symmetrically formed in the groove walls of the two sides of the circumferential main groove, and oblique straight Y-shaped thin grooves are formed in the first center circumferential pattern rib in the circumferential direction. Inclined Y-shaped thin grooves are formed in the second central circumferential pattern ribs in the circumferential direction; zigzag Y-shaped thin grooves are formed in the third central circumferential pattern rib in the circumferential direction; semi-closed discontinuous inclined straight wide grooves and closed discontinuous inclined straight wide grooves are alternately formed in the inner side tire shoulder circumferential pattern ribs in the circumferential direction; and skew grooves are formed in the circumferential pattern ribs of the outer tire shoulder in the circumferential direction. According to the invention, excellent dry and wet land controllability and good riding comfort can be provided on expressways or common urban pavements, and meanwhile, low driving noise and rolling resistance are achieved.
