Patent ID: 11912067

Abstract:
In a first aspect, the present invention is directed to a tire comprising a belt portion and a tread portion radially outward of the belt portion, wherein the tread portion comprises a radially outer tread layer for contacting the road when driving and a radially inner tread layer arranged between the radially outer tread layer and the belt portion, wherein the radially outer tread layer comprises a first rubber composition having a first shear storage modulus G′1 and the radially inner tread layer comprises a second rubber composition having a second shear storage modulus G′2, wherein the second shear storage modulus G′2 is between 3 MPa and 9 MPa higher than the first shear storage modulus G′1, and wherein the first shear storage modulus G′1 ranges from 1 MPa to 3 MPa and the second shear storage modulus G′2 ranges from 4 MPa to 12 MPa.
