Patent attributes
The present invention is directed to a pneumatic tire comprising a ground contacting tread, the tread comprising a rubber composition comprisingfrom 30 to 70 parts by weight, per 100 parts by weight of s first elastomer (phr) having a glass transition temperature Tg ranging from about −40° C. to about −10° C. and a solubility parameter ranging from about 4.1 MPa1/2 to about 4.5 MPa1/2;from 70 to 30 phr of a second elastomer having a Tg ranging from about −105° C. to about −30° C. and a solubility parameter ranging from about 3.7 MPa1/2 to about 4.1 MPa1/2;from 1 to 40 phr of a first plasticizer having a solubility parameter ranging from 3.4 MPa1/2 to 3.8 MPa1/2;from 1 to 20 phr of a second plasticizer having a solubility parameter ranging from 4.3 MPa1/2 to 4.7 MPa1/2; andfrom 30 to 150 phr of silica.
