Tire treads having one or more repeating pitches, each repeating pitch comprising individual pitches having tread blocks with sipes formed therein and each pitch having a pitch length of between 15 mm and 35 mm. Such treads may also have a weighted average sipe density Dw of between 10 mm−1 and 37 mm−1, which is determined through the disclosed Eq. 2 below. The tread blocks are also formed from a rubber composition based upon a diene elastomer, a plasticizing system and a cross-linking system, wherein the rubber composition has a glass transition temperature of between−40° C. and−15° C. and a shear modulus G* measured at 60° C. of between 0.5 MPa and 1.1 MPa. |
