A heavy truck tire tread having a longitudinal direction, a transverse direction, a thickness direction, and a ground-engaging surface, the heavy truck tire tread comprising a series of at least 50 similar tread features repeated along its longitudinal direction, each of the similar tread features comprising: two ducts extending from the ground-engaging surface in the thickness direction, the ducts being apart one from the other and having a duct section area of at least 10 mm 2 and a length of between 50% and 100% of a thickness of the tread; one void being in fluid communication with the two ducts, the void extending substantially parallel to the ground-engaging surface of the tread and at a distance therefrom and having a void section area of at least 10 mm 2 ; and one sipe joining the two ducts and the void, wherein the tread feature is otherwise blind and wherein the heavy truck tire tread is formed at least in part of a rubber composition that is based upon a cross-linkable elastomer composition, the cross-linkable rubber composition comprising, per 100 parts by weight of rubber (phr): at least 75 phr of a first rubber component selected from a polybutadiene rubber (BR), a styrene-butadiene rubber (SBR) or combinations thereof having a Tg of between -80 °C and -110 °C; between 0 phr and 25 phr of a secondary rubber component that is a diene elastomer; at least 40 phr of a plasticizing resin having a Tg of at least 25° C; and a reinforcing filler; the Tg of the first rubber component and of the plasticizing resin being measured by Differential Scanning Calorimetry (DSC) in accordance with ASTM D3418. two ducts extending from the ground-engaging surface in the thickness direction, the ducts being apart one from the other and having a duct section area of at least 10 mm 2 and a length of between 50% and 100% of a thickness of the tread; one void being in fluid communication with the two ducts, the void extending substantially parallel to the ground-engaging surface of the tread and at a distance therefrom and having a void section area of at least 10 mm 2 ; and one sipe joining the two ducts and the void, wherein the tread feature is otherwise blind and wherein the heavy truck tire tread is formed at least in part of a rubber composition that is based upon a cross-linkable elastomer composition, the cross-linkable rubber composition comprising, per 100 parts by weight of rubber (phr): at least 75 phr of a first rubber component selected from a polybutadiene rubber (BR), a styrene-butadiene rubber (SBR) or combinations thereof having a Tg of between -80 °C and -110 °C; between 0 phr and 25 phr of a secondary rubber component that is a diene elastomer; at least 40 phr of a plasticizing resin having a Tg of at least 25° C; and a reinforcing filler; the Tg of the first rubber component and of the plasticizing resin being measured by Differential Scanning Calorimetry (DSC) in accordance with ASTM D3418. at least 75 phr of a first rubber component selected from a polybutadiene rubber (BR), a styrene-butadiene rubber (SBR) or combinations thereof having a Tg of between -80 °C and -110 °C; between 0 phr and 25 phr of a secondary rubber component that is a diene elastomer; at least 40 phr of a plasticizing resin having a Tg of at least 25° C; and a reinforcing filler; the Tg of the first rubber component and of the plasticizing resin being measured by Differential Scanning Calorimetry (DSC) in accordance with ASTM D3418. <EOS>
