A heavy vehicle tire tread that contains a rubber component and a reinforcing filler that includes silica and a second filler. A first and second vulcanization accelerator are used together with sulfur and a silane coupling agent in the tire tread, wherein the 300% modulus of the tire tread is 8 MPa or more. The silane coupling agent, sulfur and total reinforcing filler content in the tire tread composition are present in a ratio range of 1:0.4:0.4 to 1:1.4:1.4.
