PURPOSE:To reduce vibration noises while maintaining the durability, the wear resistance, the lower heat generating property and the like by arranging a tread rubber applied on the circumferential surface of a base band made up of a double layer of a cap rubber and a base rubber comprising a rubber specified composition. CONSTITUTION:A solid tire 1 has a tread rubber 3 applied on the circumferential surface of a base band 2. In this case, the tread rubber 3 is made up of a double layer of a cap rubber 4 arranged on the side of a grounded surface (c) and a base rubber 5 arranged through an adhesion layer 6 adjacent to the base band 2 thereunder. A rubber composition used for the base rubber 5 is mainly made up of a butyl based rubber as rubber component. The butyl-based rubber includes a butyl rubber, a chlorinated butyl rubber and a brominated butyl rubber. To be mainly made up of the butyl-based rubber means that the composition is blended with it at a rate of 30wt.pts., preferably 40-70wt.pts. as rubber component. |
