PROBLEM TO BE SOLVED: To provide a solid tire which prevents reduction of durability and also prevents reduction of fuel consumption performance. SOLUTION: The solid tire is provided with a base part 1; and a tread part 2 formed on a surface of the base part 1. The tread part 2 includes a skin layer part 2a and an inner layer part 2b. The inner layer part 2b uses a rubber composition in which 5-80 mass pts of bituminous coal crushed substance is blended relative to 100 mass pts of diene based rubber component. In the rubber composition, carbon black in which a mass ratio of the bituminous coal crushed substance relative to carbon black (bituminous coal crushed substance/carbon black) becomes 1/20-20/1, is further blended.
