PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving durability while keeping favorable controllability, stability and ride comfort, in the pneumatic tire including carcass layers separated in a tread. SOLUTION: The carcass layers 4 separated in the tread portion 1 are laid between a pair of beads 3, 3, and a belt layer 6 is disposed at an outer peripheral side of the carcass layer 4 in the tread 1. Adhesive rubber layers 7 are interposed between the belt layer 6 and each divided piece 4A of the carcass layers 4. The JIS-A hardness of the adhesive rubber layer 7 is set to be larger than the JIS-A hardness of the rubber of the carcass layer 4, and the JIS-A hardness of the adhesive rubber layer 7 is set to be smaller than the JIS-A hardness of the rubber of the belt layer 6.
