PROBLEM TO BE SOLVED: To provide a tire allowing compatibly achieving of cutting resistance and riding comfort. SOLUTION: This pneumatic tire 10 includes a bead part 1, a carcass 5 made by twisting a plurality of cords and including a folded part 5a folded back to the tread width direction outside in the bead part 1 and a belt layer 7 arranged at the tire radial direction outside of the carcass 5. The carcass 5 includes a first region 51 including an outside end of the tire radial direction of the carcass 5 and a second region 52 continuous to the first region 51 in the folded part 5a. An inside end 51a of the first region 51 is located in the range of≥40% and≤60% of a tire height H1 in relation to the tire height H1 to be a height from a bead toe 1a at the tire radial direction inside of the bead part 1 up to an end part 7a at the tire radial direction outside of a tread part 4. An outside end 51b of the first region 51 is located in the vicinity of a tread width direction end part of a belt layer 7. The twisting number of cords in the first region 51 is larger than that in the second region 52. COPYRIGHT: (C)2011,JPO&INPIT
