<p>PROBLEM TO BE SOLVED: To reduce rolling resistance while supporting inputted load certainly.SOLUTION: In a carcass layer 15, provided are a first carcass ply 19 which extends continuously over a bead part 11, a side wall part 13 and a tread part 12, and a right and left pair of second carcass plies 20 which are laminated over the first carcass ply 19 and are arranged at a right and left pair of side wall parts 13 respectively. Among the second carcass plies 20, at least a part of one edge part 20a positioning at the tire radial direction outside positions at the edge part of a tire width direction H of the tread part 12, and at least a part of the other edge part 20b positioning at the tire radial direction inside positions at the inside of the tire width direction H of the bead core 14.</p> |
