<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire for a heavy load which has good durability.SOLUTION: In this tire 2, difference (L2-P) between a radial-direction height L2 from a base line BL to the outside edge 58 of the hard apex 36 of a bead 10 and a radial-direction height P from the base line BL to a first edge 56a of a filler 22 is 8 mm or more. Difference (P-N) between the height P and a radial-direction height N from the base line BL to an edge 46 of the folding part 44 of a carcass ply 40 is -15 mm to 15 mm. Difference (N-O) between the height N and a radial-direction height O from the base line BL to a second edge 56b of the filler 22 is 8 mm to 16 mm. The ratio of the height N to the cross section height in the tire 2 is 0.25 to 0.32.</p> |
