<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of concurrently satisfying maneuvering stability and riding comfort in a high order. <P>SOLUTION: The pneumatic tire 10 includes a rubber sheet layer 30 covering a bead filler 24. The rubber sheet layer 30 includes: an inner rubber sheet layer 30A in contact with the whole region of an inner surface of the bead filler 24 and the inner surface of a bead core 22 in proximity to the bead filler 24; and an outer rubber sheet layer 30B in contact with the whole region of the outer surface of the bead filler 24 and an outer surface of the bead core 22 in proximity to the bead filler 24. The hardness of the bead filler 24 is 50-90 in hardness measured with a durometer of JISK6253 Type A under the atmosphere of 20°C and the hardness of the rubber sheet layer 30 is higher than that of the bead filler 24 by 3 to 10. The thickness T of the rubber sheet layer 30 is 0.5-2.0 mm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
