    Abstract: A pneumatic tire of the present invention includes a tire inner cavity 1B and a porous sound damper 10. The sound damper 10 is an annular body extending in a tire circumferential direction and is not adhered to a surface of the tire inner cavity 1B. An average thickness T (mm) of the sound damper 10 and an inner cavity surface radius R (mm) satisfy the following formula (1). An average circumferential length L (mm) in a circumferential direction of the sound damper 10 in a state where the sound damper 10 is removed from the pneumatic tire, and an inner cavity surface circumferential length C (mm), satisfy the following formulas (2) and (3). 0.04 ≤ T / R ≤ 0 .18 ( 1 ) 1.02 - 1.1 × T / R ≤ L / C ≤ 0 . 9 ⁢ 5 + 1.4 × T / R ( 2 ) L / C ≤ 1 . 1 ( 3 )

    Abstract: A pneumatic tire is provided with a noise damper made of a sponge material attached to a radially inner surface of the tread portion. The noise damper has protruding portions protruding from a radially inner surface of a band-shaped base portion. The protruding portions extend from one edge to the other edge of the base portion in the widthwise direction, and arranged at intervals in the tire circumferential direction. In a cross section of the tire parallel with the tire equatorial plane, the radially inner surface of each of the protruding portions includes a flat portion, and the radially inner surface of the base portion includes an arc portion parallel with the inner surface of the tread portion.

    Abstract: An information processing system and an information processing method that can allow the circumferential length of the tire inner cavity surface of a pneumatic tire to be easily identified. The information processing system can include: a first acquisition processing unit configured to acquire shape identification information used to identify a shape of a pneumatic tire; a second acquisition processing unit configured to acquire circumferential length information corresponding to a circumferential length of a tire inner cavity surface of the pneumatic tire on the basis of the shape identification information acquired by the first acquisition processing unit; and an output processing unit configured to output the circumferential length information acquired by the second acquisition processing unit.

    Abstract: A runflat tire includes a tire body, a carcass extending from a tread portion through sidewall portions of the tire body to bead cores in bead portions of the tire body, and sidewall-reinforcing rubber layers having cross-sectional crescent shapes and positioned on inner sides of the carcass along the sidewall portions, respectively. The tire body has height Ha in range of 8˜17 mm where the height Ha is measured from a rim line of the tire body to inner edge of an innermost dimple/fin row of the tire body in radial direction of the tire body, the innermost row is formed in dimple/fin forming region including one or more dimple/fin rows having dimple/fin portions arrayed in circumferential direction of the tire body, and the dimple/fin forming region is formed on external surface of a sidewall portion on outer side of the rim line in the radial direction.
