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 with a noise damper has a noise damper made of porous resin foam and arranged on a tread inner surface. The noise damper is formed by a single annular body extending continuously in a tire circumferential direction. The noise damper has a core density in a range of from 35 to 65 kg/m3 and an overall density in a range of from 50 to 105 kg/m3. A maximum height of the noise damper from the tread inner surface is in a range of from 12 to 30 mm.

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 pneumatic tire can have a tread portion. A sponge-like sound absorbing member can be attached to an inner surface of the tread portion. The sound absorbing member can have an outer peripheral surface facing outward in a tire radial direction. A plurality of grooves, and a plurality of land portions separated from each other by the plurality of grooves, can be formed in the outer peripheral surface. Each of the plurality of grooves can have an opening width at the outer peripheral surface larger than a groove bottom width of the groove in a cross-section thereof perpendicular to a longitudinal direction of the groove.

Abstract: The present invention provides a pneumatic tire including a sealant layer that has excellent tear resistance despite its being formed of a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire. Included is a pneumatic tire including an innerliner and a sealant layer located radially inside the innerliner, the sealant layer including a first sealant layer and a second sealant layer stacked in that order from the innerliner, the first sealant layer including a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire, the second sealant layer including a generally string-shaped sealant provided continuously and spirally along the first sealant layer, the sealant of the first sealant layer and the sealant of the second sealant layer extending in directions crossing each other.
