  • Patent number: 11505010
    Abstract: A pneumatic tires includes a tread, a pair of sidewalls, and a pair of bead portions that are arranged at intervals wider than a rim width of a corresponding regular rim in a non-rim-assembled state. Each of the pair of the bead portions includes a bead base at an inner diameter side end, a bead heel, and a bead back surface extending from an outer diameter side end of the bead heel, to the outer diameter side. In the non-rim-assembled state, the bead back surface is formed with a recess that is recessed inward in the width direction. In a rim-assembled state, the bead back surface is in close contact with substantially the entire surface of a radial portion of a rim flange of a regular rim.

  • Patent number: 11491995
    Abstract: An arithmetic model generation system includes a sensor information acquisition unit, a tire force calculator, and an arithmetic model update unit. The sensor information acquisition unit acquires acceleration of a tire. The tire force calculator includes an arithmetic model for calculating tire force F based on the acceleration, and calculates the tire force F by inputting the acceleration acquired by the sensor information acquisition unit. The arithmetic model update unit compares tire axial force measured by the tire and the tire force F calculated by the tire force calculator, and updates the arithmetic model.

  • Publication number: 20220339970
    Abstract: A pneumatic tire has a sidewall that extends in a tire radial direction. The the sidewall has an insignia which protrudes toward an exterior in a tire axial direction. The insignia has a strip-like body, an endless-loop-like outline which encompasses the body, and a bridge which is arranged toward an exterior from the endless loop of the outline and which causes a mutually separated pair of the outlines to be mutually connected. Heights by which the body and the outline protrude relative to a reference surface which is an exterior surface in a region peripheral to the insignia are mutually different. A height by which the bridge protrudes relative to the reference surface is less than each of the protruding heights of the body and the outline.

  • Patent number: 11459428
    Abstract: A method for producing a rubber wet master batch is disclosed including: producing a carbon black-containing rubber latex solution by mixing carbon black, a dispersion solvent and a rubber latex solution; producing a carbon black-containing rubber coagulum by coagulating the thus-obtained carbon black-containing rubber latex solution; and producing a rubber wet master batch by dehydrating and drying the thus-obtained carbon black-containing rubber coagulum. With respect to this method for producing a rubber wet master batch, the carbon black satisfies conditions such that: the DBP oil absorption is 105-230 mL/100 g; STSA is 90-205 m2/g; and the value obtained by subtracting the value of STSA from the value of DBP oil absorption is 15 or more. This method for producing a rubber wet master batch enables the achievement of a vulcanized rubber that has wear resistance and low heat generation properties.
