A tire anti-theft system includes a transmitter attached to a tire and configured to transmit tire ID information; a first database configured to store vehicle ID information and tire ID information of a tire mounted on the vehicle; a second database configured to store the tire ID information and tire status information indicating whether or not the tire identified with the tire ID information is stolen tire; and a vehicle control apparatus, in which the vehicle control apparatus includes a reader configured to perform near field communication with the transmitter attached to the tire mounted on a vehicle to be controlled and acquire the tire ID information, and a controller configured to, in a case where the reader acquires the tire ID information, restrict operation of the vehicle to be controlled if information indicating that the tire is stolen tire is stored in association with the tire ID information.

Tire anti-theft system, vehicle control apparatus, and vehicle control method

An information presentation system includes an information presentation apparatus, a transmitter attached to a tire and configured to transmit tire ID information for identifying the tire, and a database configured to store tire ID information of tires which are genuine products, and the information presentation apparatus includes a reader configured to perform near field communication with the transmitter, to acquire the tire ID information transmitted by the transmitter, and a controller configured to cause an information presenter to present information indicating that the tire identified with the tire ID information is a genuine product in a case where the tire ID information is stored in the database, and/or cause the information presenter to present information indicating that the tire identified with the tire ID information is a counterfeit product in a case where the tire ID information is not stored in the database.

There is provided a pneumatic tire having an aspect ratio of not less than 60 and considerably improving run flat durability as compared with the conventional type of the run flat tire, wherein at least one cushion rubber layer having a loss tangent lower than a loss tangent (tan &#x3b4;) of a coating rubber for cords of a carcass ply is arranged between an end portion of a belt and a reinforcing rubber layer in a shoulder region and between mutually adjacent tire constitutional members. And also, when the carcass is comprised of plural plies, at least one ply is separated off in a zone beneath the belt, whereby the ride comfort against vibrations can be more improved.

Rubber composition and pneumatic tire using said rubber composition

A pneumatic tire having an aspect ratio of not less than 60 comprises a radial carcass of one or more plies, a belt, a bead filler rubber and a rubber reinforcing layer of substantially a crescent shape in section extending from a position near to a bead core to a position near to a tread end along an inner surface of an innermost carcass ply, wherein at least one rubber protection sheet being relatively soft is disposed between the bead filler rubber and the carcass ply surrounding it and/or between the rubber reinforcing layer and the carcass ply nearest thereto.

Rubber-steel cord composite and pneumatic tire for passenger cars

There is provided a pneumatic tire having an aspect ratio of not less than 60 and considerably improving run flat durability as compared with the conventional type of the run flat tire, wherein at least one cushion rubber layer having a loss tangent lower than a loss tangent (tan &dgr;) of a coating rubber for cords of a carcass ply is arranged between an end portion of a belt and a reinforcing rubber layer in a shoulder region and between mutually adjacent tire constitutional members. And also, when the carcass is comprised of plural plies, at least one ply is separated off in a zone beneath the belt, whereby the ride comfort against vibrations can be more improved.

Rubber composition for tire treads

Pneumatic safety tire with rubber-organic filament fiber layer

An extruding mechanism for a tubular bag and a method of extruding the contents of a tubular bag are provided, by which a sealing material or the like is extruded and discharged from a tubular bag with an extruding gun for a cartridge container, and which reduces the amount of discarded waste, thereby serving as one solution to environmental problems. The extruding mechanism includes an extruding gun having a holding base, and a stationary holding plate disposed on a front end portion of the holding base. The holding plate is provided with a notched portion opened upward. An extruding rod is equipped at its leading end with a pressing plate. A cylindrical member having a cylinder body is set on the holding base and accommodates the tubular bag and is opened at both ends, and a piston body is inserted into the cylinder body. A head adapter includes a base plate and has an outer surface side located on an inner surface of the stationary holding plate, an inner surface side thereof with which the opening end portions of the cylinder body are brought into contact, and an opening portion. A nozzle body has a discharge hole at its leading end, the nozzle body being attached to the opening portion of the head adapter.

Extruding mechanism for film packs

A pneumatic tire for passenger cars comprises bead cores, a carcass layer, a tread portion, and side wall portions, wherein a rubber reinforcing layer having a crescent-shaped cross-section and at least one sheet of a rubber-filament fiber composite having a thickness measured under a pressure of 20 g/cm,of 0.05 to 2.0 mm which is formed from a rubber component and filaments having a diameter or a maximum cross-sectional dimension of 0.0001 to 0.1 mm and a length of 8 mm or more are disposed in said side wall portions. Reinforcing cords of carcass plies are made of an aliphatic polyamide fiber having a melting point of 250&deg; C. or higher.

Pneumatic tire for passenger cars with sidewall portions having a rubber reinforcing layer and a rubber-filament fiber composite

A pneumatic tire for a passenger car having a pair of bead portions, a toroidal carcass portion extending over both bead portions, at least two belt layers provided in a crown portion of the carcass, a tread portion positioned at an outer peripheral side of the belt layer, and side wall portions provided at the right and left sides of the tread portion, and which further includes a steel cord as a reinforcing material for reinforcing at least one layer of the carcass portion and the belt layer. The steel cord is formed by plying a plurality of filaments each having a strand diameter of 0.125 to 0.275 mm, and has an inflection point on an S&mdash;S curve. A reduction rate of a diameter of the steel cord under a load stress which is one third of breaking strength in comparison with a no load condition is equal to or more than 20%.

Pneumatic tire for passenger cars including specified steel cord

There is disclosed a safety pneumatic tire comprising a tire shell which is equipped with a toroidal carcass extending over a pair of bead portions and also functioning as a reinforcing material for a side wall portion connected to the bead portions and further for a tread portion, and which has a side-reinforcing layer on the internal surface of the side-wall portion; a rim which hermetically seals and supports the bead portions of the tire shell; and closed cell-based elastic foam which is filled in the internal hollow portion encompassed by the tire shell and the rim, wherein the constructional material of the elastic foam is butyl rubber or halogenated butyl rubber. The above safety pneumatic tire is markedly improved in run-flat durability, can reconcile favorable riding comfort chacteristic with the run-flat durability, is minimized in adverse influence upon the tire performances such as rolling resistance, and enables the production of a lightweight pneumatic tire.
