A pneumatic tire in accordance with the present disclosure comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on a tire internal space side of the first sound damper, and being made of a sponge material; and a communication device retained between the first sound damper and the second sound damper, wherein the second sound damper has a hardness greater than a hardness of the first sound damper.

Pneumatic tire

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.

A tire theft monitoring system includes a transmitter attached to a tire and configured to transmit tire ID information, a second database configured to store the vehicle ID information of the vehicle and contact information of an owner of the vehicle in association with each other, and a monitoring apparatus mounted on a vehicle to be monitored, and the monitoring apparatus includes a reader configured to perform near field communication with the transmitter attached to the tire mounted on the vehicle to be monitored, to acquire the tire ID information, and a controller configured to, in a case where the reader cannot acquire the tire ID information, determine that the tire identified with the tire ID information has been stolen and make a notification to contact information stored in the second database in association with vehicle ID information of the vehicle to be monitored.

Tire theft monitoring system, tire theft monitoring apparatus, and tire theft monitoring method

The present invention provides a tire in which generation of partial wear and groove cracks are suppressed. Specifically, the present invention provides a tire having in a tread surface thereof plural circumferential grooves extending in the tire circumferential direction, characterized in that: each of respective circumferential grooves disposed on the outermost side in the tire widthwise direction is designed to have a section in the tire widthwise direction, in which an angle formed by a groove wall on the outer side in the tire widthwise direction, with respect to a straight line tangent to a tread contour at the opening edge on the outer side in the tire widthwise direction of said groove, is larger than an angle formed by a groove wall on the tire equatorial side in the tire widthwise direction, with respect to a straight line tangent to a tread contour at the opening edge on the tire equatorial side in the tire widthwise direction of said groove; and each of said angles is in the range of 90&#xb0; to 100&#xb0; (inclusive of 90&#xb0; and exclusive of 100&#xb0;).
