An apparatus includes a grid circuit having dimensions corresponding to an inner surface of a tire, a computational device coupled to the grid circuit, and a wireless communications device coupled to the computational device. The wireless communications device is configured to transmit detection of damage to the grid circuit. A computer-implemented method includes monitoring a grid circuit positioned in a tire to detect damage to conductors of the grid circuit, detecting damage to at least one of the conductors of the grid circuit, and transmitting information about the damage to a computer of a vehicle. A computer-implemented method includes receiving, from a computational device coupled to a grid circuit in a tire, information about damage to the grid circuit and outputting an indication that the tire is damaged.

A hand-held device for obtaining a three-dimensional topological surface profile of a tyre, the device comprising: a base comprising an aperture; a light source arranged in use to generate an elongate pattern of light, and to project said pattern through the aperture onto a rolling surface of the tyre; a detector arranged to image a region of the rolling surface of the tyre; a plurality of pairs of guide wheels mounted on respective axles mounted on the base, wherein the guide wheels on adjacent axles are linked by gears; and a rotary encoder arranged to generate a signal corresponding to rotation of an axle.

A decision support system initially determines in response to the creation of a customer ticket a customer's driving style in accordance with user responses and input regarding driving habits and preferences, and calculates a driving style algorithm. The system compares the driving style algorithm to car tire profiles and determines which tires are best suited to the customer's driving style algorithm. Upon said determination, the selected car tires are presented to the customer for final selection in a comprehensive service platform environment for creating, forwarding, performing, and completing customer tickets amongst front end devices comprising a computer kiosk and a customer's mobile device, and a back end device comprising an employee's mobile device. Tickets created via a front end device are forwarded for performance to the back end device, wherein upon completion of service the ticket is finalized and forwarded back to a front end device for review and payment.

A road surface state determination device includes a tire-side device and a vehicle-body-side system. The tire-side device is attached to each of a plurality of tires included in a vehicle. The vehicle-body-side system is included in a body of the vehicle. The tire-side device may output a detection signal corresponding to a magnitude of vibration applied to the tire. The tire-side device may extract data items of a road surface state indicative of the vibration of the tire during one rotation of the tire from the detection signal. The tire-side device may generate road surface data. The tire-side device may transmit the road surface data. The vehicle-body-side system may receive the road surface data. The vehicle-body-side system may determine the road surface state based on the road surface data.

A pneumatic tire includes a tread portion that is provided with two block rows formed of three circumferential grooves and a plurality of first transverse grooves. A block that configures the block rows has a hexagonal shape, and has a diagonal extension line passing through a pair of vertices positioned in the central portion in the tire-circumferential direction, the diagonal extension line overlapping, in the tire-circumferential direction, the first transverse groove of the adjacent block rows. The block has a first sipe that is terminated within a block extending in the tire-width direction. The first sipe is provided at a position shifted from the diagonal extension line in the tire-circumferential direction and in a region interposed between planes that are formed by extending, in a direction in which the first transverse groove extends, from a pair of groove wall surfaces of the first transverse groove of the adjacent block rows.
