A tire holding apparatus is provided with a first support part for supporting a tire, a second support part for supporting the tire, and an air supply and removal part for supplying and removing air from the inside of the tire. The second support part has a protrusion that protrudes toward the first support part. The air supply and removal part has a first flow path for allowing air to flow, a second flow path for allowing air to flow from an opening formed at the leading end of the protrusion to the inside of the tire, and a collection part that is attached to the opening and collects foreign matter that has been mixed into the second flow path from the inside of the tire.

A sensor device for tire inspection is provided. The sensor device is configured for removable placement upon or near the surface of the tire. The sensor device includes one or more tire inspection sensors configured to inspect e.g., the condition of one or more components or portions of the tire. The sensor device also includes one or more proximity sensors configured to detect whether the sensor device is in proper proximity of the tire such that the one or more tire inspection sensors can operate correctly.

A tire inspection method includes: capturing a transmission image of a tire including a steel chafer at a bead portion; generating an image at an inspection device from the captured image of a full revolution of the tire with the steel chafer portions extracted using a spatial filter generated in accordance with an incline of the wires of the steel chafer; detecting a locus of a front side edge and a back side edge of the steel chafer; generating an image from the captured image with the steel chafer portions removed; detecting a locus of a turned-up edge of a carcass from this image; and determining at the inspection device the position of the carcass to be appropriate or not on the basis of the locus of the turned-up edge of the carcass.

A method of measuring the inflation pressure of tires (Ppneu) on a vehicle in movement, comprising at least the following steps, during which: a) one measures the pressure exerted on at least one sensor of pressure (1) secured to the ground, in the rolling zone of the tire, by a tire (3) rolling over said sensor (1), b) one measures the time (t) during which the tire (3) rolls over said sensor (1), c) one establishes, during the movement of the tire (3) over said sensor (1), a curve representing the distribution of the forces (Psol) exerted by the tire (3) as a function of the time (t), d) one determines the inflation pressure (Ppneu) of the tire (3) with the aid of a computer, with an algorithmic programming and/or fuzzy logic.

The method comprises at least the following step: e) during step d), the model used takes into account two other parameters, namely, the length (Lpneu) of the tire (3) tread in contact with said sensor (1) during the measurement performed in step b), and the shape (Forme) of the curve obtained in step c).

A tire testing device includes a carriage configured to rotatably hold a test wheel provided with a test tire and being capable of travelling on a base along a road surface in a state where the test wheel is made to contact the road surface, and a driving system configured to drive the test wheel and the carriage. The driving system includes a carriage driving part configured to drive the carriage with respect to the road surface in a predetermined speed, a test wheel driving part configured to drive the test wheel in a rotating speed corresponding to the predetermined speed, a driving part configured to generate power to be used to drive the carriage and the test wheel, and a power distributing part configured to distribute power generated by the driving part to the carriage driving part and the test wheel driving part.

A testing machine for tires has a base, a first slider, a second slider and a brake arm. The tire testing machine can test the tire's tread and bead lip at the same time, and then obtain the test data of the tire's plunger requirements and the ability to remove the lip, which can effectively reduce the time and labor for the tire's replacement and transfer cost, thereby improving the test efficiency of the tire, and helping to improve the accuracy of test data integration and analysis, and through the design feature of one machine, it can also reduce the cost of machine purchase and the doubt about placing the machine space, which have substantial effects of practicality and convenience.

A tire testing device having a rotary drive unit that rotationally drives a tire; a load drum that has an outer peripheral surface that can come into contact with the tire being rotationally driven; a drum support mechanism that supports the load drum and relatively moves the load drum such that the tire and the outer peripheral surface of the load drum come into contact and separate; a shape sensor that detects a surface shape of the tire being rotationally driven; a drive control unit that controls the operation of the rotary drive unit, the drum support mechanism, and the shape sensor; a registration unit that stores information related to the tire test; and an input reception unit that receives, and registers, in the registration unit, information related to the tire test entered by a user prior to the tire test being conducted.

A tire testing apparatus for testing a tire comprises a loading means for the tire (17), a measuring head (20, 22, 24) which is movable relative to the tire (17), and lower bearing elements (7) on which the tire (17) can be positioned in vertical position. To improve such tire testing apparatus, the tire testing apparatus comprises upper bearing elements (8) which are movable relative to the lower bearing elements (7) and which together with the lower bearing elements (7) form a holder for the tire (17).

A tire testing device includes a carriage configured to rotatably hold a test wheel provided with a test tire and being capable of travelling on a base along a road surface in a state where the test wheel is made to contact the road surface, and a driving system configured to drive the test wheel and the carriage. The driving system includes a carriage driving part configured to drive the carriage with respect to the road surface in a predetermined speed, a test wheel driving part configured to drive the test wheel in a rotating speed corresponding to the predetermined speed, a driving part configured to generate power to be used to drive the carriage and the test wheel, and a power distributing part configured to distribute power generated by the driving part to the carriage driving part and the test wheel driving part.

Systems for detecting and monitoring tire pressure and temperature during a tire repair or replacement procedure are provided. The systems are configured to communicate a warning signal to a plurality of individuals (e.g., tire maintenance personnel) upon the tire pressure or temperature exceeding a defined threshold (e.g., upon the tire pressure or temperature entering a dangerous range). The system generally includes three categories of components, namely, components associated with a truck (or large work machine) and the tire being analyzed; a tire handler component; and a device that is worn (or held) by tire maintenance personnel, with such components being configured to wirelessly communicate with each other.
