Abstract: Proposed is a tire with self-generation and sound absorption and, more particularly, is a tire with self-generation and sound absorption that operates an electronic module through self-power generation and has improved sound absorption performance. The tire with self-generation and sound absorption includes: a wall structure formed on a surface of an inner liner of the tire; a sound absorber spaced apart upward from the inner liner with both ends coupled to the wall structure and blocking sound generated by surfaces of treads and a road surface; and an electronic unit disposed on the surface of the inner liner and positioned between the inner liner and the sound absorber.

Abstract: The present disclosure relates to a tire having characters such as a brand name, a model name, etc. engraved on a sidewall thereof. The tire of the present disclosure includes a plurality of knurling units that includes: a first knurling part that is convex; a second knurling part that continues from a side of the first knurling part and is convex; a third knurling part that continues from a side of the second knurling part and is convex; and a fourth knurling part that is convex and is continuously connected from a side of the third knurling part to another side of the first knurling part.

Abstract: Provided is a technology of estimating a bending stiffness variation of a tire and estimating a tread wear amount of a tire using the same. A tire wear measuring apparatus wear includes a signal receiver configured to measure acceleration inside the tire with respect to an axial direction, which is a radial direction of the tire, for each point inside the tire, a signal analyzer configured to receive signal information from the signal receiver and estimate a tread wear rate of the tire by calculating a bending stiffness variation rate of the tire using axial acceleration inside the tire, a transmitter configured to receive and transmit analysis information, which is information on the tread wear rate of the tire, from the signal analyzer, and a control module configured to receive the analysis information from the transmitter and generate a control signal for a vehicle to which the tire is installed.

Abstract: The present disclosure relates to an adhesive composition and a method of manufacturing a nonpneumatic tire using the same, and more specifically, to an adhesive composition comprising a linear structured prepolymer for polyurethane having a cyclic carbonate group at both ends thereof and a polyfunctional amine, and a method of manufacturing a nonpneumatic tire using the same.

Abstract: Provided is a technique of quantifying a change in irregularity appearing in an acceleration signal of a tire and measuring a tread wear amount of the tire using the quantified change.

Abstract: Provided is a technique for measuring a wear rate of a tire tread using tendency of a peak value of acceleration of the tire. According to an embodiment of the present disclosure, a tire wear measuring apparatus includes: a signal receiver configured to measure acceleration inside the tire installed to a the vehicle for each point inside the tire; a signal analyzer configured to receive signal information from the signal receiver and estimate a tread wear rate of the tire using a peak value of acceleration in longitudinal direction perpendicular to an axial direction of the tire from among acceleration signals inside the tire; a transmitter configured to receive analysis information, which is information on the tread wear rate of the tire, from the signal analyzer and transmit the analysis information; and a control module configured to receive the analysis information from the transmitter and generate a control signal for the vehicle to which the tire is installed.

Abstract: There is provided a pneumatic tire with a reinforcing part which is mounted on a tire wheel, the pneumatic tire including: a tread having a groove that is formed in a circumferential direction of the tire wheel as being recessed toward a central axis of the tire wheel, a kerf that is formed to intersect the groove as being recessed toward the central axis of the tire wheel, and one or more blocks that are formed between the groove and the kerf and come into contact with a road surface; a shoulder formed at a side of the tread; and a reinforcing part inserted into the groove formed between the one or more blocks. The reinforcing part reduces noise produced due to contact with the road surface by being bent one or more times.
