Description

Tire {A tire} The present invention relates to a tire. Vehicles operated by users consist of many parts, among which tires have a significant impact on the vehicle's operation and can be considered one of the key components for ensuring user safety. In particular, due to industrial development, the volume of vehicle travel is on an increasing trend driven by increased logistics, increased personal workloads, and the expansion of family life. Meanwhile, tires maintain driving safety through friction with the road surface; however, if driving is not controlled according to the driver's intentions due to road conditions—that is, if the tires are not controlled as desired on the road surface—the stability of the vehicle and the driver may be compromised. In addition, continuous driving of the vehicle can cause tire wear, and issues regarding tire durability and safety may arise.

Figure 6a is an enlarged view of J in Figure 5 with respect to a tire before wear. FIG. 6b is an enlarged view of J in FIG. 5 with respect to the tire after wear. Figure 7 is a drawing illustrating a variation of Figure 5. Figure 8 is an enlarged view of Figure 7. Figure 9 is a drawing illustrating a variation of Figure 8. FIG. 10 is a schematic plan view illustrating the tread portion of a tire according to one embodiment of the present invention. FIG. 11 is a drawing illustrating a variation of FIG. 10. The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various forms. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component. In the following examples, singular expressions include plural expressions unless the context clearly indicates otherwise. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the present invention is not necessarily limited to what is illustrated. In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system and can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they may also refer to different directions that are not orthogonal to each other. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description. FIG. 1 is a front view schematically illustrating a tire according to one embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1, and FIG. 3 is a block diagram illustrating a modified example of FIG. 1. Referring to FIGS. 1 to 3, the tire (100) of the present embodiment may include a tread portion (110), a groove (115), a sidewall (180), a sensor portion (150), and an output portion (20). The tire (100) may have a shape that extends in the circumferential direction (RT) around a central axis (AX). Additionally, a wheel (not shown) may be attached to the inner side of the tire (100) based on the radial direction (r) from the central axis (AX). The tread portion (110) may include an area facing the road surface when the tire (100) is mounted on a vehicle
