The present invention relates to an intelligent tire for informing wear state and replacement time, and particularly, when a plurality of road grounding sensors are inserted at a wear limit position inside a tread, and the tread is worn, and the road grounding sensor is grounded on a road surface. By sending the signal to the instrument panel of the vehicle to display, it relates to an intelligent tire that informs the wear state and replacement time so that anyone can easily know the wear state and replacement time of the tire.

Generally, a tire is made to exhibit the performance, such as riding comfort, noise, and maneuverability, to the maximum at the beginning.

As shown in FIG. 1, the tire includes an inner liner 10 constituting the inside of the tire, a carcass 20 stacked on an outer circumference of the inner liner 10, and the carcass 20. A belt 30 stacked on at least two layers on an outer circumference, a tread 40 stacked on an outer circumference of the belt 30 and substantially in contact with the ground, and both sidewalls 50 and 50 constituting both sides of the tire. ) And both beads 60 and 60 coupled to the wheel to maintain the air pressure. Such tire technology is well disclosed in Korean Patent Application Laid-Open No. 2005-51103 and Korean Patent Application No. 2005-35438. .

On the other hand, as the tire running time elapses, wear of the tread 40 proceeds and thus the initial performance of the tire decreases, and when the progress of wear is serious, tire rupture may occur. Therefore, the tire should be replaced at an appropriate time before a tire accident due to wear occurs. However, many drivers often drive the vehicle as it is, exceeding the wear limit of the tire. This is because drivers are not good at judging the wear limits of tires and are not aware of the risks of tires that are out of wear limits.

In the related art, as shown in FIG. 1, wear indicators 42 made of small rubber blocks are formed at predetermined intervals in the longitudinal groove 41 of the tread 40, and the wear according to the wear of the tread 40 is performed. When the indicator 42 is exposed to the ground, the driver recognizes that the tire has reached the wear limit and causes the driver to replace the tire, but the wear indicator 42 is made of the same material and color as the tread 40. Since it is displayed and its size is so small that it is not well recognized by the driver, there is a problem that the risk of wear is not well communicated to the driver.

In addition, the wear indicator 42 may be formed by inserting a rubber of a different color from the tread 40 into the inside of the longitudinal groove 41, even if the wear indicator 42 is different from the inside of the longitudinal groove 41. Since it is displayed, this also does not inform the driver of the degree of wear well, and as a result, a big accident may occur when driving a slippery road, for example, while missing tires.

The present invention has been made in consideration of the above-described conventional problems, and when a plurality of road grounding sensors are inserted at a wear limit position inside a tread, and the tread is worn, the road grounding sensor is grounded on a road surface, the signal of the vehicle. It is intended to make it easy for anyone to know the tire wear condition and replacement time by sending it to the dashboard.

In order to achieve the above object, the present invention includes a plurality of longitudinal grooves formed in the circumferential direction and a plurality of center tread blocks and both tread shoulders formed by the longitudinal grooves, A tire comprising a tread divided by a cap tread to be stacked: a road ground to which the ground signal is individually transmitted to the instrument panel of the vehicle and displayed when the tread is grounded to the road surface according to the wear of the tread. A plurality of sensors are inserted.

According to the present invention, it is preferable that the road surface ground sensor is inserted into the center of the tread and the both tread shoulders, respectively, one at a position between the under tread and the cap tread.

In addition, the road grounding sensor has a width of 15 ~ 20mm, it is preferably inserted into the tread so that the position of the upper surface corresponding to the height of 1.6mm from the bottom surface of the longitudinal groove.

In addition, a plurality of wear indicators having a height of 1.6 mm from the bottom surface of the longitudinal groove may be installed at predetermined intervals along the circumferential direction.
