As shown in FIGS. 1 and 3, the left abnormal tire pressure indicator portion 3a has a tire pressure shortage warning portion 31 and a dangerous tire pressure warning portion 32, and the right abnormal tire pressure indicator portion 3b has a tire pressure shortage warning portion. 33 and a dangerous tire pressure warning portion 34, whereby the abnormal tire pressure can be easily determined by having the left and right side abnormal tire pressure indicating portions, and the abnormal tire pressure can be determined in detail as insufficient tire pressure or dangerous tire Pressure.

Preferably, the normal tire pressure indicating portion 2 and the abnormal tire pressure indicating portion 3 may be color indicating portions of different colors. Thereby, the user can intuitively judge the extent to which the tire pressure indicator portion is worn after running. Of course, the normal tire pressure indicating portion 2 and the abnormal tire pressure indicating portion 3 are not limited thereto. In other embodiments, the normal tire pressure indicating portion 2 and the abnormal tire pressure indicating portion 3 are color indicating portions of the same color. The normal tire pressure indicating portion 2 and the abnormal tire pressure indicating portion 3 can be distinguished by having a character mark. In the case where the abnormal tire pressure indicating portion 3 further divides the tire pressure shortage warning portion and the dangerous tire pressure warning portion, the normal tire pressure indicating portion 2, the tire pressure shortage warning portion 31, and the dangerous tire pressure warning portion 32 may be The color is marked for the color of the different colors.

As shown in FIGS. 4 to 6, the safety tire pressure indicating member 1 is disposed after the tread portion T1, and the tire T is driven under normal tire pressure and different degrees of abnormal tire pressure. The tire pressure is worn to varying degrees due to changes in the range in which the tread portion T1 is in contact with the ground.

At the time of the normal tire pressure, the safety tire pressure indicating member 1 only wears the portion of the normal tire pressure indicating portion 2 that is in contact with the ground after running, and a portion of the normal tire pressure indicating portion 2 is left on the tread portion T1. It is judged that the tire pressure of the tire T is a normal tire pressure (Fig. 4). When the tire T does not reach the normal tire pressure but does not immediately harm the vehicle, the entire normal tire pressure indicator portion 2 and the portion of the tire pressure shortage warning portion 31, 33 that is in contact with the ground are worn after traveling. A part of the tire pressure-deficient warning portions 31 and 33 are left on the tread portion T1, whereby the tire pressure of the tire T is determined to be insufficient in tire pressure (Fig. 5). When the tire T does not reach the normal tire pressure and there is an immediate danger to the vehicle running, the normal tire pressure indicator portion 2, all of the tire pressure shortage warning portions 31, 33 and the dangerous tire pressure are all worn after running. The portion of the warning portion 32, 34 that is in contact with the ground, and the portion of the dangerous tire pressure warning portion 32, 34 are left on the tread portion T1, thereby determining that the tire pressure of the tire T is a dangerous tire pressure.
