Description

この発明は、いろいろな乗り物等に使用されている、タイヤに関するものである。
従来は、タイヤについては、スリップサイン（大型トラックは残溝３．２ｍｍ等）（乗用車は残溝１．６ｍｍ等）が出れば交換の目安となります。また、目で見てタイヤの溝がなくなれば、交換の目安としてきました。
しかしタイヤの色はほとんどが黒色▲１▼で、（特殊なものは、白色、緑色）摩耗がすすんでも、注視しないと、なかなかそのことに気がつきません。
そこで摩耗がすすみタイヤの残溝がほとんどなくなり、走行に支障をきたしたり、危険になってくると、タイヤの中から▲２▼白色、黄色、水色などなどの別の色のゴムやプラスチックなどなどの素材のものが出てきて、交換の目安・サインとなるものである。スリップサインの代用もできる。（元々が白色、緑色などの場合は、黒とか青とかなどの別の色を用いる。）
【図面の簡単な説明】
【図１】本発明のタイヤの断面図である。
【符号の説明】
▲１▼はタイヤの通常のゴムの層　　▲２▼は通常のゴムの層とは色の違う層
▲３▼はベルト部分（糸・ワイヤーなどの骨格層）The present invention relates to a tire used for various vehicles and the like.
Conventionally, if tires come out with a slip sign (such as 3.2 mm for grooves on large trucks) (1.6 mm for grooves for passenger cars), it will be a guide for replacement. Also, if the tire groove disappears visually, it has been used as a guide for replacement.
However, the color of the tire is mostly black (1), and (special ones are white and green). Even if the wear progresses, it is difficult to notice it unless you pay close attention.
Then, the tires are worn out, and the remaining grooves on the tires are almost gone, hindering driving or becoming dangerous. If the tire becomes dangerous, you can choose from different colors such as rubber, plastic, etc. It comes out of the material of the material, and it is an indication and a sign of the exchange. You can use a slip sign instead. (If the color is originally white or green, another color such as black or blue is used.)
[Brief description of the drawings]
FIG. 1 is a sectional view of a tire according to the present invention.
[Explanation of symbols]
(1) is a normal rubber layer of the tire. (2) is a layer different in color from the normal rubber layer. (3) is a belt portion (skeleton layer of thread, wire, etc.).

Claims

Used for bicycles, motorcycles, passenger cars, dump trucks, trucks, etc. When the tires are worn and the life of the tires is approaching, it will be different from the conventional black from among the tires (white, yellow, etc.) Items such as rubber and plastic come out and make it easier to recognize wear, life, danger, etc. due to the difference in color.
A tire incorporating the above contents.
