Abstract

PURPOSE:To provide a pneumatic tire having a decorative means enabling decoration with various colors with a simple structure even to a high performance tire. CONSTITUTION:A tire T is provided with an annular tread 1, a pair of side walls 2 extended radially from both ends of the tread 1, a bead part 3 provided at the radial inner end of each side wall 2, and an annular bead core 4 embedded in the bead part 3. An annular recessed groove 5 to be the concentric circle with the tire T is provided at the appropriate place of the side wall 2. The bottom face of the recessed groove 5 is formed into a plane, desirably formed in such a way as to become the plane at the time of charging air, and both side walls are protruded onto the outside of the tire from the outer surface of the side wall 2 so as to form a pair of annular protectors 6, 6. A sticker 7 hard to peel off and high in heat resistance and rain resistance is stuck into the annular recessed groove 5 for decoration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire having an improved design by decorating a sidewall.

[0002]

2. Description of the Related Art Conventionally, in order to improve the fashionability of automobiles, particularly passenger cars, white rubber such as PCR has been used as a decoration for tire sidewalls, and a white line or letters or symbols formed in an annular shape concentric with the tire. Generally, a white letter in which the above is formed is known.

[0003]

However, in the above-mentioned conventional white line, white letter, etc., which is the decoration of the side wall, discoloration due to structural contamination in which carbon or the like penetrates from the surrounding black rubber is apt to occur, The rubber around the white rubber must be non-staining, and it is necessary to dispose a rubber of a different material from the usual one, which complicates the composition of the rubber and increases the durability of the white rubber itself. Since it is low, there is a problem that it is difficult to adopt it in a high-performance tire that runs at high speed. In addition, since the white rubber is easily soiled, the adjacent tires are rubbed against each other during transportation or the like, so that the white rubber is likely to be blackly soiled, and there is a problem that a protective tape needs to be attached onto the white rubber during shipping. . Furthermore, because it uses white rubber,
There was a problem that it was not possible to obtain a highly fashionable decoration using other colors, which was limited to only white.

The object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a pneumatic tire equipped with a decoration means that can be decorated with various colors with a simple structure and can be applied to a high performance tire.

[0005]

In order to achieve the above object, a pneumatic tire of the present invention comprises an annular tread, a pair of sidewalls extending radially from both ends of the tread, and radially inner ends of the sidewalls. In a pneumatic tire having a bead portion formed in, a ring-shaped concave groove concentric with the tire is provided at an appropriate place on the sidewall, a bottom surface of the concave groove is formed into a flat surface, and heat resistance and a bottom surface of the concave groove are formed. It is a sticker that is highly resistant to rain and is hard to peel off. It can be decorated with various colors with a simple structure and can be applied to high-performance tires.

[0006]

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, a tire T includes an annular tread 1, a pair of sidewalls 2 extending from both ends of the tread 1 in a radial direction, a bead portion 3 at a radially inner end of each sidewall 2, and a bead portion 3. The embedded annular bead core 4 is provided.

As shown in FIG. 2, an annular groove 5 which is concentric with the tire T is provided at an appropriate position on the sidewall 2, and a bottom surface 51 of the groove 5 is formed into a flat surface as shown in FIG. Then, it is preferably formed so as to be flat when air is filled, and the side walls 52, 52 are projected to the outside of the tire beyond the outer surface of the side wall 2 to form a pair of annular protectors 6, 6. In the annular groove 5, the heat resistance and the rain resistance are high,
A sticker 7 that is hard to peel off is used as a decoration (Fig. 1
And FIG. 3).

According to the above construction, since only the groove 5 is provided in the side wall 2, the manufacturing is easy, no new equipment is required, and the sticker 7 can be attached at any time (for example, when the tire is mounted). ) Can be selected,
No need for protective tape when shipping. Also, the sticker 7
If it is damaged or contaminated, it can be easily replaced and durability does not matter, so it can be used for high performance tires, and the color and design of the sticker 7 can be arbitrarily selected. Therefore, it makes it possible to color the tire and coordinate with the wheel design to improve the fashionability of the car. Further, by providing the annular protector 6, the sticker 7 is not damaged even when the sidewall 2 comes into contact with a curb or the like on the road.

[0009]

Since the present invention is constructed as described above, it has the following effects. It is easy to manufacture because it only has a groove on the side wall, no new equipment is required, and the sticker can be attached at any time, so the protective tape is not required at the time of shipping.
In addition, the sticker can be easily replaced if it is damaged or contaminated, and durability does not matter, so it can be used for high-performance tires, and the color and design of the sticker can be changed according to the user's preference. The color of the tire can be changed at the same time, and at the same time it can be coordinated with the wheel design to improve the fashionability of the automobile.
