Description:DUAL SHADING HIGH CONTRAST SIDEWALL PATTERN FOR TYRE

FIELD OF INVENTION
The present invention relates to the field of automobiles. Specifically, the present invention relates to sidewall of tyre. More specifically, the present invention relates to sidewall recitation for tyres through dual shading.
BACKGROUND OF THE INVENTION
From the existence of tyres, the sidewall has been the most important component of a tyre. To enhance the look and marketability of their products, tyre manufacturers have long used numerals, letters, characters or other designations on the sidewalls of their tyres. Since tyres have a significant influence on a car's personality, many automakers demand that their tyre suppliers brand their Original Equipment (OE) tyres with their own logos or codes on the sidewalls. Additionally, a tire's sidewall(s) are decorated with numerous patterns, letters, and other markings.
Moreover, sidewall(s) of a tire is/are provided with a lot of marks such as patterns, letters and the like. These marks are made by means of a tire mold, on surfaces of which groove structures are provided, and corresponding stripe structures are formed on the surfaces of the tire by vulcanization. A vulcanization mold for the tire is generally made of metal, the surfaces of the tire mold are often machined to be relative smooth, i.e. with higher smoothness. However, the outer surface of the tire obtained by this way, which is of black, is smooth, and such a smooth outer surface will reflect light rays, resulting in a deteriorated appearance of the surface of the tire.
One of the newest trends in tyre sidewall recitation is high contrast sidewall branding. The most popular technique for enhancing the brand on sidewalls with high contrast is laser texturing. Dual shading of branding is another technique that can be used for improvement in addition to laser texturing. This is possible with the aid of laser machining or 3D printing technology.

There are few of the reports available in the state of art about the existence of the tyre sidewall pattern.
USD543932S1 discloses a tire sidewall, the invention includes sidewall(s) of a tire is/are provided with a lot of marks such as patterns, letters and the like. These marks are made by means of a tire mold, on surfaces of which groove structures are provided, and corresponding stripe structures are formed on the surfaces of the tire by vulcanization. A vulcanization mold for the tire is generally made of metal, the surfaces of the tire mold are often machined to be relative smooth, i.e. with higher smoothness. However, the outer surface of the tire obtained by this way, which is of black, is smooth, and such a smooth outer surface will reflect light rays, resulting in a deteriorated appearance of the surface of the tire.
