In 80s, the developed countries Japan, Germany and the United States have re production and put into the side of the tire with white font or ring tire, American Goodyear company even designed a fully transparent tire, it can be lit at night. In 90s, the French Michelin Co and a chemical group, substituted carbon dioxide, and achieved good results. Since the intrinsic color of silica is white, you can add any different staining agent, and you can choose any color from it. In recent years, with the emergence of new rubber anti-aging agent and white and light rubber reinforcing agent, the development of decorative tire is further promoted. Nevertheless, colored tyres are always used only as decorative tyres, and their cost, performance, and many other aspects are still not comparable to those of black tyres that have been used for decades.
In twentieth Century, three and 40s, many foreign car holders in order to show their wealth and social status, have been painted on the outside wall of the tire white paint, to distinguish others, reflect individuality. But the biggest disadvantage of this cosmetic method is that the paint will peel off gradually after the use of the tire for a period of time, and the tread on the tire side is very unsightly. This method has gradually been left out of the cold. By 2501s, the white rubber tire using white rubber and recovery, but the tire strength and resistance to rip poor performance, aging resistance performance is poor, the cost is more expensive, the use of time is slightly long, the rubber will gradually become yellow and brown, lost the original decorative effect.
In fact, as early as nineteenth Century, the car rubber tires due to different additives, the color is not fixed. By 1915, due to the process of using carbon and hydrocarbons to condense at high temperature, the rubber appeared as pure black as ink, and its wear resistance reached an unprecedented level. Since then, rubber tires have entered a long period of black domination.
