Vehicle tyre comprises surface raised areas and depressions, and a height or depth equivalent to the wavelength of visible light

摘要

Vehicle tyres comprise surface raised areas (1) and depressions (2), the height and depth of which correspond to the wavelength of visible light. The raised or depression areas have a period which is less than the wavelength of visible light. The depressions are V-shaped and are in the form of grooves. The grooves are straight and can cross over one another. Vehicle tyres comprise surface raised areas (1) and depressions (2), the height and depth of which correspond to the wavelength of visible light. The raised or depression areas have a period which is less than the wavelength of visible light. The depressions are V-shaped and are in the form of grooves. The grooves are straight and can cross over one another. The raised areas and depressions can consist of nodules. The ratio of raised or depressed area to period is about one, and the raised or depressed areas have a roof shaped pattern. The raised and depressed areas are not visible to the naked eye.
