A tread rubber composition for tires, including a sublimation dye that is activated by heat generated by frictional contact with a road surface to generate smoke having various colors at a wavelength of about 39-76×10−6 cm (390 nm to 760 nm) in a frequency range of about 39.5˜77×1013 vps (39.5×1013 Hz to 77×1013 Hz. In addition, a tire including the tread rubber composition and a method of manufacturing the tread rubber composition are also provided. According to the current invention, the tread rubber composition included in the tire can generate smoke having a single color or mixed colors selected from among various colors, therefore obtaining smoke that gives optimal enjoyment and satisfies requirements of drivers at motor sports events, such as drifting.
Tire for a motor sport vehicle, said tire comprising a rubber tread incorporating therein a heat activated sublimating dye, said tire, upon frictional engagement with a substrate, producing a smoke having a desirable color within the visible spectrum of electromagnetic radiation of wavelengths.
Vehicle tire, said tire comprising a rubber tread incorporating therein a heat activated sublimating dye, said tire, upon frictional engagement with a substrate, producing a smoke having a desirable color within the visible spectrum of electromagnetic radiation of wavelengths.
A tire comprising a tread rubber composition, said tread rubber composition comprising a mixture of rubber and a sublimation dye, said sublimation dye being activated by heat generated by frictional contact with a road surface to generate smoke having various colors at a wavelength of about 39˜76×10−6 cm in a frequency range of about 39.5˜77×1013 vps.
A method of manufacturing a tread rubber composition comprising mixing a material for a tread rubber composition comprising rubber and a sublimation dye, said sublimation dye being activated by heat generated by frictional contact with a road surface to generate smoke having colors at a wavelength of between about 39˜76×10−6 cm in a frequency range of between about 39.5˜77×1013 vps wherein the sublimation dye is used in an amount from about 5 to about 10 wt % based on the total weight of the tread rubber composition.
