The invention provides a tire with a color safety mark and relates to a process for applying color rubber to tires, which is characterized by using white carbon black (the grain diameter thereof ranges from 11 to 19) or adding a coupling agent Si-69 to enable colored rubber materials to have the same wear resistance and workability as those of a tire surface; improving the tire surface and the mouthpiece of an extruder mouthpiece plate; improving the colored rubber materials of the extruder mouthpiece plate; and improving an upper roller, a side roller and a preset steel plate of a three-roller calendar. The technical process is as follows: The colored rubber materials with an improved formula are respectively extruded into four colored rubber strips through the extruder mouthpiece plate and extruded into tire surface rubber sheets separating two inverted triangular grooves through the two inverted triangular block mouthpieces of the tire surface extruder mouthpiece plate; the four colored rubber strips are respectively embedded and compounded to the tire surface rubber sheets, i.e. the tire surface rubber sheets of the tire with the color safety mark, through the preset steel plate and the side roller of the calendar during accurate rolling moment by two correspondingly raised triangular rings of the upper roller of the three-roller calendar.
