Abstract
This invention provides an automobile tire with communicating holes bored from the tire's tread to the sides of the tire. These holes permit snow or water which has come under the tire to be discharged to the outside through these communicating holes, thereby contributing to prevention of the tire's slip. For more effective discharge of snow or water, a well sliding surface material is applied on the inner surfaces of the communicating holes.
