Abstract: An automobile tire having an anti-skidding function and useful throughout all seasons is provided which permits the automobile to run while maintaining the anti-skidding function even if it encounters a snowless road during a travel on a snow-covered road, which does not require frequent operations of extending and retracting the spike pins and which poses no problem of pollution. Air chambers 3 are formed in the tread 2 of the tire. Branch tubes 4A of an air supply and evacuation tube 4 are connected with the air chambers 3. The tread surface has bosses 2B extending outwardly therefrom at locations corresponding to those portions 2A of the peripheral walls of the air chambers facing the tread surface, the bosses allowing portions of the tread to be bulged from and depressed into the tread surface depending on the air pressure in the air chambers. On-off valve means 6 may be provided in connecting portions between the air chambers 3 and the air supply and evacuation tube 4.
