Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing circumferential partial wear in an extremely small space while making a sacrificial wear not to worn off soon. SOLUTION: In at least one rib 3a of ribs 3, there is formed a partial sacrificial wear groove 4. The partial sacrificial wear groove 4 is made shallower than a circumferential main groove 1a to mark off the rib 3a. In a brand new wear-free state, at least a portion is configured to contact with the ground under the stipulation condition that the tire is mounted to the stipulated rim filled with stipulated inner pressure and a stipulated load is added.
