PROBLEM TO BE SOLVED: To provide a pneumatic tire for certainly letting a driver recognize abrasion limit without sacrificing uneven wear-resistance property and wetting property. SOLUTION: A plurality of bottom up parts 4 having height equal to a wear indicator are formed on groove bottoms of a main groove 2 and an inclination groove 3 in a ground contact area R of a tread surface 1 with a gap in a circumferential direction of the tire. A ratio of the maximum value and the minimum value of arrangement pitch against the tire circumferential direction of the bottom up part 4 is made to be 1.0-1.2. COPYRIGHT: (C)2005,JPO&NCIPI |
