Abstract

To provide a pneumatic tire which is excellent in brake performance while maintaining low rolling resistance.SOLUTION: A pneumatic tire 1 is a tire having a designated main rotation direction. A tread 10 of the pneumatic tire 1 has center blocks 30 and 40, shoulder blocks 50 and 60, and mediate blocks 70 and 80. The pneumatic tire 1 has a ratio (L2 / L1) of a ground length (L2) in a tire circumferential direction at a point located 10 mm inside from a ground end E to a ground length (L1) in a tire circumferential direction of a width direction center region R1 of the tread 10 of 0.75-0.90, in a state of an inner pressure of 200-260 kPa, and a load of 70% of maximum load capacity.SELECTED DRAWING: Figure 3
