<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire in which a brake performance on ice, a brake performance on snow, and a drainage performance are improved with a good balance.SOLUTION: Circumferential-direction narrow grooves 18 are disposed with a tire width-direction density between 0.06 piece/mm and 0.2 piece/mm. Since a width-direction narrow grooves 22 has at least one bent part, small block rows have feather shaped small blocks B1 arranged continuously in the tire circumferential direction. A bent angleαon the feather front-end side, and a bent angleβon the feather rear-end side of the block B1 are 40° or more and 160° or less, respectively. The bent angleαis greater than the bent angleβ.</p> |
