<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. The width-direction narrow grooves 22 includes: a first part 221 and a second part 222 extending to the tire circumferential direction from both end portions in the tire width-direction of each of small block rows; and a third part 223 connected to both of the first part 221 and a second part 222. An angle between the first part 221 and a second part 222 is between 40° and 160°. The third part 223 has one or more areas which are protruded from extended areas of the first part 221 and second part 222 at least in any direction of the tire circumferential directions.</p> |
