To improve braking performance on dry road surfaces, wet road surfaces, and snowy road surfaces. A pneumatic tire has, in a tread surface (2a) of a tread part (2): central lands (4Aa, 4Ba) formed by individual lands (4A, 4B) being divided in the tire circumference direction by three circumference-direction grooves (3A, 3B, 3C) extending along the tire circumference direction and main lug grooves (5AA, 5BA); long small lands (4Ab, 4Bb) provided to be long in the tire circumference direction and formed by the central lands (4Aa, 4Ba) being divided by each of the circumference-direction grooves (3A, 3C) on the outer side in the tire width direction, the main lug grooves (5AA, 5BA), and circumference-direction thin grooves (6A, 6B); and two short-length small lands (4Ac1, 4Ac2, 4Bc1, 4Bc2) provided to be short in the tire circumference direction and formed by the central lands (4Aa, 4Ba) being divided by the circumference-direction groove (3B) in the center in the tire width direction, the main lug grooves (5AA, 5BA), sub lug grooves (5AB, 5BB), and the circumference-direction thin grooves (6A, 6B). |
