<p>A pneumatic tire whose stone drilling resistance is improved while sufficient snow traction ability is achieved. Projections (30) that are lower in height than a block section (15) and separated from the block section (15) are intermittently arranged in a groove (20). The projections (30) are each constructed from a projection body (31) with a top section (32) and inclined sections (35) each having a slope (36) that is formed at an angle ? in the range of 3° - 60° measured between the slope and a groove bottom (24). The inclined sections (35) are formed at two positions along at least the groove (20), in the directions opposite to each other. A stone that the groove (20) bites moves along the slope (36) to the top section (32) and is discharged from the groove (20). Further, since the projections (30) are separated from the block section (15) and intermittently arranged, the volume of the groove (20) is at a sufficient level. As a result, the pneumatic tire is improved in stone drilling resistance while achieving sufficient snow traction ability.</p> |
