Patent ID: 11897288

Abstract:
In a pneumatic tire, a block includes recess/protrusions on a road contact surface. Additionally, a recess/protrusion height of the recess/protrusions is from 0.1 mm to 1.0 mm. A width of the recess/protrusions is from 0.1 mm to 0.8 mm. A recess/protrusion region is where an arrangement interval between adjacent recess/protrusions is not greater than 1.2 mm. A smooth region other than the recess/protrusion region has an arithmetic mean roughness of the road contact surface of the block not greater than 50 μm. A lateral length of the road contact surface of the block in a tire lateral direction is defined. In this case, the block includes the recess/protrusion region and the smooth region in an optional cross-section in a lateral range of not less than 40% of a lateral length of the road contact surface of the block.
