Patent number: 11312181Abstract: In a pneumatic tire, a lug groove is configured so that a portion thereof defining a leading side of a block in a rotation direction is inclined toward a trailing side in the rotation direction as that portion extends outward in a lateral direction from an equator line side. Among small blocks defined in the block by narrow grooves, a small block adjacent to the lug groove defining the leading side of the block in a rotation direction, and to a circumferential main groove defining the equator line side is a leading-side block, and a small block with a portion positioned on a backmost side of the block in the rotation direction is a trailing-side block. Among the small blocks, the trailing-side block has a greater surface area than that of the leading-side block, and intermediate blocks each have a greater surface area than the trailing-side block.Type: GrantFiled: August 30, 2017Date of Patent: April 26, 2022Inventor: Tomohiro Asano
