Abstract
A pneumatic tire comprises at least one block partitioned by a block partitioning groove, the at least one block comprises a first block groove extending from an edge toward a first side in a tire circumferential direction of the at least one block so as to be directed toward a second side in the tire circumferential direction, and a second block groove extending from an edge toward the second side in the tire circumferential direction of the at least one block so as to be directed toward the first side in the tire circumferential direction, and the first block groove and the second block groove appear to overlap as viewed in a tire width direction.
Claims10
A pneumatic tire comprising at least one block partitioned by a block partitioning groove;
- wherein the at least one block comprises a first block groove extending from an edge at a corner of the at least one block toward a first side in a tire circumferential direction of the at least one block so as to be directed toward a second side in the tire circumferential direction, and a second block groove extending from an edge at another corner of the at least one block toward the second side in the tire circumferential direction of the at least one block so as to be directed toward the first side in the tire circumferential direction;
- and
- wherein the first block groove and the second block groove overlap as viewed in a tire width direction, and
- wherein each of the first block groove and the second block groove has an edge which extends at an angle of less than 30° with respect to the tire circumferential direction.
A pneumatic tire comprising at least one block partitioned by a block partitioning groove;
- wherein the at least one block comprises a first block groove extending from an edge toward a first side in a tire circumferential direction of the at least one block so as to be directed toward a second side in the tire circumferential direction, and a second block groove extending from an edge toward the second side in the tire circumferential direction of the at least one block so as to be directed toward the first side in the tire circumferential direction;
- and
- wherein the first block groove and the second block groove overlap as viewed in a tire width direction,
- wherein the at least one block comprises a block central portion which is arranged between the first and second block grooves, a first block base portion which is contiguous with the block central portion, and a first block protruding portion which protrudes from the first block base portion in such fashion as to, together with the block central portion, straddle the first block groove;
- and
- wherein width of the first block protruding portion decreases as one proceeds toward a tip thereof.
A pneumatic tire comprising at least one block partitioned by a block partitioning groove;
- wherein the at least one block comprises a first block groove extending from an edge toward a first side in a tire circumferential direction of the at least one block so as to be directed toward a second side in the tire circumferential direction, and a second block groove extending from an edge toward the second side in the tire circumferential direction of the at least one block so as to be directed toward the first side in the tire circumferential direction;
- and
- wherein the first block groove and the second block groove overlap as viewed in a tire width direction,
- wherein the at least one block comprises a block central portion which is arranged between the first and second block grooves;
- a first block base portion which is contiguous with the block central portion;
- a first block protruding portion which protrudes from the first block base portion in such fashion as to, together with the block central portion, straddle the first block groove;
- a second block base portion which is contiguous with the block central portion;
- and a second block protruding portion which protrudes from the second block base portion in such fashion as to, together with the block central portion, straddle the second block groove;
- and
- wherein an angle at a corner which is in the block central portion but which is adjacent to neither the first nor the second block base portion is greater than an angle at a corner which is in the first block base portion but which is adjacent to neither the block central portion nor the first block protruding portion.
