Abstract: An outer surface TS of a tire 2 includes a tread surface T and a pair of side surfaces S. A plurality of arcs representing a contour of the tread surface T include a pair of crown arcs. A ratio of a radius CR1 of a first crown arc to a radius CR2 of a second crown arc is not less than 1.10 and not greater than 1.70. A total groove volume of a first circumferential groove 48 located in a zone from an equator to a first tread reference end TE1 is larger than a total groove volume of a second circumferential groove 50 located in a zone from the equator to a second tread reference end TE2.

Abstract: A tread for a heavy truck tire is provided that has a bottom surface (14), a shoulder rib (16), and a sacrificial rib (20) located outboard from the shoulder rib (16) in a width direction. A decoupling void (30) is located between the shoulder rib (16) and the sacrificial rib (20). First decoupling void sipes (32), second decoupling void sipes (100) and third decoupling void sipes (104) are in the shoulder rib (16), and one second decoupling void sipe (100) is between one first decoupling void sipe (32) and one third decoupling void sipe (104). The first and third decoupling void sipes (32, 104) are closer to the bottom surface (14) than is the decoupling void (30) in the thickness direction. The second decoupling void sipe (100) is not closer to the bottom surface (14) than is the decoupling void (30) to the bottom surface (14) in the thickness direction.

Abstract: To provide a pneumatic tire that provides improved driving performance on unpaved roads and cut resistance. High blocks and low blocks with different raised heights are provided as side blocks provided in a side region. One of the high blocks and one of the low blocks adjacent to each other in a tire circumferential direction are defined as a block pair. The high block and the low block included in the block pair are partially in contact with each other. Thus, a side groove between these blocks is a closed groove. In each block pair, a pair of contour lines (a first linear portion, a second linear portion, and a third linear portion) define edges on both sides, in the tire circumferential direction, of a top surface of each of the high block and the low block.

Abstract: In a tire, a first side block comprises a first recess which opens so as to be directed toward a first circumferential direction, and a second recess which opens so as to be directed toward a second circumferential direction which is opposite the first circumferential direction in a tire circumferential direction. The first side block comprises a first region, a second region, and a first step which is between the first region and the second region and which is formed by a difference in heights by which the first region and the second region protrude.

Abstract: A pneumatic includes a pair of sidewall portions. At least one of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on a radially inner side. Both protruding portions are formed so as to be convex outward in a tire axial direction. The second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from an outer surface of the first protruding portion. A distance in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length in the tire radial direction of the second protruding portion.

Abstract: In a pneumatic tire, a tread portion is provided with center blocks and shoulder blocks, and sidewall portions are each provided with side blocks. Surfaces of the blocks are provided with groove elements each including a narrow groove and/or a sipe. The first groove elements provided in the side blocks, the second groove elements provided in the shoulder blocks, and the third groove elements provided in the center blocks form a set of lateral groove group extending continuously from the side block on a first side to the side block on a second side in the tire lateral direction along the blocks across a main groove or an auxiliary groove.
