A pneumatic tire is provided, the pneumatic tire including a tread portion, sidewall portions, and bead portions, and the pneumatic tire includes, in the tread portion, a center main groove extending in a tire circumferential direction and a shoulder main groove extending in the tire circumferential direction on the outside of the center main groove; a land portion between the main grooves; lug grooves extending inward in a tire lateral direction from the shoulder main groove and terminating without communicating with the center main groove; a bent portion bending toward one side in the tire circumferential direction, at a terminating end of each of the lug grooves; and a raised bottom portion included in the bent portion, creating a level difference with respect to a lug groove, and being shallower than the lug groove.

Provided is a tire. At least one of sidewall portions includes a plurality of side blocks rising from a surface of the at least one of sidewall portions and a plurality of side grooves defined by the side blocks adjacent to each other in a tire circumferential direction, one end of the plurality of side grooves opening to an inner side in a tire radial direction. A land ratio of an area of a region of the side blocks to an area of a region defined by a first imaginary line along a ridge, which is a mold split position, and a second imaginary line along an individual leading edge portion on the inner side of a plurality of the side blocks in the tire radial direction is in a range 40%≤R1≤80%.

A tread portion is provided with a first block and a second block, which protrudes outward in a tire width direction more than the first block, alternately in a tire circumferential direction in a shoulder region. A first projection is provided in an outer side of the first block, and a second projection is provided in an outer side of the second block. An outside end of the second projection is connected to a side surface of the second block and is arranged closer to an outer side in the tire diametrical direction than an outside end of the first projection. An angle θ1 formed by a side surface of the first projection and a surface of the side wall portion is equal to or smaller than an angle θ2 formed by a side surface of the second projection and the surface of the side wall portion.

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.

A pneumatic tire has a pair of sidewall portions. An outer surface in a tire axial direction of at least one of the sidewall portions includes a base surface, at least one first protruding portion protruding more outward in the tire axial direction than the base surface, and a recessed portion extending on the base surface around the first protruding portion such that the first protruding portion is spaced apart from the base surface. The first protruding portion includes a first surface having a first protruding amount with respect to the base surface, and a second surface having a second protruding amount different from the first protruding amount with respect to the base surface, and the first surface and the second surface are connected so as to form a step.

A tire 2 has a nominal aspect ratio of 65% or less. The tire 2 includes a tread 4, a pair of sidewalls 6, a pair of chafers 8, a pair of beads 10, and a band 40. The band 40 includes a full band 44 having ends 44e opposed to each other across an equator plane, and a pair of edge bands 46 located outward of the ends 44e of the full band 44 in a radial direction. An outer surface of each chafer 8 has a fitting recess 62 into which a flange F of a rim R fits.
