Automotive tire

A pneumatic tire of the present disclosure includes: a pair of main grooves, lateral grooves and longitudinal grooves, wherein a center land, repeats, in the tire circumferential direction, four center blocks, each of the four center blocks includes a recessed portion that is open to the main groove, the lateral groove or the longitudinal groove and has one end closed, when the recessed portions provided in the four center blocks are defined as first to fourth recessed portions, the first recessed portion and the second recessed portion extend in a direction inclined to one direction with respect to the tire equator line, and the third recessed portion and the fourth recessed portion extend in a direction inclined to another direction with respect to the tire equator line, and a groove width of each of the first to fourth recessed portions is 5.0 mm or more.

Pneumatic tire

A plurality of side blocks each has a high protruding portion, an amount by which the high protruding portion protrudes relative to a reference surface which is an exterior surface in a region peripheral to an insignia being not less than a maximum amount by which the insignia protrudes relative to the reference surface. The plurality of side blocks include a first side block which as viewed in the tire radial direction appears to overlap the insignia, and a second side block which as viewed in the tire radial direction appears not to overlap the insignia. An inner end in the tire radial direction of the high protruding portion of the first side block is separated in the tire radial direction from the insignia, and a portion of the high protruding portion of the second side block appears to overlap the insignia as viewed in the tire circumferential direction.

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.
