Problems solved by technology

According to this, the rigidity of the buttress portion (the outer end region in the tire radial direction of the sidewall portion) can be made uniform in the tire circumferential direction, but the traction performance cannot be sufficiently improved (for example, the surface of the sidewall block or the The ability of edge components to generate traction when they come into contact with soil, sand, or rocks)

Embodiment Construction

[0019] Below, refer to Figure 1 to Figure 8 , an embodiment of a pneumatic tire will be described. In addition, in each drawing, the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match.

[0020] Such as figure 1 As shown, a pneumatic tire (hereinafter simply referred to as "tire") 1 includes: a pair of bead portions 11; a sidewall portion 12 extending from each bead portion 11 outward in the tire radial direction D2; The respective outer ends in the tire radial direction D2 of the side portions 12 are connected to the tread portion 13 having a tread surface 13 a in contact with the ground on the outer side in the tire radial direction D2 . In addition, the tire 1 is attached to a rim (not shown).

[0021] In each figure, the first direction D1 is: the tire axial direction D1 parallel to the tire rotation axis, the second direction D2 is: the radial direction of t...

Abstract

The invention provides a pneumatic tire. A plurality of sidewall pattern blocks of the pneumatic tire comprise a first sidewall pattern block arranged on the outer side of a first tread pattern block in the axial direction of the tire; and a second sidewall block disposed on the outer side of the second tread block in the axial direction of the tire, the first sidewall block having a first top surface disposed on the outer end in the axial direction of the tire, the second sidewall block having a second top surface disposed on the outer end in the axial direction of the tire, and the area of the second top surface being larger than the area of the first top surface.

Description

technical field [0001] The present invention relates to a pneumatic tire. Background technique [0002] Conventionally, for example, a tread portion of a pneumatic tire includes a plurality of tread blocks arranged in the tire circumferential direction. In addition, a sidewall portion of a pneumatic tire includes a plurality of sidewall blocks arranged on the outer side of the tread block in the tire axial direction (for example, Patent Document 1). [0003] In the pneumatic tire according to Patent Document 1, the tire axial outer ends of the tread surface of the tread blocks are at the same position, and the shapes of the side blocks are the same. According to this, the rigidity of the buttress portion (the outer end region in the tire radial direction of the sidewall portion) can be made uniform in the tire circumferential direction, but the traction performance cannot be sufficiently improved (for example, the surface of the sidewall block or the The ability of the edg...
