Tire vulcanization mold and pneumatic tire

Abstract

A tire vulcanization mold including a sector mold divided into a plurality of pieces along a circumferential direction of a green tire, the sector mold configured to vulcanization mold a tread portion of the green tire into a predetermined shape, and an upper mold and a lower mold disposed on both sides of the green tire so as to sandwich the green tire therebetween in an axial direction of the green tire, the upper mold and the lower mold configured to vulcanization mold a side portion of the green tire into a predetermined shape. The sector mold has a relief groove in a vicinity of a fitting portion between the sector mold, and the upper mold and the lower mold.

What is claimed is: 
     
         1 . A pneumatic tire comprising:
 a protrusion-shaped mold fitting mark located between a tread portion and a side portion; and   a protrusion-shaped molding mark provided in a vicinity of and outside on the mold fitting mark,   wherein the molding mark is a plurality of protrusions in a mesh shape extending in a direction intersecting with both a circumferential direction and a radial direction.   
     
     
         2 . The pneumatic tire according to  claim 1 , wherein the molding mark has a height of 0.3 mm or more and 0.5 mm or less. 
     
     
         3 . The pneumatic tire according to  claim 1 , wherein the molding mark is provided away from the mold fitting mark by a distance of 0.5 mm or more and 0.8 mm or less. 
     
     
         4 . The pneumatic tire according to  claim 2 , wherein the molding mark is provided away from the mold fitting mark by a distance of 0.5 mm or more and 0.8 mm or less. 
     
     
         5 . The pneumatic tire according to  claim 1 ,
 wherein a lug groove is provided on an outer surface of the pneumatic tire, and   wherein the molding mark is provided away from the lug by a distance of 0.5 mm or more and 0.8 mm or less.   
     
     
         6 . The pneumatic tire according to  claim 2 ,
 wherein a lug groove is provided on an outer surface of the pneumatic tire, and   wherein the molding mark is provided away from the lug by a distance of 0.5 mm or more and 0.8 mm or less.   
     
     
         7 . The pneumatic tire according to  claim 3 ,
 wherein a lug groove is provided on an outer surface of the pneumatic tire, and   wherein the molding mark is provided away from the lug by a distance of 0.5 mm or more and 0.8 mm or less.   
     
     
         8 . The pneumatic tire according to  claim 4 ,
 wherein a lug groove is provided on an outer surface of the pneumatic tire, and   wherein the molding mark is provided away from the lug by a distance of 0.5 mm or more and 0.8 mm or less.   
     
     
         9 . A pneumatic tire comprising:
 a protrusion-shaped mold fitting mark located between a tread portion and a side portion; and   a protrusion-shaped molding mark provided in a vicinity of and outside on the molding mark,   wherein the molding mark is provided away from the mold fitting mark by a distance of 0.5 mm or more and 0.8 mm or less, and   wherein the molding mark is a protrusion extending annually in a tire circumferential direction.
