PURPOSE: To provide a tire vulcanizing mold eliminating cracks of a tire shoulder section and manufacturing a good tire. CONSTITUTION: In a tire vulcanzing mold of split mold type, the length of a virtual line S connecting respectively a narrowest width section A where the interval of inner faces 27 each other is smallest in the vicinity of the inner faces 27 of both side molds 22 in the tire width direction section with a narrowest width section B where the interval of bead lines 29 of both side molds 22 is set as L, and also the maximum value of the length of virtual lines is set as D when the virtual lines are formed from the virtual lines S to the inner faces 27 of respective side molds 22 in a manner of forming the vertical lines orthogonally to the virtual lines S. The ratio D/L between the maximum value D and the length L is set respectively as 0.15 or less. |
