Abstract
To provide a pneumatic tire capable of improving the durability of connection points between partition wall parts and a tire inside surface. In a pneumatic tire, partition wall partsthat extend inward in a tire radial direction from a tire inside surfaceof tire shoulder partsand whose tire radial direction inside ends contact a rimare disposed. A pair of right and left reinforcement layersare disposed in regions ranging from the partition wall partsto tire side partsvia connection partsbetween the partition wall partsand the tire inside surfacesuch that the reinforcement layerscontinue from the partition wall partsto the tire side partsvia the connection partsbetween the partition wall partsand the tire inside surface. Because of the reinforcement layers, the portion of each of the connection partsbetween the partition wall partsand the tire inside surfacewhere a first carcass plyis disposed and the portion thereof where a second carcass plyis disposed can be prevented from separating, whereby the durability of the connection partsof the partition wall partscan be improved in comparison to what has conventionally been the case.
