PROBLEM TO BE SOLVED: To provide a mold release agent for a tire inner surface having excellent releasability between a raw tire inner surface and a bladder, and a tire where the mold release agent for a tire inner surface is hardly released from the tire inner surface.SOLUTION: A mold release agent for a tire inner surface contains fired kaolin having an oil absorption amount of 50 ml/100 g or more. It preferably contains further a silicone component, a surfactant and water. It is preferable that the weight percentage of the fired kaolin is 10 to 90 wt.%, the weight percentage of the silicone component is 10 to 75 wt.% and the weight percentage of the surfactant is 1 to 20 wt.% based on the total amount of the fired kaolin, the silicone component and the surfactant.SELECTED DRAWING: None |
