<p><P>PROBLEM TO BE SOLVED: To provide a tire inner surface releasing agent having good dispersion stability with the lapse of time and becoming sufficiently transparent when attached to a green tire inner surface and vulcanized. <P>SOLUTION: This tire inner surface releasing agent includes an inorganic component comprising powder; a silicone component; a surfactant; a polyhydric alcohol; and water. The boiling point of the polyhydric alcohol is 200°C or more. The weight ratio of the total amount of the polyhydric alcohol and the water is 35 to 90 wt.% of a tire inner surface releasing agent. Preferably, the polyhydric alcohol is 10 to 60 wt.% of a total amount of the polyhydric alcohol and the water. The tire is obtained by attaching this tire inner surface releasing agent to an inner surface of a green tire and by performing vulcanization. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
