Abstract:
1. A method of manufacturing a pneumatic tire having an innerliner formed of thermoplastic elastomer, comprising the steps of: heating a surface of a tire building drum in advance; placing the innerliner on the heated surface of the tire building drum, the innerliner having a thickness of 80 μm to 300 μm and being cylindrically shaped and having a radially outer surface to which an adhesive has been applied; disposing uncured tire components radially outwardly of the innerliner to form a green tire; and curing the green tire, wherein the adhesive has a glass transition temperature ranged from −20° C. to 30° C., wherein the surface of the tire building drum is heated at a temperature of 40° C. to 60° C. in the step of heating the tire building drum, wherein the heating is carried out at least until the uncured tire components are applied to and radially outward of the innerliner, and wherein by placing the adhesive in a higher tackiness condition through the heating, than the tackiness condition prior to heating, the uncured tire components are attached to the innerliner.
