Patent ID: 7060145

Claim:
A method of making a pneumatic tire, the pneumatic tire comprising a tire main body and a tread rubber with axial edges, the inside diameter of the tread rubber being smaller at the axial edges than in the intermediate portion therebetween, the tire main body including an underlying component on which the axial edge of the tread rubber is stuck, the method comprising making a green tire and vulcanizing the green tire, the making of the green tire comprising making an assembly of an annular raw tread rubber and a tread reinforcing belt, making a raw tire main body including an underlying component, placing the assembly of the annular raw tread rubber and the belt around the raw tire main body, swelling the raw tire main body by pressurizing the inside thereof so that a crown of a swollen part thereof presses a central part of the inner surface of the assembly, pushing the entire width of the raw tread rubber onto the swollen tire main body partially with respect to the tire circumferential direction by relatively moving a presser roller toward the swollen part to a sticking position, the sticking position being such that the presser roller pushes the swollen part together with the assembly so that beneath the presser roller the swollen part changes its shape and the overall width of the inner surface of the assembly closely contacts with the tire main body, whereby the axial edges of the tread rubber adhere to the underlying component, wherein a part of the presser roller contacting with the assembly has a profile which is substantially the same as a profile of the assembly, and conducting the circumferentially-partial pushing through the entire circumference of the raw tread rubber by relatively moving the presser roller around the assembly while maintaining the sticking position, whereby the axial edge of the raw tread rubber is stuck on the underlying component.
