It is a subject to provide a method for manufacturing a tire rubber member and a pneumatic tire using the same capable of improving productivity and of accurately finishing sectional shapes. The method includes: a step of fixedly attaching winding start points 8 As, 8 Bs of a first rubber strip 8 A and a second rubber strip 8 B at positions located further inside in a width direction than respective sides e 1 , e 2 of a rubber member R; a first winding step of forming a first layer 10 by spirally winding the first rubber strip 8 A towards the one side e 1 and the second rubber strip 8 B towards the other side e 2 up to the respective sides e 1 , e 2 ; a second winding step of respectively turning the first rubber strip 8 A up at the one side e 1 and the second rubber strip 8 B at the other side e 2 so as to successively form a second layer 11 outside of the first layer 10 ; and a step of fixedly attaching a winding end point 8 Af of the first rubber strip and a winding end point 8 f of the second rubber strip to positions further inside in the width direction than the respective sides e 1 , e 2.
