To provide a manufacturing method of a rubber member for a tire in which remained air upon molding is suppressed and which is applicable sufficiently even in a case of using a rubber composition of low adhesiveness like LRR-blending etc., and a pneumatic tire.
In a manufacturing method of a strip-like rubber member for a tire which is wound spirally over a drum after being conveyed on a conveyor belt, on the surface of a rubber member for a tire being conveyed on a conveyor belt, grooves are formed by using a grooving roller 1 in which plural convex strips 2 extending in the width direction are formed with a specified interval in the circular direction and a convex strip 3 of a specified width that encircles in the circular direction at the central part in the width direction is formed.
