The needle (12) of the device for inserting a wire into a tire has: a piercing zone (18) having an axis of symmetry, and a duct (30) having a proximal opening and a distal opening (36) opening into the zone (18) and off-center relative to the axis, the duct consisting of the proximal opening and of a rectilinear profiled section including the distal opening.

The present invention provides a rubber composition that may improve fracture resistance of the resulting tire while maintaining good drainage performance, and a tire using the same. The rubber composition includes: a rubber component; and a fiber made of a hydrophilic resin. The fiber is formed with a coating layer on its surface. The coating layer is made of a resin having affinity for the rubber component.
