  "textContent": "It is to provide a rubber composition providing a large friction force even on a body having, for example, an ice face of a low friction coefficient by constituting with a foamed rubber having a rationalized foaming state, and a pneumatic tire, particularly a winter-seasoned tire such as a studless tire having improved steering stability performances such as braking performance, cornering performance and the like by applying this rubber composition to an upper-layer rubber part of a tread rubber constituting at least a ground contact face to enhance a gripping force on a frozen road surface or a snow covered road surface as well as a method of producing such a tire. A rubber composition 1 of this invention constituted with a foamed rubber, characterized in that the foamed rubber has continuous cells 6 each continuously extending substantially along a particular direction 4 and sealed with a resin protection membrane 5.",
