PROBLEM TO BE SOLVED: To provide a foamed elastic filler satisfying both of the settling resistance and steering stability at off-road, and a tire for two-wheeled vehicles produced by using the filler, especially a tire for two-wheeled motor vehicles for on-road use as well as off-road use. SOLUTION: The foamed elastic filler is produced by compounding 100 pts. wt. of a rubber component composed mainly of a butyl rubber and/or a halogenated butyl rubber with 0.3-2.0 pts. wt. of a sulfur-based vulcanizing agent and 0.3-3.0 pts. wt. of a vulcanizing agent for forming a monosulfide bond and/or 0.3-3.0 pts. wt. of a post-vulcanization agent and has an apparent specific gravity of 0.08-0.2. The tire for two-wheeled vehicles is produced by using the foamed elastic filler 3 pressed in a manner to fill a doughnut-shaped space formed between a rim 2 and a tire shell 1.
