Abstract: PURPOSE:To increase the low heating property without sacrificing wear- resistance and fracture-resistance by providing a specified volume ratio of a base tread rubber to a cap tread rubber, mixing carbon with a specified grain size, N2SA value, and parts by weight, and containing a specified SPB and others. CONSTITUTION:The volume ratio of a base tread rubber 4 of a tire which is formed by arranging a belt layer 2 at the head part of a steel carcass layer 1 and putting a cap/base tread 3 on it to a cap tread rubber 5 is set at 80/20 to 20/80. Also the base tread rubber 4 contains a carbon with a grain diameter of 70m /g or more in N2SA value by 30 to 55 part by weight and a syndiotactic-1, 2-polybutadien of 130 to 180 deg.C in melting point by 1 to 30 part by weight. Thus the life against wear is prolonged, and the cut of a tread part and the burst of a tread pattern block becomes rarely to be produced at low heating.

Abstract: 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.
