Abstract: A rubber composition having a good reinforcing property and a remarkably improved resistance against heat build-up is disclosed, which comprises 100 parts by weight of at least one of natural rubber and synthetic rubber and 20-200 parts by weight of furnace carbon black having a specific surface area of 85-95 m.sup.2 /g, a dibutyl phthalate absorption value of 100-110 ml/100 g and a tinting strength of 95-105.

Abstract: A rubber composition comprising a rubber containing a polymer of ethylene-propylene copolymer or ethylene-propylene-diene terpolymer, polybutene and an inorganic filler has an excellent puncture-sealing property. Tubeless tires provided with the rubber composition have a high resistance against the puncture.
