Beschreibung
Zusammenfassung:	A tube (42) comprising a rubber composition comprising a diene based rubber, from 0.25 to 5 parts by weight, per 100 parts by weight of rubber (phr), of a self-lubrication agent capable of migrating from the rubber composition to surface of the tube and disposing on the tube surface as a liquid, and from 1 to 15 parts by weight, per 100 parts by weight of rubber (phr), of a vulcanization modifier including at least one of ±,É-bis(N,N'-dihydrocarbylthiocarbamamoyldithio)alkanes, bismaleimides, and biscitraconimides is disclosed. Also, a self-inflating tire (12) is disclosed having a tire cavity (28), first and second sidewalls (30) extending respectively from first and second tire bead regions (40) to a tire tread region, and a sidewall groove (136). The tube (42) is positioned within the sidewall groove (136) as an air tube and in contacting engagement with opposite groove surfaces (136, 138) at least partially surrounding the air tube (42).
