摘要

A multi-chambered tire assembly (10) is provided by a pneumatic outer tire (12) mounted upon a rim (16) of a wheel and having an inner tire (14) or shield which is also mounted upon the rim (16). The inner tire (14) has a crown portion (36) spaced from the outer tire and a pair of sidewalls (38) each extending from the crown to a bead portion (40, 42). At least one of the bead portions (42) of the inner tire (14) forms an air passage way (44) between it and the adjacent bead (22) of the outer tire and is provided with radially extending grooves (52) connecting the air passage way with the outer air chamber (32).
