Abstract: Improved tires designed for use in an improved tire/vehicle system having two pneumatic front tires and two pneumatic rear tires are especially effective when utilized on vehicles with a suspension system having limited camber, as in a live axle suspension system. The tires include a support member which is molded to the inboard sidewall of one or more tires in the tire/vehicle system. The inboard sidewall of a tire provides improved lateral stiffness in the tire, for cornering, and functions similar to cambering in tire/vehicle systems where cambering is not possible or where camber adjustment is limited.

Abstract: 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).
