An air spring rolling-lobe flexible member, which is made of elastomeric material, has a reinforcement arrangement which is embedded in the flexible member wall (1). The reinforcement arrangement extends along the entire length of the flexible member and is of rubber-coated cord fabric layers (3, 4). The flexible member has a non-symmetric reinforcement arrangement wherein the one outer fabric layer (3) or the several outer fabric layers has/have a stress-elongation characteristic which is different from that of the one inner fabric layer (4) or the several inner fabric layers.
