A pneumatic spring (10) including a top load transfer member (20), a spaced apart bottom load transfer member (30), and a side wall (40) extending between the top and bottom load transfer members (20, 30). The side wall (40) is formed from a flexible unreinforced monolithic sheet or web of elastomeric material (48). The web (48) of the side wall (40) forms a plurality of convolutions (50) having a minor diameter in the longitudinal direction of the spring and a major diameter in the transverse direction of the spring (10). A plurality of circular hoops (60) extend around the side wall (40). Each hoop (60) is respectively located between an adjacent pair of convolutions (50). A helical coil spring stabilizer (70, 90) is attached to the side wall (40) by a plurality of ligatures (80). The stabilizer (70, 90) is adapted to engage the top load transfer member (20) and the bottom load transfer member (30) at opposite ends of the spring stabilizer (70, 90).
