A low pressure tire including a torus of flexible, substantially inelastic material. The material will not deform at a temperature of about 225.degree. F. The torus includes an inner diameter surface for engaging a tire supporting rim and an outer diameter surface for contacting a support surface. The torus can flatten under a load to facilitate movement of the tire over soft or irregular support surfaces. A sealable opening permits the inflation and deflation of the torus.
