An elastomeric tire with arch shaped shoulders for mounting onto a rim that is manufactured by spin casting or molding methods that includes an annular cavity that is centered under the tire tread having equal thicknesses of side walls and an area under the tread whose slope outwardly into shoulder that the side walls upper ends intersect that have greater thickness and which side walls lower ends include beads that are each spaced a selected distance from the surfaces of the side wall ends that slope upwardly from inner to outer surfaces and with the tire preferably including plies that extend across the tire having ends that wrap around the beads and belts fitted around the tire circumference, above the plies, and including porous spacers fitted between the layers of plies and belts to pass a flow of the elastomeric material therethrough during tire formation.
