An elastomeric tire for mounting onto a rim that is manufactured by casting or molding methods to include an exterior arch shaped cavity that is centered under and is below the tire tread to have at least one hundred forty (140) degrees and not more than one hundred seventy (170) degrees of arc from one tire rim mounting contact point, around the tire to another tire rim mounting contact point, and with the cavity arch duplicated around the tire interior. A uniform tire wall thickness is provided that is selected for a particular anticipated load as the tire will carry, with the tire side wall ends each maintained at one the rim opposing ends, supporting the load carried by the tire in compression, and with the tire, at atmospheric pressure, providing ride and wear characteristics that are comparable to a pressurized pneumatic tire carrying a like load, and which tire of the invention interior arch-shaped cavity can be pressurized to add to its inherent load supporting character to safely support even greater loads.
