Abstract
Abstract A method of manufacturing a pneumatic tire which when inflated has dimensions generally associated with a conventional pneumatic tire but when deflated has an outer diameter and a section width substantially the same, and in any event not substantially greater, than the maximum width and diameter of the rim on which the tire is mounted. The tire is built by the flat band method of construction and is molded at least substantially in the cylindrical shape in which it was built. The sidewalls are sufficiently flexible that they may be folded into an S-shape and underneath the tread when the tire is deflated.
