The insert has an inner diameter surface sized to fit snuggly about a periphery of a tire rim and an outer diameter sized to fit within a tire cavity. The insert is spaced from the tire inner casing surface during normal operation and supports the tire inner casing surface away from the rim in the event of a flat tire. A molding apparatus and a method of forming a run-flat tire insert is also disclosed.
