Abstract: A safety liner (20) for a vehicle tire (500) includes a toroidal tube (22) having at least one hole (24). At least one plug (26) is selectively insertable into the at least one hole (24). Toroidal tube (22) is compressible into a flattened circular shape by a compressive force, and when the compressive force is removed, the toroidal tube (22) resiliently assumes its original toroidal shape. Safety liner (20) is installed in the cavity (503) of vehicle tire (500) as the vehicle tire (500) is being installed on the tire rim (502). If a blowout or other leak occurs, safety liner (20) will cause the shape and pressure of vehicle tire (500) to be retained for a period of time.
