A safety liner ( 20 ) for a vehicle tire ( 500 ) includes a tubular body ( 22 ) having a one-way valve ( 24 ). A service valve ( 50 ) is selectively insertable into the one-way valve ( 24 ). Tubular body ( 22 ) is compressible into a flattened circular shape by a compressive force, and when the compressive force is removed, the tubular body ( 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 of vehicle tire ( 500 ) to be retained at a reduced profile.
