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.
