Yes, that is my point. It should not have failed. I followed the directions exactly.
One detail I left out was the other fun experience I had when I tried to disconnect the hose from the tire. I waited until I thought there would be no pressure, but as soon as I removed the hose from the tire, the sealant squirted all over the place, including onto my car and wheel and back window! Fortunately, I was able to wipe it off quickly, so I don't think it damaged the paint at all. When I got my car back after the tire replacement I cleaned it off more thoroughly. However, taking care of that initial mess was not very much fun in 8 degree F. coldness!!
