Tube Sealant. While my flat resistant tires work well, some road debris like the thin steal wires from ruptured automobile steal belted radial tires still manage to puncture them. Subsequently, I still need another level of protection if I want to accomplish my mission to eliminate flat tires forever. Fortunately, I found that I could do that with tube sealant.
I had heard horror stories about sealant, however, this was not the case for me. For example, in one instance I was turning at an intersection when I heard the pssst . . . . pssst . . . . pssst . . . . of a punctured tire going flat. Yet, before I cleared the intersection the tube sealant had already sealed the puncture. All I had to do was pump a little air into the tube to replace what was lost and I was on my way.
Since most tube sealant only requires a few ounces in each tube, there is negligible weight added to my wheels. But most of all, it’s very satisfying to hear a flat tire just fix itself.
