This stuff really saves a lot of flats from stopping a ride. I do not ride without it.
In tubeless tires, the Slime Super Duty seal is as effective as a normal repair. In tubed tires, regard Slime in the same way as you would a patch. There is no other product like Slime on the market; there are no glues, no latex, and no adhesives in its formulation. Slime is simply the most innovative breakthrough in flat tire prevention.
Slime Tire Sealant is formulated and tested for use in all pneumatic tires. Once installed, Slime remains liquid and will not harden or dry out. As the Slime treated tire rotates, centrifugal force pushes the sealant to the tread area creating a layer of protection, repairing punctures as they occur and treating existing punctures. Slime is not intended for use in tires losing pressure from sidewall punctures, bead leaks, damaged rims or faulty valves. Slime is recommended as a repair only in high speed, over-the-road tires.
What is Fibro-Seal™ Technology? Slime utilizes a state-of-the-art blend of environmentally-friendly fibers, binders, polymers and proprietary congealing agents which intertwine and clot within the puncture. This Fibro-Seal™ lattice, together with the viscous transportation system (the "green" goo) seeks out and tightly packs itself into the puncture, preventing and repairing flats with a flexible, long lasting plug.
Use note: Slime Super Duty can also be used to install tubeless tires. Slime tire sealant installs between the rim and the tire bead. Hold the bead open with two tire levers, install, and re-inflate with a fast burst of air to seat the bead to the rim.
