Slime's prevent and repair tire sealant seeks out and instantly seals tread area punctures in tubeless tires up to 1/4 in. When a puncture occurs, our patented sealant is carried directly to the source. The pressure of the escaping air forces the particles into the opening, where they build-up and intertwine to form a long-lasting, flexible plug. Instantly, air loss is blocked and a flat tire is prevented. Install in any of your tubeless non-highway vehicles (including ATVs/UTVs, golf carts, riding lawn mowers, small trailers, tractors, scooters and much more) and enjoy 2 years of continuous flat tire protection.
