No more flats! Slime's Prevent & Repair Tire Sealant seeks out and instantly seals tread area punctures in tubeless tires up to 1/4" (6mm). 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 two years of continuous flat tire protection. • Instantly seals up to 1/4" (6mm) punctures • Seals punctures for up to 2 years • Stops slow leaks • Safe and easy • Great for preventing flat tires in: ATVs/UTVs, golf carts, riding lawn mowers, small trailers, tractors, scooters and all other non-highway tubeless tires
