Does your tire have a tube inside, or is it tubeless? Who cares?! Slime's new 2-in-1 Tire & Tube Premium Sealant works to prevent and repair flats in all off-highway tires and tubes. It just works! Slime's 2-in-1 Tire & Tube Premium Sealant seeks out and instantly seals tread area punctures up to a 1/4" in tires and up to 1/8" in tubes. When a puncture occurs, Slime's 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 tube or tubeless non-highway vehicles (including ATVs/UTVs, golf carts, riding lawn mowers, small trailers, tractors, scooters, bicycles, dirt bikes and much more) and enjoy two years of continuous flat tire protection. No more flats!
