No more flats! Slime's Emergency Tyre Sealant seeks out and instantly seals tread area punctures in automotive Tyres up to 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 Tyre is prevented. Install in any of your highway vehicles (including cars, trucks, SUVs, RVs, trailers and much more) when you get an emergency flat Tyre to get back on the road quickly and safely.
