Slime 1-gallon Tire Sealant is a ready-to-use, eco-friendly liquid that prevents and instantly seals tubeless tread punctures up to 1/4" (6mm) in off-highway tires.

Designed for non-highway vehicles and equipment, this Slime formula uses Fibro-Seal Technology to locate punctures and create flexible plugs from within the tire. The product ships in a one-gallon jug and is non-toxic, water-soluble, and non-flammable, making it suitable for seasonal storage and routine maintenance. It is formulated to work with an air source and remains effective for up to two years when applied correctly.

How does Slime seal punctures without dismounting the tire?

When a puncture occurs, escaping air drives the sealant particles directly into the opening. Those particles interlock and form a durable, flexible plug that blocks air loss in the tread area without the need to remove the tire.

  • Fibro-Seal particles carried by airflow to the puncture site
  • Forms an internal, flexible plug for lasting repair
  • Designed specifically for tubeless tread-area cuts and punctures up to 1/4" (6mm)
  • Works immediately at the moment of puncture to stop most slow leaks

Which vehicles and tires are compatible with this sealant?

This jug is formulated for off-highway tubeless tires where highway speed rating or DOT compliance is not required. It is widely used across light equipment and recreational vehicles that frequently experience small punctures from nails, screws, or thorns.

  • Golf carts, riding lawn mowers, ATVs and UTVs
  • Small trailers and trailers' tubeless tires
  • Tractors, garden equipment, and scooters used off-highway
  • Not intended for highway or DOT-rated passenger car tires

How do I apply Slime 1-gallon sealant and maintain it over time?

Application is straightforward: add the correct volume to the tire and inflate using a standard air source. After initial fill, check tire pressure periodically and top up sealant as needed; properly applied sealant can protect tires for up to two years.

  • Determine recommended volume based on wheel size or manufacturer guidance
  • Pour sealant into the valve or through a removable valve core with an injector
  • Inflate tire to proper pressure and rotate or drive a short distance to distribute sealant
  • Inspect periodically and replace every two years or if severely contaminated

Is this sealant safe for rims, air valves, and the environment?

Slime’s formulation is non-toxic, non-corrosive, non-hazardous and water-soluble, reducing risk to rims and allowing easier cleanup than solvent-based alternatives. It is non-flammable and designed to be safe for regular tire maintenance when used as directed.

  • Non-corrosive to most rim materials and valve components
  • Water-soluble for easier cleanup during tire service
  • Non-toxic and non-hazardous for safer handling and storage
  • Store in original container away from extreme heat or freezing

Who is this product for? Slime 1 Gallon Off-Highway Tire Sealant is ideal for property owners, landscapers, fleet managers, and outdoor enthusiasts who want a durable, low-maintenance solution to prevent and repair tread-area punctures on tubeless, off-highway tires. If you operate golf course equipment, riding mowers, garden tractors, small trailers, scooters, or recreational off-road vehicles and need reliable puncture protection without frequent dismounts, this product provides a practical, eco-friendlier option for ongoing tire care.
