The Tube With Tubeless Flat Protection

Tired of flat tires? If you ride in an area where the roads are often covered with glass, wire, or small thorns, Slime Self-Sealing Tubes may be for you. The butyl rubber tube is filled with green colored "Slime" sealant. The sealant seeps out any small hole and solidifies to seal the hole as you're riding. You often won't even know you had a flat.


  • Schrader Valve
  • Pre-filled with Slime sealant
  • Sizes for 16", 20", 24", 26" and 29" tires
