As well as standard tyres and inner tubes we also offer a range of "Puncture Resistant" options including:
  • Self healing, Slime filled inner tubes
Slime Tube Sealant is a specially formulated liquid which is injected into the inner tube through the valve.  It prevents and repairs flat tyres caused by sharp objects up to 3mm in diameter. Slime Tube Sealant works repeatedly for up to 2 years.  When a puncture occurs the Sealant moves into the hole and the clotting agents are activated, effectively filling the hole and blocking the loss of air.
Slime Tube Sealant
  • Instantly seals up to 1/8" (3mm) punctures for up to two years
  • Non-toxic, Non-hazardous and Non-flammable
  • Environmentally friendly and cleans up with water
  • Effective under the most extreme temperatures: Low freezing point of -35˚F (-37˚C) and a high separation point of 182˚F (82˚C)
  • Uses Fibro-Seal technology
  • Requires air
If you purchase Slime filled inner tubes from us the Slime will already be inside the inner tubes when you receive them. They can be fitted the same as a standard inner tube.
