Description
Air-Liner Tubeless Tire Insert System
Engineered for All-Terrain Confidence
Precision-crafted foam inserts replace inner tubes in tubeless-ready tires (26″-29″ sizes), delivering triple-layer protection against rim damage, trail debris, and sudden deflations. Ideal for mountain bikers tackling rocky descents (max 2.4″ tire width) or commuters navigating pothole-heavy routes, our system maintains structural integrity even after punctures.
Key Performance Advantages
✔️ 40% Lower Pressure Threshold: Safely run 15-25% reduced PSI for superior traction without bead detachment risks
✔️ Self-Repairing Technology: Integrated micro-pores seal 90% of punctures under 2mm automatically
✔️ Run-Flat Assurance: Maintain 50%+ load capacity for 30+ miles after total air loss
✔️ Ammonia-Free Design: Works seamlessly with popular sealants (Slime/Orange Seal compatible)
Smart Application Scenarios
• Enduro racers needing consistent cornering grip at 20PSI
• Adventure cyclists carrying emergency repair kits in minimalist setups
