- 110mm: Fits ~4.5"–5.0" wide tires
🛠️ Installation steps
- Prep: Deflate and remove the wheel. Unseat one bead and take out the tube. Wipe the inside of the tire to remove dust and debris.
- Dry fit: Wrap the liner around the inside circumference to confirm length and width alignment.
- Adhesive apply: Peel a small section of backing and start at the valve area. Press the liner firmly as you progress, peeling backing gradually.
- Smooth it: Ensure there are no overlaps, bubbles, or sharp edges. Trim excess cleanly if needed.
- Reinstall: Place the tube, seat the bead evenly, inflate slowly, and check for uniform seating.
- Test ride: Roll a short distance and verify the tire runs true without rub or noise.
Maintenance & care
- Periodic checks: At rotation or after rough rides, deflate partially and feel for any liner edges or bunching.
- Clean surfaces: Keep the interior free of sand and grit that can undermine adhesion.
- Pressure discipline: Run pressures appropriate for your tire size and terrain to reduce pinch risks.
- Replace when worn: If you notice cuts or lifted sections, replace the liner to maintain protection.
Troubleshooting
- Wrinkles or rub: Liner may be too wide. Move down a width or re-seat carefully, trimming excess.
- Poor adhesion: Clean the casing with isopropyl alcohol, dry fully, and reapply with firm pressure.
- Persistent flats: Inspect tread for embedded objects, check rim tape for spoke holes, and verify correct tire pressure.
- Noise while riding: Look for a lifted edge near the bead; deflate, smooth the liner, and re-seat the bead evenly.

FAQ
Do these work with tubeless setups?
They’re primarily designed for tubed configurations. If you’re running tubeless, rely on proper sealant, casing protection, and inserts engineered for tubeless systems.
Will they affect cornering or traction?
Installed smoothly and sized correctly, most riders won’t notice a difference. The liner sits inside the casing and doesn’t change tread or compound.
How long do they last?
Longevity depends on terrain and mileage. Inspect periodically; replace if you see cuts, lifted edges, or loss of adhesion.
How do I choose the right width?
Match the liner width to your tire’s interior width. As a general guide: ~54mm for 2.4–3.0", ~80mm for 3.5–4.0", ~110mm for 4.5–5.0".
Can I stack liners for more protection?
Stacking isn’t recommended; it increases weight and can cause fit issues. If you need more protection, consider tougher casings or foam inserts designed for your tire type.
