NO FLATS, MAXIMUM PROTECTION: Tannus Armour tire insert works as a puncture-proof tire liner and bike tube protector, helping stop flats from thorns, goatheads, rocks, and debris while improving comfort on fat tire, gravel, and e-bike rides
PATENTED AITHER FOAM TECHNOLOGY: Made from lightweight, high-tech multi-cell foam, this insert provides 15mm of top protection and sidewall support, delivering vibration dampening, better grip, and a smoother, quieter ride
RUN-FLAT CAPABILITY & PINCH-FLAT DEFENSE: Ride with confidence knowing your tires gain run-flat support in case of a puncture and added protection against pinch flats, helping you finish your ride even with low or no air
BETTER HANDLING THAN SOLID LINERS: Unlike solid rubber tire liners, Tannus Armour tire insert improves ride feel, control, and stability, supporting your bike tire and tube across different pressures while maintaining comfort, grip, and low rolling resistance for mountain, gravel, fat tire, and e-bike riding
FAST, TOOL-FREE INSTALL: This Tannus Armour tire insert installs easily between your bike tire and inner tube in about 10–15 minutes per wheel, with no special tools required—simple to remove and reuse when changing mountain, gravel, fat tire, or e-bike tires and tubes

The effective all-round protection for bicycle tires against punctures, cuts and bruises!
Up to 15 mm thick at the thickest point, 3-5 mm on the sides and 2 mm in the rim area.
Compatible with the majority of bike tires.
Very light, reusable and recyclable.
Even at low air pressure, the Armour counteracts deformation and maintains a high level of grip.
Ride with a flat: Even with a flat or defective tube you can continue riding at a reduced speed of 5 MPH.
