FAQ

Which tires will this Armour insert fit?: This Armour fits 24 x 3.0-4.0 inch tires (ISO 507x75-100). It is sized for 24-inch fat tire kids bikes, mid-tail cargo e-bikes, and similar fat tire 24-inch wheel builds.

What tube size do I need with this Armour?: You need a 24 x 2.5-3.0 inch inner tube, which is one size smaller than the tire. Tannus Armour displaces space inside the tire, so a properly downsized tube is required for correct fit.

Does this fat tire Armour have run-flat capability?: No. Fat tire sizes (20x3.0-4.0, 20x4.1-4.8, 24x3.0-4.0, 26x4.0-4.8) do not have run-flat capability. You will still get full 15mm puncture protection and pinch-flat protection while riding, but a flat will end the ride.

What is Aither and what protection does it provide?: Aither is Tannus's patented multi-cell rebounding foam compound. It provides 15mm of puncture protection under the tread and 2mm of sidewall protection, eliminating roughly 90% of common flats while still letting the tire roll and absorb bumps normally.

Best For

Riders on 24-inch fat tire kids bikes, mid-tail cargo e-bikes, or fat tire cargo e-bikes running tires in the 3.0 to 4.0 inch width range who want maximum puncture protection, pinch-flat defense, and rim protection in a simple tubed setup.
