Say goodbye to mid-ride flats and hello to carefree cruising on Iowa’s gnarliest gravel or your neighborhood greenbelt. The Tannus Armour 26 × 4.0 Tire Insert slips between your tube and fat-tire, wrapping it in a 360° multi-cell foam “helmet” that blocks thorns, glass, goat-heads, and rim-pinch impacts—so you can ride harder, run lower PSI, and still make it back for tacos.
Why Riders Love It
-
Stops 90 % of punctures with 15 mm of impact-absorbing Armour under the tread and 2–5 mm on the sidewalls — no more cactus spikes or pinch flats ruining your day.
-
E-bike ready. The proprietary compound is torque-tested to handle high-powered motors and the extra weight of fat-tire e-bikes.
-
Ride softer, grip harder. Lower your tire pressure for extra traction and silky comfort without risking snake-bites or rim dents.
-
Rim-saving cushion. Armour eats up rock strikes, protecting expensive wheels on rough single-track or curb hops.
-
DIY-friendly install. Pops in with standard tire levers—no sealant mess, no special tools. (Tip: a quick spritz of soapy water makes it effortless.
