Tannus Armour Fat Tire Inserts deliver 15mm of top puncture protection and 2mm of sidewall defense using patented Aither Technology—a multi-cell foam compound built for real-world abuse. Whether you're pushing off-grid trails or grinding through rocky terrain, this insert keeps you rolling. Built-to-perform and field-tested, it pairs a Schrader-valve tube with the foam structure in one package. Fits 24-inch and 26-inch fat wheels from 4.0 to 4.8 inches. Single insert—grab two for a full set. We vetted this one because it does exactly what it promises.
Scroll through Amazon and you will find tire inserts wrapped in five-star reviews for products that do not even match the listing. At Volt Trek, we vetted Tannus Armour because their patented Aither multi-cell foam actually performs on real trails, not just in marketing photos. We test what we sell — if we would not ride it on our own garage builds, we do not list it. The 15mm top protection and 2mm sidewall defense speak for themselves: thorns, glass, and pinch flats stop being your problem. This insert is built-to-perform, and every claim is backed by the Aither compound itself, not hype.
The core of Tannus Armour is not rubber, not foam you find in packaging — it is Aither, a patented multi-cell foam compound engineered specifically for tire inserts. Each cell compresses independently under impact, dispersing force across the entire structure instead of concentrating it on one weak point. That is what gives you 15mm of defense on top and 2mm along the sidewall without turning your ride into a sluggish slog. Whether you are hitting rocky descents or cruising through thorny backcountry paths, the Aither compound keeps the insert working silently until you forget it is even there. Sized for fat tires from 4.0 to 4.8 inches across 24-inch and 26-inch wheels.
Each package arrives with exactly what you need: one Tannus Armour insert sized for your fat tire and one inner tube fitted with a Schrader valve. No hunting for compatible tubes, no guessing whether the insert matches your rim. Available in 24x4, 24x4.8, 26x4, and 26x4.8 sizes, you pick the spec that matches your wheel and the rest is handled. Keep in mind this is a single insert — grab two if you are outfitting both wheels. For riders who treat their ebike as an off-grid machine rather than a fair-weather commuter, this is the kind of detail work that separates a ride you trust from one you worry about.
Confirm your wheel and tire specs before ordering. This insert is sized for fat bike setups only.
From weekend trail rides to daily commuters on fat bikes, Tannus Armour eliminates the flat tire anxiety.
