Tannus Armour Tire Insert - 24 x 1.95-2.5 | Single
Is the Tannus Armour Tire Insert 24 x 1.95-2.5 the right flat protection for your 24-inch youth or cargo bike?
The Tannus Armour Tire Insert 24 x 1.95-2.5 is a foam insert that sits between your tire and inner tube to deliver puncture protection, pinch-flat protection, and rim protection on 24-inch wheels in the 1.95 to 2.5 inch width range. Built around Aither, Tannus's patented multi-cell rebounding foam compound, the insert provides 15mm of puncture protection under the tread and 2mm of sidewall protection from sharp objects, eliminating roughly 90% of common flats. This is the right insert for 24-inch youth bikes, smaller-frame mountain bikes, and 24-inch cargo bikes where flat reliability matters every ride.
Armour also lets you run lower tire pressures for better grip and a smoother ride without risking pinch flats, and it provides run-flat capability so a puncture does not end your ride immediately. Installation is as simple as a regular tube swap, requires a minimum 19mm inner rim width, and uses a smaller-than-stock tube (24 x 1.5-1.95) for proper fit. Sold as a single insert, weight 270g, in Tannus's signature red.
