Aither is a multi-cell foam compound that forms the structure of the Armour. Review: Extremely Dependable - No better protection for daily commute 5Star Review: So far so good - I purchased one insert as a trial since reviews were mixed as to how easy it would be to fit and what the ride would be like. In the event the fit was easy with my Schwalbe Smart Sam, Active, 2.60 tyres. Riding on the road I noticed no difference; over roots,, etc. it feels more comfortable. I've consequently ordered a second. ## Features - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08P3TTLHR | | Best Sellers Rank | 39,596 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 247 in Tyres (Sports & Outdoors) | | Bike Type | Mountain Bike | | Bike type | Mountain Bike | | Brand | Tannus | | Brand Name | Tannus | | Colour | Red | | Customer Reviews | 4.2 out of 5 stars 407 Reviews | | Included Components | Instructions | | Item Diameter | 26 Inches | | Item Width | 4 Inches | | Item diameter | 26 Inches | | Item width | 4 Inches | | Manufacturer | Tannus | | Manufacturer Part Number | TA Insert | | Material Type | Foam,Rubber | | Model Number | TA Insert | | Number of Items | 1 | | Number of Packs | 1 | | Size | 26" x 4.0-4.8" | | Tread Type | Multi-terrain or All-terrain | | Tyre Type | Clincher | | Tyre type | Clincher | | Unit Count | 1.0 count | | Warranty Type | Limited | | Warranty type | Limited | | Wheel Size | 26 Inches | ## Product Details - **Bike type:** Mountain Bike - **Brand:** Tannus - **Colour:** Red - **Item diameter:** 26 Inches - **Item width:** 4 Inches - **Material:** Foam,Rubber - **Size:** 26" x 4.0-4.8" - **Tyre type:** Clincher - **Warranty type:** Limited - **Wheel size:** 26 Inches ## Images ![Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads - Image 1](https://m.media-amazon.com/images/I/513JWzklj0L.jpg) ![Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads - Image 2](https://m.media-amazon.com/images/I/91eQFVvz5wL.jpg) ![Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads - Image 3](https://m.media-amazon.com/images/I/71H93jpH8OL.jpg) ![Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads - Image 4](https://m.media-amazon.com/images/I/61XO1W+VClL.jpg) ![Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads - Image 5](https://m.media-amazon.com/images/I/61zXD6KdIKL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this work with wtb 650b x 47c road plus tires?** A: They come in all sizes **Q: Will this work on a 700 x 25 tyre?** A: Ahahahahhahaha.. Nope, I had to get therapy after my unfortunate run in with these. If you are getting loads of punctures on a commute then buy solid tyres and have them fitted by your nearest stockist, that or practice repairing punctures as these are not fit for purpose. **Q: Hello my question is whether I can still use the normal inner tube size of whether this has to be adjusted** A: No, you HAVE to use a size smaller inner tube. The liner fills the inner space so a smaller tube is required. **Q: Why are you selling the 26 in fat bike for that price other than greed ? Disgraceful** A: Well I bought it and it works well, fiddly to fit but good once sat correctly. Is expensive though ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extremely Dependable *by S***8 on 4 November 2025* No better protection for daily commute 5Star ### ⭐⭐⭐⭐⭐ So far so good *by A***R on 9 October 2020* I purchased one insert as a trial since reviews were mixed as to how easy it would be to fit and what the ride would be like.
