I have never had a single problem with going over anything. obviously within reason of course... Review: Great Quality Tire Protection (2nd review) - I am changing this back to a Great 5 star review because this is a great quality product and Tannus shouldn't be criticized because they didn't do anything wrong, as it was an desertcart issue. Also these 26x4 are not easy to install but after having these professionally installed at a Specialized bike shop by a Specialized bike mechanic which costed an additional $195 on my electric bike the bike rides nicer and smoother then ever and so far NO FLAT TIRES... Thanks again for the High quality bike parts Tannus... ## Features - STOP BUYING & PATCHING TUBES: Our patented foam insert is engineered to stop punctures while improving the comfort of your ride. - TRUSTED BY PROS: Professional MTB teams use Tannus Armour to ride harder without fear of pinch flats or thorn punctures. - NEVER GET STRANDED: Our inserts convert your tires to run flat so you can finish your ride regardless of having air in your tube. - BETTER HANDLING THAN SOLID RUBBER: Our armour IMPROVES your ride handling unlike solid rubber tyre replacements. - FAST, EASY INSTALL: Average installation time is 10-15 minutes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08P3TTLHR | | Bike Type | Mountain Bike , Road Bike | | Brand | Tannus | | Brand Name | Tannus | | Customer Reviews | 4.2 out of 5 stars 299 Reviews | | Item Diameter | 26 Inches | | Item Width | 4.8 Inches | | Manufacturer | Tannus | | Manufacturer Part Number | TA Insert | | Material | Foam , Rubber | | Material Type | Foam,Rubber | | Model Number | TA Insert | | Mountain Bike Type | Mountain Bike, Road Bike | | Size | 26" x 4.0-4.8" | | Tire Type | Tubeless | | Tread Type | Multi-terrain or All-terrain | | Unit Count | 1.0 Count | | Whats In The Box1 - Whats In The Box3 | Instructions | ## Product Details - **Bike Type:** Mountain Bike, Road Bike - **Brand:** Tannus - **Item Width:** 4.8 Inches - **Material:** Foam,Rubber - **Tire Type:** Tubeless ## Images ![Tannus Armour Tire Insert 26 x 4.0-4.8, Fat Tire Tube, No Flat Bike Tire Liner, Puncture Proof Tube Protector for E-Bikes and MTB - Image 1](https://m.media-amazon.com/images/I/513JWzklj0L.jpg) ![Tannus Armour Tire Insert 26 x 4.0-4.8, Fat Tire Tube, No Flat Bike Tire Liner, Puncture Proof Tube Protector for E-Bikes and MTB - Image 2](https://m.media-amazon.com/images/I/91eQFVvz5wL.jpg) ![Tannus Armour Tire Insert 26 x 4.0-4.8, Fat Tire Tube, No Flat Bike Tire Liner, Puncture Proof Tube Protector for E-Bikes and MTB - Image 3](https://m.media-amazon.com/images/I/71H93jpH8OL.jpg) ![Tannus Armour Tire Insert 26 x 4.0-4.8, Fat Tire Tube, No Flat Bike Tire Liner, Puncture Proof Tube Protector for E-Bikes and MTB - Image 4](https://m.media-amazon.com/images/I/61XO1W+VClL.jpg) ![Tannus Armour Tire Insert 26 x 4.0-4.8, Fat Tire Tube, No Flat Bike Tire Liner, Puncture Proof Tube Protector for E-Bikes and MTB - Image 5](https://m.media-amazon.com/images/I/61zXD6KdIKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ puncture proof indeed! *by D***E on 19 November 2023* This product is fantastic ever since I put it on my bike.
