Liquid inside perfect for fat tire E bikes *by on Reviewed in the United States July 25, 2026* Yes, these are some of the top-of-the-line self ceiling tubes heavy duty for the price ### ⭐⭐⭐⭐⭐ No flats, great ride. *by on Reviewed in the United States May 8, 2026* Seem to be holding up pretty well. Have almost a thousand miles on the tire at this time. No flates, and seem to wean really well. Look great on the bike and installation was no harder than any other tire i have put on the bike. Living in Florida there are lots of sand spurs that cause a lot of trouble for off pavement riding. I ride almost everyday pavement and trails. If i have had a punchure, the self-sealing is working great. ## Frequently Bought Together - 2-PCS 26"x4.0" Heavy Duty Self Sealing E-Bike Tubes 26 X 4 AV32mm Fat Tubes Super Automatic Repair, Puncture Resistant Compatible with 26 x 4.0-4.5 Fat Electric Bicycle Tire Tubes Schrader Valve - Fat Bike Tire Liner, Bicycle Tube Flat Protector Compatible with 20"/24"/26"/27.5/29" - ULTRAVERSE 26x4 E-Bike Fat Tire - Robust, High-Performance 26inch Fat Tyre for MTB and Ebikes, Durable All-Terrain Directional Tread, Superior Density for Street & Trail Adventures-2 Unit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/238794297-2-pcs-26x4-self-sealing-fat-bike-tubes-26-x](https://www.desertcart.tn/products/238794297-2-pcs-26x4-self-sealing-fat-bike-tubes-26-x) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-12*
