This Deli Tire inner tube is sized for 26x4.00 fat bike tyres using the 100-559 ETRTO standard. It is intended for wide 26-inch rims where a high-volume tube is needed to support large-section fat bike tyres.
Use the ETRTO 100-559 marking as the reliable compatibility check, then confirm the tyre is within the 26x4.00 format. The Schrader valve works with standard car-type pumps and many workshop inflators.
