Reliable in all weather conditions

Built for riders who use fat bikes in snow, sand, and soft terrain, this 26×4.0 fat bike tube is made from quality butyl rubber designed for consistent everyday use. It supports predictable performance during seasonal riding where wide tires are chosen for stability rather than speed.
Fat bike tires are typically inflated based on terrain and rider weight. This fat tire tube 26×4 supports commonly recommended inflation ranges of 5–20 PSI, providing sufficient air volume for wide tire setups when used with compatible fat bike tires.
Designed with a thick-walled construction, this 26 inch bike tube is intended for repeated use in wide tires, helping the tube retain its shape during installation and seasonal riding where durability is an important consideration. Each tube is solid 680 g weight and has reinforced valve base.
Compatible with standard 26 x 4.0 fat tire sizes and 100-559 specifications, this tube features a Schrader valve 48mm with a practical valve length for easy access on deep-section fat bike rims using common floor or hand pumps.
Suitable for fat bikes and electric bikes that rely on wide tires for mixed-terrain riding, this fat bike inner tube installs easily during routine maintenance, making tube replacement quicker while supporting stable riding across seasonal conditions.
