Vee Tire 20" Fat Bike Tube - 20x4.0 Fits 3.50" to 5.00" wide

Universal Fit: Heavy-Duty 20" Fat Bike Inner Tube

Keep your adventure rolling with the Vee Tire Co. 20" Fat Bike Tube. Engineered to handle the high-volume requirements of modern electric and all-terrain fat bikes, this tube features a massive expansion range. While optimized for 20x4.0 tires, its high-elasticity butyl rubber safely accommodates widths from 3.50" up to 5.00", making it the most versatile emergency tube for your gear bag.

Technical Performance Features

• Wide-Range Compatibility: A single tube covers 20-inch tire widths from 3.50" to 5.00", reducing the need to carry multiple spares for different bike setups.
• Heavy-Duty Butyl Rubber: Constructed with consistent wall thickness to provide superior air retention and increased resistance to "pinch flats" during low-pressure off-road riding.
• Standard 40mm Schrader Valve: Features a durable 40mm AV (Schrader) valve, compatible with all standard floor pumps, CO2 inflators, and gas station air compressors.
• Cross-Platform Versatility: Also compatible with specialized 90/100-16 and 3.50/4.00-16 motorcycle-style tire and tube configurations.

Mechanic's Note: Fat bike tubes are large and can easily get "pinched" between the tire bead and the rim during installation. To prevent this, inflate the tube just enough to give it a round shape before tucking it into the tire. Always check that no part of the tube is visible under the tire bead before full inflation.
