YunSCM 20x3.0/3.5 Bicycle Tubes, Thick Wall, with 48mm Schrader Valves, Ideal for High Rims, Suitable for Fat Bikes and Mountain Bikes

[20"x3.0-3.5 Bicycle Tube, Thick Wall]: Compatible with 20x3.0/3.5 bicycles, with 48mm Schrader valves and high rims, this tube is ideal for mountain bikes and fat bikes. The tube's air intake is the same as that of motorcycles and cars, making it easy to inflate. You can now use the same tire pressure gauge you use in your car, making tire pressure management much easier. Note: Please check your tire size before purchasing. Tire size is usually displayed on the side of the outer tire. [Space-saving and easy to carry]: The 20-3.0 tube folds up into a small space, making it easy to carry when riding long distances, avoiding the embarrassment of not being able to ride after a flat tube. [New Release] [Thickness Design]: To meet the needs of frequent cyclists and further enhance the durability of our tubes, we developed a thicker, reinforced tube that is approximately 25% thicker than standard tubes, with a thickness that is visible to the naked eye. This improves the tube's explosion resistance and puncture resistance. [High-Quality Butyl Rubber]: This material's 20 3.0 tubes provide better airtightness and can retain air for a longer period of time, eliminating the need to constantly inflate them. [Budget-Saving]: Doing it yourself saves money compared to going to a local shop to replace your tire. As a spare bicycle tube, it can prevent the embarrassment of being unable to ride after a tube bursts.
