Tubeless tire liners also use standard inner tubes.Widths are 15, 18, 20, 23, 25, 27, 30, 35, 40, 50 wide * 50m long, with 10 specifications. Tire pad width selection basis: Tire pad width = inner width of the rim cross-section + 2~4mm, for reference only. If installing tubeless tires, start wrapping around the left side of the air nozzle hole and finish on the right side, covering the tire liner interface with the vacuum nozzle It is recommended to wrap the tire liner twice to ensure sufficient coverage Tubeless tires are wrapped with adhesive backing.In addition to being able to modify the vacuum wheelset through its good airtightness, the outer vacuum wheelset is modified by wrapping around tubeless tires, requiring a vacuum cross-sectional structure for the rim.Compared to traditional nylon tires, there are also differences.Not many advantages: improved issues such as displacement, folding, puncture of inner tube, and long-term breakage of nylon tire pads; at the same time, a traditional nylon tire pad weighs about 20 grams, while a tubeless tire pad weighs only 5 grams, which is not only safe but also very light. Package pad diameters for various wheel diameters: 26inch is 559 millimeters, which is 0.559x3.14= 1.76m , the tire padding of 26inch overlaps about 2m per wheel 27.5inch is 584 millimeters, which is 0.584x3.14= 1.83m , and the tire padding overlap for 27.5inch is approximately 2.1m per wheel 29inch and 700C are both 622mm, which is 0.622x3.14=1.95m. Each 29inch tire liner overlaps by about 2.3m millimeters The number of tire liners for various wheel diameters mentioned above is for reference only and is based on the actual measurements of the rider.
