TCS rim tape is adhered to a tubeless rim to provide an airtight seal between the rim and tire. Our 11-meter rolls provide enough tape for five wheels, while our 55-meter rolls will provide enough tape for 27 wheels – that’s a lot of wheels. All rolls are available in 24, 26, 28, 30, 34, 40, 45 and 50mm widths. What width of TCS rim tape do you need? WTB recommends using tape that is 5mm wider than the inner rim width, which is measured as the distance between the inside edges of the bead hooks of a rim.
