TCS rim tape is adhered to a tubeless rim to provide an airtight seal between the rim and tire.

TCS 11-meter rolls provide enough tape for five wheels, while their 55-meter rolls will provide enough tape for 27 wheels - that's a lot of wheels.

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.
