Rim tapes are there to cover the spoke holes, otherwise the bicycle tube would push through the spoke holes and tear on a regular basis. All you have to do is making sure the tube is protected. The rim tape is either made of fabric or plastic (PVC). While fabric rim tapes can be glued onto the rim (polyamide rim tape) like an adhesive tape, the plastic rim tape sticks to the rim like rubber due to its own elastic tension, and the tube valve ensures it doesn't shift. Important: Be it road tires, MTB, DH or fatbike tires: The rim tapes you buy should match the rim size! Please pay attention to the packaging unit as some rim tapes are sold individually and others as a set of 2.
