An appropriate rim tape must completely and securely cover all spoke holes.
Hollow section rims require the use of special rim tapes such as SCHWALBE Super HP or SCHWALBE fabric rim tape. Rubber rim tapes are not suitable for hollow section rims, because the inflated tube pushes them into the holes.
The rim tape must cover the entire rim well. If the rim tape is narrower than the rim well it can slide and expose the spoke holes.
Alternatively, an adhesive, fabric rim tape can be used on all rims. Slipping cannot occur due to the heat resistant glue. The 19mm wide tape should definitely be used for racing bicycle rims (13C, 14C). The 15mm tape is recommended for the various hollow section and straight side cycle rims, which are often used on MTB and trekking bikes.
