Tyre-Rim Combinations
Hookless Checklist
- Check hookless compatibility of tyre and rim
- Check tyre packaging
- Check hookless compatibility table by rim manufacturer
- Never exceed maximum inflation pressure and maximum inner rim width!
- Pay close attention to proper tyre mounting and rim guidelines
Hooked vs Hookless rim
A hookless rim is characterised by its hookless sidewall. Unlike hooked rims, hookless rims do not have a form closure between the tyre bead and the rim flange. On hookless rims, the tyre is only held in place by the tyre bead and the frictional forces between the tyre and the rim flange. On hooked rims, the tyre is also held by the form closure of the tyre bead and the rim flange.
From our point of view, hookless setups seem to be more sensitive to deviations in system tolerances. Customers must follow all guidelines regarding hookless compatibility by tyre and rim manufacturer. Tyre and rim combinations, which are not specified on the tyre’s packaging, are not approved by Continental. To ensure secure tire and rim combinations, it is mandatory to check and follow the guidelines/standards of both the tyre and the rim very carefully, especially when using hookless rims. The maximum inflation pressure and permitted inner rim width are crucial for hookless applications.
The maximum inflation pressure for hookless and hooked applications as well as the maximum inner rim width can be found on the tyre packaging. Continental's mounting guidelines can be found here.
Hookless-compatible Continental bicycle tyres are fully functional without the usage of tyre inserts. However, tyre inserts are advertised to keep the tyre safely on the rim in case of a puncture. Therefore, this technology can be beneficial for tubeless applications on hookless rims.

Important notice on tyre-rim combinations...
To achieve optimum riding characteristics with the highest safety levels and to achieve optimum riding characteristics with the highest safety levels, the tyre and rim must fit and function as an integrated system. For clarification
on sizing, all Continental bicycle tyres are sized according to the ETRTO (European Tyre and Rim Technical Organisation) format.
The format tyre width in mm (size B) x tyre b as diameter in mm (size D), for example 23-622, is indicated on the tyre side in the tyre base area.
Alternative designations, such as 700 x 23C or 29 x 2.0, do not give a clear information about the necessary rim size.
1. Always observe the internationally harmonised ETRTO standard and combine tyres and tubes appropriately
2. Always observe the permissible maximum pressure on the side(sidewall) of the tyre.
Continental recommends that you mount bicycle tyres on hook edge type rims, unless stated otherwise (eg GP5000S TR tyres are also compatible with hookless rims). Hook edge type rims provide a more secure hold, especially with air pressures exceeding 44 PSI (3 bar). These advantages are safety-relevant. From 73 PSI (5 bar) onwards, the hook edge type rims are even stipulated by the ETRTO guideline. The only road bike tyres in the Continental portfolio that are compatible with hookless rims are GP5000S TR, GP5000 AS TR & GP5000 TT TR. They must not be inflated over 73psi (see chart below).
This rim type, for example 622 x 19C, is indicated with a rim base diameter in mm (sizeD), the rim width in mm (size A) and a “C” for crotchet (Illustration 6 ).If the size information on older rims is no longer legible, the rim width can simply be measured by using a calliper from one hook edge to the other. An overview listing the appropriate rim width for every tyre size is also available from ETRTO (also look at the chart below).
Non-matching tyre-rim combinations can result in a sudden tube failure or make the non-matching tyre-rim combinations can result in a sudden tube failure or make the tyre jump off the rim. Risk of accident with unforeseeable consequences.
