No need to use hook less ready tires. Our engineer started to study hookless design quite a long time ago. There is similar rim on the market, there is zero issues of holding tires for hook-less rims. The rim wall is more smooth and straight, the tire will touch rim walls fully and mounted perfectly. We have set up tubeless tire on it. It works well, absolutely zero air leaks. hook less 29er rim and tubeless tire the tire is mounted on rim start to inflate the tire use-soapy-water-to-check-whether-there-is-any-air-leakage prepare to mount the tubeless tire using yellow tape then adding sealant inflate the tire to 45psi using the same method to double check a while later Compare to head hook design, the hook less design is more durable. Because the rim wall structure is simpler. Then carbon fiber will be more continuous. It will be stronger than a hooker carbon rim at the same weight. Here is the testing data that we have done.

But we get the result the spoke holes can hold more than 300kgf tension.
