In the February 9th edition of the
Escape Collective's Performance Process podcast, guest J.P. Ballard of Swiss Side (maker of aerodynamic bicycle wheels and other components) said that he has seen tires blow off hookless rims, even below the maximum allowed pressures, and that is why Swiss Side will never make hookless rim wheels. He also poo-poo-ed the idea that hookless rims provide any performance advantage to cyclists, the only advantage is that they cost about $20 less to make per wheel.
