The traditional hooked rims mainly rely on the hooks on the rim to hold the tire, which has gradually become an inherent concept in the minds of riders. They believe that the combination between the tires and rims entirely depends on the hooks. Therefore, the hookless rims will make many riders feel that the tire will easily fall off without the hook and it is very dangerous.
But in fact, no matter whether the rim is hooked or hookless, its matching with the tire is not only limited to the hook, more is to rely on the rim bead lock and rim bead seat. A tight fit among the tire bead, rim bead lock and rim bead seat allows for good air tightness while maintaining a close cooperation between the outer tire and the rim.
In other words, the function of the hooks can be realized by the close coordination of the tire bead with the rim bead seat and the rim bead lock. So the hooks can be removed in exchange for better performance.
The key to achieving a close cooperation is that the size of the tire bead and the rim bead seat must be accurately coordinated so that they can have adequate air tightness. At the same time, the width of the tire bead should be matched with the groove of the rim bead lock, so that the tire bead can be confined in the rim bead lock to prevent the outer tire from being shifted inwards or even falling off.
All in all, there is no need to worry about the problem of the tire falling off if you use a tire that matches the rim.
