Mounting tubeless gravel tires on hookless rims: OK, I give up.

With a compressor, since you have a large volume of air at your disposal due to the compressor tank, if you use something similar to a Park Tool Shop Inflator or a cheaper equivalent, you have a gauge and a handle to squeeze to keep your air pressure in check. The Airshot is pretty small and only has a limited volume of air going in at one time, it will keep the volume of air in a safe zone. I read these hard to seat stories all the time and believe me, I have been there, done that. I tried 3 other similar devices to the Airshot and they did not work too well for me. Your results may vary. Ultimately, these ideas give just enough air, very quickly, to get the beads seated enough to let the air hold the beads in place. As Mikey said, try it, you will like it.
