Tubeless tires will generally do this if you let them deflate all the way. Usually what I do is remove the valve core, air up the tire so the bead seats on the rim, pull the pump off the valve stem and immediately put my finger over the hole. Then, quickly insert the valve core and screw it in. This will let air out but if you do it quick enough, the tire will stay on the bead and you will be able to pump the tire up after the valve core is fully inserted.
The bike shops use high powered air compressors to do this so that they don’t have to take the valve core out. You can get an air compressor for your garage if you have one for pretty cheap. A small one will do the trick usually.
