Roberta, I think like all things, how long your tubeless tires will hold air depends on many factors. Some of it depends on the tires. The supple tires I like to ride from Rene Herse/Compass have side walls weaved from fabrics. Air leaks from the interface between the rim and the tire as well as the sidewalls, slowly. With sealants inside, the leaking air pushes the sealant toward the crevices, thereby sealing them. The first 1-3 days of setting up a tubeless tire involves a rinse-repeat cycle of pumping up the tire, spinning it to distribute the sealant, letting the crevices get sealed up, adding sealant and pumping up. After a handful or less of this cycle, the tire I have typically holds air very well.
I work about two hours from my house, and before the pandemic, I would travel to my office, stay for 3 nights, and come home for the weekend. I would need to pump my tires, once set up properly, maybe twice in 3 weeks. I ride 48mm RH/Compass tires are 30-35 psi and I am just north of 200 lbs. I top off sealant (through the valve with the core taken off) every 5-6 months. I heard from a local shop that Orange Seal's endurance variety can last longer. I bought a bottle and will give it a try. The difficulty in seating only happens at set up. Afterward even if the tire is completely flat you can pump it back up no problem. In case you need to replace your tire, or use an used tire on another tubeless set up, there are ways without going to the shop. Another person already mentioned that they have floor pumps nowadays that has a reservoir that unleashes a big volume of air at once. I don't have that, but I just go down to the neighborhood gas station with my Schrader to presto valve converter, throw in a quarter and use the compressor there. Just for reference. I had a tire that I set up once and never had to worry about seating the bead until it was time to replace the tire.
