You'll know right away if 100% nitrogen will allow the sealant to do its job properly by sealing the bead and any potential air leaks. At the very least, you'll have a cheap and efficient pump for tire beading.

Sort of the plan-Schwalbe AirShott charge tank, the Zitto clone that's barely cheaper, and a floor pump with a charge tank are all much more expensive.

Also heard CO2 cartridges, besides being kind of expensive for bead setting, are also not great for sealant service life.

If it wasn't for the gas station near me, I'd probably try what you're doing. CO2 should only be used for road side repairs. They still recommend you pump them with air when you get home. My 25mm internal hookless wheels are the best at beading. With new tires and a bit of soapy water, they bead easily with a floor pump. My 21mm internal hooked wheels, require a quick gas station stop to use their free air.

There's also the possibility the sealant won't react properly sealing punctures since there's less oxygen in the tires. Though I'm no chemist, so for all I know everything I read was just BS and it'll work great!

Though if you can get free nitrogen at Costco and the container only cost like $35 USD, I'd get it as a cheap way to have pressurized gas for beading tires. I'm too cheap to get a compressor so I usually just bead my tires at the gas station pump.

Omg  "tubeless sealant might contaminate the pure nitrogen thats rich"... the air we breathe is 78% nitrogen.

as for "There's also the possibility the sealant won't react properly sealing punctures since there's less oxygen in the tires." That sounds more likely but there is the outside o2 that causes hardening. Sealant actually has lil fibers that form the structure of the patch. and then hardens.

One way to fix this is "set" your seatant with normal o2 and then after a ride of 2 switch to nitrogen... Because then its already ready. but then it does then leak out the tire... so who knows.. I would think if you set it it would be fine... but I wouldn't do it.... maybe if I was top athlete in the world trying for any edge... but day to day riding its silly.
