If you are serious about tubeless long term, just buy an air compressor. I seat every tire immediately with no fuss.

I'd say do a Silca floor pump and a small compressor. The airshot is well designed, but a portable compressor is more versatile.

If you plan on swapping tubeless tires while traveling, an airshot might be a good option since it's a whole lot easier to pack in your car. You can seat tires anywhere.

You can also use CO2 to seat a tire. I've read that it could be bad for sealant, but not sure that's true. You can buy a lot of CO2 cartridges for the price of an airshot.

Compressor hands down. I have an Airshot and many times it requires multiple re-fills before seating a tire which means lots of pumping. I wouldn't recommend it to anyone over a compressor. In fact, I can't think of many situations in which I would recommend one at all.

Forget what I just said, I have a like new Airshot I can sell you for $10 under retail! :)

3 gallon air compressor from harbor freight. Don't forget the standard 20% off coupon.

This is the same cost as the airshot: https://www.harborfreight.com/...ompressor-61615.html

Clearly, it is cheap. But is it good enough for seating tubeless?

Compressor for home; CO2 for travel (though that's going to be a rare case when you need to seat a tire on the road).

FWIW, In the past I've had CO2 make sealant all janky. I'd say this is a last-resort tactic.

You'd need to:

1. pop off tire
2. clean out sealant
3. put tire back on
4. use CO2 to reseat it
5. (maybe pump and deflate a couple times to flush out the CO2?)
6. add new sealant through the valve

This is very timely as I just picked up some tubeless tires and was actually looking at Harbor freights website yesterday, I would also like to know if that compressor would do the job?
