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!
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:
pop off tireclean out sealantput tire back onuse CO2 to reseat it(maybe pump and deflate a couple times to flush out the CO2?)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?
