I use a AZUNO Bike Tire Inflator with Pressure Gauge. It claims to fit both Presta and Schrader valves. I didn't like the head so I replaced it with one from a pump with a failed gauge. I can tell you that the AZUNO gauge agreed with all 4 TPMS sensors on my car.
I have used it to seat everything from 25mm road tires to 4.8" Fat bike tires. If you have a compressor, it seems like a good tool to have. If you don't have a compressor, maybe consider getting one. My pancake compressor came from Homer a few years ago for around $100.

After my experience with tubeless conversion on my MTB I'd never consider it for the road.
Just run latex tubes with removable valve cores and squirt in some Stan's. The tubes only weigh like 50g.

Yesterday, on mile 24 of 107, I took a puncture on my front tire. Must have been a fairly big one, I coasted and watched it bubble for about 5 tire revolutions, then it stopped, I put it out of mind and carried on. I'd say that this is pretty typical of my experience, but it's not - I usually don't even notice the punctures.

Here’s a TL story: I changed out a tire about 6 weeks ago and seated it with an air compressor. I was doing five tires at the time and I let them sit for a couple hours before removing the valve and putting the seal in with a syringe, replacing the valve and airing up again.
One of the tires had a slow leak and I kept having to pump 20# or so daily to bring it up to proper pressure. Finally, I decided to remove the tire and re-tape the rim, figuring I had a poor tape job. I unseated one side and found that I had never put sealant in and had been riding it that way for 6 weeks. Of course, all is well now that I finished the job.

Update: was feeling brave today. Unscrewed presta valve slowly and let air out. Added sealant with a syringe…and of course the tire popped of the bead all by itself. Used the “air shot” 3 times and finally got the bead to seat….only to have it unseat before I could get the presta vlalve screwed back in the stem. Tried it one more time and pumped the air shot up to 145lbs and my Lezyne floor pump let go.😡. The pump now pushes air on the downstroke and the pressure shows on the gauge but on the upstroke the pressure immediately goes to zero. It’s like I’m pulling the pressure out of the pump on the upstroke(hard to explain), don’t know if it’s fixable or I’ve just ruined a $75 pump.
Next question. Tire is currently partially unseated from the bead. Will the sealant go bad overnight? Going to bring it to my shop in the morning and reseat the bead.

Also, if these tires are completely seated (witness line visible all the way around) and are unseating with low/no pressure, and if you're intent on keeping these tires (I wouldn't, but you do you), I'd recommend some MilKit valves - they'll allow you to keep some pressure in the tires (aim for 15-20psi) which should keep them seated while checking/adding/removing sealant.

It probably won't dry out, but why not just remove it and put it back in the bottle so that it doesn't make a mess in transport?

Although there is a good case to be made for buying new tires and using these as emergency backup tires.

Exactly this.. look at them as backups and as consumables that have a fixed lifespan anyway. It's not like you'd throw them in the trash can if you opted for other (better) tires.

GBK233 it’s too bad you did not take the early suggestion and inflate with the cores in place.
Lezyne sell replacement gauges which are relatively inexpensive and east to install, making the repair worth trying.

im returning the air shock(Amazon)….and getting myself a small compressor for future inflation needs.

Yup…def going to keep running these tires for a bit. They only have maybe 500 miles on them with no signs of wear. I got the sealant in and beads seated this morning. Will def upgrade tires at some point, but as long as these don’t get cut/damaged beyond repair….no sense in replacing perfectly good tires(aside from the annoying bead seating issue).

As far as tire recommendations, peruse this thread - https://www.bikeforums.net/road-cycl...ess-tires.html

Consider michelin power road tubeless. If those don't stay seated, your rims are crap too. I carry CO2 and a tube for a road repair. I won't mess with bacon strips or darts. I've let the air out of mine and found it takes some effort to unseat the bead, but it's doable on the road.

I always remove the cores.
- Mount the tire
- Slather bead with Schwalbe mounting fluid (soapy sponge works too)
- Use injector or just the small white bottle to put the Stans/fluid in the tire
- Use a blowgun or airshot pump to seat the tire
- Holding finger over valve stem, quickly replace core
- Air back up with floor pump
I don't remember ever having an issue with the tire unseating.

Mavic explained this in one of their videos online.
Def going to look for new tires. I also just found out that my presta valve is leaking….so I scrounged one from a spare tube I have.

You're likely experiencing the opposite - tire beads that are slightly larger relative to the rim. This would explain the unseating at low/no pressure and a slightly loose fit would allow more air to escape under the bead when trying to seat them, making it more difficult to seat them without a quick shot of a large volume of air.

No doubt! The range of sizes in wheels and tires is surprisingly large and surprisingly frustrating. I have another thread going on the topic - but focused on the damn near impossible task of mounting and removing (we should henceforth call this dismounting) tight tires. My wheels are apparently "big" and or have a very shallow center well. There is no way I'm pulling off a road-side tube swap with these. If a plug (they're tubeless now) doesn't do it... I'm Ubering home.

Exactly. This is the typical challenge seating mountain bike tires - they flop and slide... I've had to have another guy help - just to help keep the tire in contact with the rim. Super tight tires (like my problematic Cannondale Hollowgrams) are completely opposite - takes steel core tire levers to remove, a bead jack to reinstall... but seat and air up like they're tubed.

None of my MTB tires separate from the rim when I let the air out...I do this often to add sealant. I am currently using Knight Composites trail rims (29x2.35) and some DT fatter rims on the other bike (27.5x3.0) but they are relatively newer rims. I can snap the tire bead off the rim bead with enough thumb pressure. Road is still developing BUT I took the plunge yesterday and ordered some Zipp 303 tubeless rim brake 303 Firecrest wheels. Since my bike can only fit 25-28 (real measurement) I did not want the hookless anyway, plus it is a rim-brake bike. Time to go back to road tubeless. I just need to see if I should run the IRCs or Contis and order some up, though I have plenty of tubed GP4000s to get my by this season.

Just get a better tyre that wont puncture in the first place and you wont have to worry about the sealant plugging the hole or not. That's been My experience for the past two years or so. I believe you are venturing down a path of backwards logic. like - the more punctures you get, the better TL is, cos they (mostly) get plugged by the sealant.
