Time to buy a good floor pump with rebuildable seals or replaceable hose. Figured I’d get on that seat tubeless tires as well, but reviews often say that part of it is unreliable. Any good pumps that do what I need?
Need a bike pump with airshot recommendation.

I've dealt with tubeless since the beginning and had all of the problems , and some that sealed with no issues. One thing that helped was to pre mount the tire with a tube ,let it sit over night. Remove the tube ,making sure to not unseat one side of bead . Reinstall the tire and add sealant , here a compressor is very helpful add a bit of soapy water and have the valve stem removed ,then put as much air in as fast as it will go . That works almost every time.

Plus this: TINY BIKE PUMP PRO-120 PSI High Pressure and LED Display Electric Bike Pump
So happy to never have to deal with a floor pump again; hate those gangly awkward bastards!

I don't run xc racing tires. And I never said that's how every tire goes on.
But I generally do run minions because they have the best combo of price, grip, and durability for me. And like I said, quality tires and they almost always seat well for me with just the floor pump. I've had similar experience getting DHRs, HR2s, Assguys etc to seat though I don't like them quite as much as DHFs.
My success rate getting all other brands tires to seat with a floor pump has been much less, probably less than 50%. Expecting a hassle is part of why don't often try other brands.
I seldom have a hassle with Minions.

This is a ridiculous take. Try that with xc racing tires! Or asymmetrical rims! Or any other goofy setup that is known to have issues that you don't use for exactly that reason. 🤣

Just out of curiosity I tried to seat a Maxxis Assegai DD casing on a DT Swiss XMC 1501 wheel that was not freshly taped and with a tire that had a questionable amount of sealant on the bead. I have a buddy who swears that he can do his with a Cycplus but he only rides XC tires and my guess is that he has only tried brand new ones so that wouldn’t be similar in effort.
I couldn’t get it to seat with any of the small ones and I tried a bunch of different pressure tricks to get the air to start flowing. I finally got it to seat with the larger Fumpa pictured but had to press the tire down enough to get air going. It was at 50% battery life when I started the test and ran out when I got it done and with 28psi in (was going to 40 just to test). I then popped it off again and tried my smaller compressor (Fortress Two Gallon from Harbor Freight) and it popped it on immediately. I have a much larger Stealth 12 Gallon that stays in my garage and is what I normally use which would have also made quick work of it but it isn’t particularly portable whereas the Fortress is what I use for air tool work around the house and it is easily portable. So, my point is I’d spend slightly more and get the Fortress 1 gallon for $159. It is impressively quiet and only weighs 26lbs. I don’t use the one I have all that often but it has been completely dependable to this point.

Something like this should attached to your DeWalt and allow you to inflate presta valves: Prestacycle Big Angle Presta Head
Another option is an air tank that you fill with your compressor at home, and take on the road with you. In theory you could also top it off at gas stations if you start to run low...

Removing the valve core is often the answer no matter what pumps the tire. I can need to do that in my shop with a significant air compressor as much as anywhere including with my tank/charge pump. For a long time now I do my first fill of a tubeless tire with the core out of stem.
I got the 2nd gen Trek pump seeing plastic bits with others and knowing they're usually good among many brands for warranty and small parts availability. It has been well worth it for trips such as can do a tubeless setup about anywhere and simplifying what I have at our cabin or travel from it to get things fixed.
Always removing core from stem also became a habit for how often I end up helping others. I'm a trail steward, have made or started pump tracks, am around lots of kids and families. That is often seeing folks who need help. It might not be perfect but that tank pump and removing the valve core seems like a few times per year saving the day for others move.

Let me get this straight, your Trek pump can pump the tires with the valve core removed?

I'm pretty sure he means he just overpressures the tire with the valve core removed, allows the tire to bead and once that has happened you just reinstall the valve core and your tire will remain beaded allowing it to be filled.

I think @Jayem is asking how the pump head attaches to the valve stem with no valve core in place. Normally the valve core is integral to the process...

To clarify, this applies to presta valves which as probably the most common mtb tire valve. The stem and valve core are separate parts. At no point am i removing the stem. Any new tire I buy that has a presta valve starts with the core removed, leaves the threaded end for the floor pump to attach to.
Yes the core is integral to the tire holding air but that's not what we're going for when doing this. Its just to set the bead and once you have that accomplished, pull the pump, let the air escape (the tire should remain beaded) replace the core and fill as normal.

Yes, the charged tank will for a brief moment work just like my air compressor or traveling to one does. Understand this is for seating the tire, not one no longer uses a valve stem.
With valve core out of the stem no matter what your high pressure source is you can use a Schrader valve adapter or a tapered Schrader compatible end to get much more air in the tire fast. The Trek pump includes a plastic one in the handle. Of course you can buy a better brass one.
That rapid inflation seats the tire on the rim's bead. Use soapy water. Then fill sealant and put your valve core in.
If a new tire I don't even bother trying to fill it with valve core in because this way is so sure and fast. It can still need some bothersome tires to be stretched with a tube first that that's rare if you do it this way. Also rare for common good MTB tires like tubeless road or gravel tires can be.
I thought most people knew to do this but maybe not for how many times I got tires mounted for people who were struggling.

The life lesson I continually re-learn in these forums is different people have different experiences than I have had. And even if their experiences seem implausible to me, they are real.
So, I would have said the bontrager pump was killer. The local shop actually uses the pump over the compressor for bike builds. Thing has been used hundreds of times. Works like new.
And no doubt others have had them fall apart on them.

Genuinely curious, what does it grip to when you attach the nozzle of the pump?
Unless you're using a compressor that you physically have to press to the valve (like a gas station air fill) I can't think of a floor pump system that doesn't latch to the threads of either style of valve.

The chuck of the bontranger pumps can easily grip on without the core attached. I have done it countless times.
Even with that, I still prefer the compressor.
As per OPs travel requirement, this is why I still have the blast pump. I bring it with me to races given bringing a compressor is unrealistic. So if that is the reason why you want a blast pump, I totally understand and would generally recommend the bontranger one.

I have no idea but I've tried to put it on there many times with the core removed and it never works ha ha.

I've been successful seating many tires with a regular floor pump without doing any real prep like trying to seat half of the bead before pumping like a madman, but there are certainly some that won't seat well. I'm at the point now that since I have a compressor, why would I ever want to ever try with a floor pump. I travel a lot with my bike and I picked up cordless compressor for travels. It's pretty handy and works great.
