I Find it best to first fit with an innertube after applying the rim tape. Pump to 60psi and leave overnight. That makes sure the tape is stuck firm everywhere and gets rid of any wrinkles around the spoke holes etc. Nothing worse than getting to the end and find sealent leaking through the spoke holes.
I have a gravel bike that is max 50 psi, but would you still recommend the 160 psi to bead it and deflate after? Is that pressure okay on the tyre? With the tyre already part off as I was going to change the sealant as changing brands, is it better then to still inject it through the valve? Is this to stop it spraying out if trying to bead it with it in? Good video, thanks.
so your tires are unseated right ? so it wouldn't be air tight , so the idea is that when you use the 160psi to inflate the unseated tyre , the incoming air would be fast and furious enough to compensate the outgoing air escaping from the gaps and the tire would seat, so that means not all the 160psi would be in the tire
It's 160psi is in the inflation chamber. As you dump the air into the tire, the total volume increases dramatically probably 2-3x with a big 29er tire like that. You'll also lose a bunch of air before the tire actually seats. By the ideal gas law, the pressure in this higher volume system will drop proportionally. The trouble is not blowing the tire off the rim, it's getting enough air fast enough to get it to seat rather than just escaping between the tire and rim.
If you load the canister with 160psi, does it hold the pressure for a while, or does it leak slowly till it empties after a couple hours? I'm asking cause I just bought one and it leaks slowly and I want to make sure that's normal.
@@phantombigballs8165 I wouldn't want to do that. And in fact the instructions say specifically not to do that. I just like to put all my stuff through tests.
Yes, you can use it as a regular pump. Turn the ring in the inflate modus, than it has the function as a normal pump. The "booster" will be only filled with air when you are in charge mode.
Will that pump “inflate / seat” a 26x4” fat tie bike tire ( tubeless ) in one blast when you put the pump in Inflate mode after you pumped up the tank to 160 psi ?
Can unloading 160psi at once damage the tire? I ask why the tires usually have a recommendation of 55-60psi. Or maybe those 160psi are not all absorbed into the tire? Please answer, I am looking to buy this Joeblow and I have this doubt.
@@cassioa.borsatto5128 Hey! First, to add on to mushies answer even if you inflate the tire above its recommended PSI, the worst thing that can happen is the tire popping off the rim. It will be very loud but won't damage the tire or rim.
Just bought one of these and it's pretty useless. Doesn't release the pressure quickly enough and certainly didn't seal the bead. Looks like I just wasted $160 plus the cost of tubes I now need to use lol.
I had the same issue - I think you need to keep pressure on the pump handle as you rotate the dial to release the air from the chamber. I've got to give it a go myself to be sure but that appears to be the only difference from when I had the same issue as you!
This is the best instruction on installing tubeless tire. Even better than GMBN.

Good suggestion
Thanks for doing simple step-by-step. It really helps!
I ordered a Topeak JoeBlow Booster online and I will try it with this simple instruction. Thank you, TopeakCycling☺🙏
Don't forget to check for leaks around the valve stem where it exits the rim.

My question is if you pre load for 160psi but the tire max psi is 70 then how does that work?

Do you recommend less pressure for road tyres such as 25/28’s? 160 psi seems high?
Seems really high, to me.
I saw another video where it’s recommended 120 for proper road tyres. Looking for any experience out there

Is that Matt Riddle? 😂

It will leak slowly due to the Hugh pressure.. not really sure why you would want to keep it pressurised though??
@@phantombigballs8165 I wouldn't want to do that. And in fact the instructions say specifically not to do that. I just like to put all my stuff through tests.
Can it be used as a regular pump without engaging the "booster"? I mean, for any pumping that's not for seating a tubeless tire.

@@Spider-ut4we thanks my friend!

How do I use this pump without the valve core in the valve?
How are you supposed to use it without the core in it? As soon as you remove the pump all the air will shoot out...
What about tweezers?
Where can I find "tubleless tape"?
At 1:27 lol

You can see when he releases the pressure into the tire, the pressure falls below 40psi. The volume of the pump is less than the volume of the tire.
@@mushieslushie Thanks for the answer, I believe that a lot of air must escape until the tire settles on the rim.

P1V1=P2V2... (ideally, but close enough).

My issue is how the nozzle fits onto the (presta) valve, can't seem to get it to connect (clamp) securely like I'd assume it would.
How about getting an air compressor 😂
Hopefully you're not riding on 160psi.
he can get itt
I've been doing this wrong all along.
WHAT AREDICULOUS WAY TO FILL A TIRE LIQUID THAT SLOSHES WILL TUBLE AND AFFECTS THE RIDE LIKE A MASHMELLOW STUCK TO THE OUTSIDE OF THE TIRE
