How to check tyre pressure, inflate & seat your tyres

Hello and welcome to this tutorial where we’re going to be looking at how to seat our tyres correctly, we’re going to be finding out how to check our tyre pressure. And we’re going to show you how to inflate your tyre using a track pump. So, let’s get right to it.


In this video, what you’re going to need is the following. We’re going to need a wheel whether it’s on the bike or not, and you are going need your track pump. Now, if you were doing a repair on the roadside, obviously the principles of inflating your tyre and seating your tyre is exactly the same. But ultimately, we’re just going to do this one demonstration.


So the first thing that we’re going to do is we’re going to show you how to find out what your tyre pressure is and where to find it on the actual sidewall of the tyre. So, you’ll be able to see in this clip all of the information that you need.


Now sometimes it is bonded within the tyre sidewall sometimes is printed onto a sticker, but it will have a minimum inflation and a maximum inflation, so you must make sure that you’re somewhere in between those two numbers. Where you go depends on the type of riding and weight of the rider. So a lighter rider could potentially be at the slightly lower end and give a little bit more rider comfort and a little bit more grip. If you’re on the slightly heavier end, then obviously I would increase the tyre pressure accordingly to ensure that you don’t then suffer pinch flights if you’re running tubed, or any unseating of the tyre if you’re running tubeless. So it’s very much a personal preference, but at least you now know where to find those tyre pressures, what your minimum value is and what your maximum value is.


So now that we’ve done that, the next thing that I want to do is show you and make you understand what seating your tyre is all about. So again, this next clip is going to run you through what seating your tyre is. Okay, so you’ll have heard the term seating your tyre before and if you haven’t then what seating your tyre is, is ensuring, and you can see here how we move from the grey section on to the black section, and there is a rib of rubber that we need to see that black all the way around the entire circumference of the wheel. If you don’t see that seating line all the way around, your tyre is not seated properly onto the rim.


What can happen then, this section here you can see is just grey, there’s no seating there whatsoever. And what will happen is, is that it’s actually this softer tyre carcass, that’s going to get the impact of the rim and will damage your tyre. So not only will it ruin the performance and the comfort of the of the tyre, and also don’t forget that whilst it’s not seated, the height of the tyre is different in this section than it is in this section and back here. So effectively the tyre is wobbling up and down as you’re riding. So that’s why it’s really important to properly seat the tyre.


So we’re going to do that just now. And I’m going do it real time. I’m going to inflate using this track pump here that we’ve got connected and you should be able to hear it snap up into position. So we’re going to inflate that tyre and seat it properly.




Okay, so inflate using  the track pump and it’s starting to push up. So just a few pushes, we can start to see that the black line, it’s started here before and it started back here. We can now see black appearing here. And just with a few more pushes, we can start to see it coming all the way around. It’s actually starting to chase itself around there, itself. So very nearly seated, we can see the bead line here now, we can see the bead line here now, so just a little bit more.


That’s it, do we hear that click – that click was just that final part here, seating backup on to the wheel rim. So now we have this black bead line chasing all the way around the entire circumference of the wheel. So that is now the tyre properly seated. What we now need to do is make sure that the tyre pressure is correct for going out on the ride. So that’s what we’re going to do next.


We’re now going to show you how to inflate your tyre using a track pump and how to operate the Presta valve system. Okay, so it’s now time to re inflate the tyre and what we need do now is attach the pump head, which is this part of your track pump on to the wheel valve. Now in this particular scenario we’re using a Presta valve because that is what most people will be potentially new to. The other type of valve that we’ve already discussed in another video is a Schrader car type valve which a lot more people will be familiar with. So that’s why we use a Presta valve.


So what we’re looking to do is firstly we need to remove the dust cap off the top of the valve. A Presta valve has then got this little section here that we need to unscrew and it will just get to the top of its thread. Now you can’t unscrew it all the way off it will come to its ultimate conclusion but don’t keep on doing it. It just literally needs to be unscrewed to the top Once you’ve done that give it a quick press. And what that does is it releases the high pressure internals and allows the pump to be able to pass through. If you don’t give it that first quick press, sometimes it can stay locked. So even with the valve head on, when you start pumping, it won’t allow any air to pass through. So just give it that quick press and then you released it, so that’s perfect.


Then what we need to do is we need to take our pump head. Now in this particular instance, this is an auto head so it will take a Schrader or a Presta valve without doing anything at all. But if you’ve got a type of pump that will take either a Presta or a Schrader style valve, but it’s on different parts, make sure you’re using the correct end.


What we then need to do is put the head vertically over the valve, push it down, and then lift the thumb lever up in order to lock the pump head on to the valve. We’ve now got a good seal, and we’re ready to inflate the tyre to the pressure that we need to.


So now that we’ve inflated the tyre, what we now need to do is we need to release the pump head off the valve. To do this, is a reverse, we put the lock lever to its low position. Now this is really important that we lift the pump head off vertically. If you bring it off sideways and on an angle, you can bend the top valve over and that can eventually snap and then and then you’re scuppered really so make sure you release the pump head vertically off the valve and you will then be sure you won’t damage this internal part.


Finally, screw down until it’s locked and sealed. Don’t over tighten it, but it’s nicely locked and sealed. We take our dust cap again, place over the top and done. We’re ready to go.


So hopefully you found this tutorial useful and we look forward to seeing you on the next one.
