Why do my tubeless tires go flat?

There are three main reasons for initial tubeless “failure”: the tape rim is fitted incorrectly or has been damaged. the tyre isn't seated properly.6 июл. 2020 г.





If you watch a lot of GMBN articles, how many times have we probably told you that tubeless is better? It's easier and you won't get that many flat tires, well in this article we're going out there and we're going to prove that. We'll see if it's easier and you get fewer punctures with some testing. So let's get started right away.

So, if you don't know what tubeless is, it's basically that you are giving up on tubing. You need some tape, you need your valve, some sealant, bundle that together with your wheel and tire and hey presto! You're tubeless and ready to go. If you want to know how to do it then we have a full, in-depth article that shows you how to do it.

But let's come to the first example. At first, tubeless is lighter. Let's just prove that to the scales that I have set up here on my super-light carbon FSA rim.



Then we will put the tire on. Okay, so that weighs 1,615. And finally we come to the inner tub e on.

So for this setup it comes in at 1,855. Now let's take this tube off again. We are going to put the valve in the rim itself.

If I can find the valve hole, I'll just put it in the tire. So now let's add 100 mils of tubeless sealant. That brings me to this line here.



Okay so that was the last piece of my sealant. I have 100 mils in it, that's the right amount per bottle, and it weighs 1.74 kilograms.

That’s a whole 100 grams lighter. Mythbust One finished because tubeless is lighter. Okay, so we've proven that the tubeless setup saves 100 grams per spar wheel.

But what does that actually mean on the bike? Because you're going to save some rotational mass. Well, rotational mass is the mass that is actually always moving, so things are how your wheels have the greatest effect there. Well, that is, like the frame itself or even the shock on the bike.



But how does that affect you when you drive? Let it be said that a rotational mass can do up to three times as much as this stationary mass. So we have just saved 100 grams, so three times as much. We have saved 300 grams and then we have two wheels.

We saved 600 grams for a fairly simple and easy upgrade that won't cost you too much. Now all of this is done with the formula for the moment of inertia. If we have any scientists out there, we'd love you to prove that we're right, or even if we're wrong.

You can let us know in the comments section below and I will mark your work. So we learned that tubeless is lighter, you have less rotation and weight, but what do we? I really want to know if you're going to have fewer punctures? So let's test it out. Because I have the wheel in the jig.

I'll take my tool here, it's a thorn. We're going to poke the tire and put a hole in it and see if it seals. So are you ready for this? Three, two, one and I'll get my tools to tire. (Hissing sound) Okay, you can hear air coming out.

Let's twist it and hopefully seal it up. Okay, we have the sealant come out. No air escapes.

So that proves the sealant, tubeless setup did its job. Now if you had a tube in this wheel it would be a game if you pierced the init as you wouldn't be able to seal the tube. The air would escape and your ride would be over. that's another tick for tubeless.

Okay, so go on, we're getting an item in the tire. Let's talk more about an impact and something like a snakebite. Now watch out, what happens when you get a snakebite is you have your impact, I'll take my hand as an example and it goes right in.

It goes through the tire and hits the tube on the rim. Now this impact, because it combines against two things and the tube is in the middle of it, the tube is actually pinched and that causes the snakebite. Those two tiny little holes, almost like snake teeth, ha I went into that tube myself and that causes a flat tire.

Now with tubeless, because you don't have a tube in, you won't get those snakebites. That's another reason you want to ride tubeless, and of course, fewer mishaps mean more riding time. Since you have better puncture protection with the tubeless system, this in turn means that you actually get more grip.

And by that I mean that you can actually get depressurized because if you think about it, you'll have more pressure when you operate a tube system. Because you don't want to get through really hard and get a snakebite, or you don't want anything to get into the tire, I need to apply a little more pressure, but because you get rid of those two problems with the tubeless system, you can release a little pressure. Now I am not talking about a large amount here.

I'm talking about two, three, four PSI. It all comes down to a little experimentation because you don't want the tire to roll or burp under you. So take this tire with a pinch of salt.

Experiment a little. Take out some PSI. You will have more grip, which means you will be able to ride those turns harder and you will be able to take a few breaks later.

Which in turn means that you will get faster and have more fun. Okay, so for our fifth and final test, I have two? Wheels here. The rims are identical, the tires are identical and the pressure inside is identical.

The only difference is that this one has a tube and this, well, it's tubeless I'm doing a little pressure test to show you when they actually deform under pressure. So when I squeeze this one with the tube, you can actually feel that it's pretty hard to deform the tire. When I take my tubeless tire, it's actually a bit easier to deform that tire.

Just because you don't have inner tubes it means less resistance is needed to actually deform the tire. This means that you compensate for the bumps a little more. It will absorb some of those minor impacts.

Maybe if you drive over roots and rocksat at a slower pace, it'll just give you a smoother ride. This is not that noticeable to the vast majority of drivers. But when you ride at the highest level, every little benefit really helps.

Going on a few facts about why you want to go tubeless. Hopefully I destroyed a whole bunch of stuff and told you why you'd want to do tubeless. It's so simple, and it's such a good upgrade, that you'll probably never, ever want to drive that tube again.

Do tubeless tires go flat?

It's pretty rare to get a flat tire when you have a tubeless setup. The sealant inside your tires will quickly seal small holes and cuts to keep you rolling on the road or trail. However, flats are always possible – even with tubeless.

How long does tubeless sealant last?

The sealant should last an average of 2-6 months depending on factors such as: temperatures and humidity in your area, how often you ride, where you store your bike (cooler is better), tire casing thickness, number of punctures the sealant has already sealed that you never knew you had, etc.

Hey Henry, I have used this FSA gradient bike from a careful owner and it is lightly used it is in perfect top condition and full to the brim with sealant Heyguy just for you gracious thanks man anice guy kind of strange how they are actually a different bike model, but I think is that easy? the magic of cinema how long does tire sealant last and how to remove it when it has dried and stuck to the rim how to free tubeless valves well when it comes to tubing systems the questions similar to how the sealant comes thick and fast we have many articles about it, how to setupjubileus, but this is a article on how to brush up your sets from bless to blesssystem without the tube setup. Blake, the mechanic's headache, Samson has learned a lesson, never again, he's just got on with bikes like few others he loosely rides, not so much that he stole more of a suitcase that he wasn't interested in at all their resale value, basically what happened was that his Blake was perforated and the tape was torn pretty badly so he got bums atube in there, but what is essentially all of the leftover sealant is now Jess and getting into the rim that's not that big of a problem, but Oldgubbins here inherited it the night before a shoot and I put a new tire on to set it up as soon as I could, but for the next one or how long it was, the sealant was dripping only half an MVorifice out and it's kind of sad my garage I didn't get around to cleaning it but today is the day I'll be cleaning this up so it's absolutely factory free ish, so first up let's pull that tire off not nice you can hear it's completely jammed not letting any pressure in or out in this case okay so what you can do and that's pretty cool what i wanted about it to the camera, this one is used here, the cap also acts as a tool to remove the valve and whatever you can get out like that I'll put aside and deal with it later on seal remover we read the instructions carefully hmm and we spray it up, okay so I really want you to really go down here in town okay but not literally we lock up your sausage, once you do that you will gently let it go to do it for about five ten minutes, if you happen to happen to make a youtube article of it, you can bring back the visual metaphor of a cup of tea to show that this is the reality and time has really passed from gonna clean it up properly and now also use the glue remover on the inside of your tire how long should the sealant last until it dries well that really depends on how often you use the wheel if you use it a few times a week that in my experience lasts the sealant lasts as long as the tire, but if you leave it in the tire and store it, it will likely dry out over about four months. Now make sure the wheel is dry and squeaky clean and we're going to add the tape, now you know the score here we we're going to use the correct width, nice and tight and we're going to overlap at the valve hole Okay, now it's time to put your valves in to freshen up tubeless valves well, you can put them in warm soapy water and if they are really that filthy valvecore it is indeed a little help, but to be honest you can get the best results in my experience which you can get on ebay for about seven billion of which for 365 and I would recommend that if you need to polish the valve yourself.

Sold these seals separately which is nice? ofcool so it means that the two metal pieces should last the life of the wheel now the tire and rim were cleaner than a used world of the twenties we are going to reassemble them and inflate the tire on the seat again but we will Don't Add Sealant Yet Now that your tire is all around on both sides, we're going to undo all of your hard work by putting all the air back up straight and removing the valve barrel. Now it's time to put the sealant in, if you I inject it through the valve like I do we want the sealant wrapper at 12 o'clock then put the sealant in the rim at 6 o'clock use the guides on the package to measure it, then let's remove it at 3am for you digital watch lover So clever now no handy metaphor for you and then we shake the wheel again to get all of the sealant where it needs to be and then we tease the neighbors downstairs by hopping the wheel around and there we have it folks there is a wheel successful Some tips that I have no doubt overlooked, how do you keep your tubular sealant in your tires and nowhere else like you clean it? Ribe and we'll see you next time thanks guys
