Getting a puncture is part of cycling. In this video we show you how to fix a road bike tyre. If you're on a mountain bike the technique is exactly the same!
The simplest way to fix a flat tyre is to replace your inner tube. This is the technique that Daniel uses in the video. If you're after more mechanical How Tos, we've got you covered - take a look at our playlist: gcn.eu/maintmon

They seem to have waited for one of them to actually get a flat before putting out this tutorial, authentic ;)

Watching this on the road rn. This is my first puncture that I am fixing myself during the ride
I have had many flats over the years. The one pro tip I can give is: after you take out the "flat" inner tube, be mindful of which way the tube was installed and then try to inflate it so it has some decent pressure. You might determine where the puncture was just by the hiss of escaping air. I normally turn the tube around with it close to my lips to feel where the air is coming out. Make sure you go all the way around the tube, and don't just assume you only have one puncture! I can't stress this enough.
Once you know where the punctures are, you can compare the location in the tube to the tire by where the valve stem is. Investigate those areas on the tire completely and remove any debris, nails, glass, staples, wire, etc that caused the flat. Carefully feel around the inside of the tire and look for any other foreign material in there and remove it and don't forget to inspect the outside of the tire too. Then patch the tube if it's only a small puncture or replace the tube completely if it has more than 2 patches or punctures.
The reason why I like to check the tube for punctures is I hate cutting my finger open on sharp glass, or poke myself with wire or nails. Also, you may miss a second puncture location when feeling around the tire if the debris only lightly penetrated. As soon as you reinflate and ride off, the pressure of your weight could cause the debris to poke through again causing another flat. And I always recommend patching a tube first. Patch kits are fast, cheap, and reliable enough these days. Keep your spare tube only as a last resort, or where patching is impractical.
I hope this was useful, and drive safe everyone!
GrognardOfXCOM Another good way to find holes at home is to run the tube under water in a basin and look for bubbles.
IronFreee This video was intended for roadside flats, not at home. However, if you have a large enough water source nearby (such as a creek, river or lake) submerging the tube is definitely an option. I've used a drainage ditch for this already and it does help to find the leak fast. Patching a wet tube isn't practical when it's cold or wet out unless you can thoroughly dry the tube off. ;)
GrognardOfXCOM that’s a very long comment .
Rosa Velázquez that's dedication and passion for whatever you do. Hats off mate for sharing your experiences.
GrognardOfXCOM But if it was a pinch puncture I don't need to do these steps right?
Just had my first flat the other day near the end of a 48 mile ride. Glad I watched this video first. I did everything the way they recommended and was back on my bike in no time flat (pun intended)
love the pun!
I got one last week at mile 20, walked 15 miles home with the bike.
It's really important to make sure that the tube is seated inside the tyre properly as described in the video. I got to about 80 psi and the tube exploded in my face.
4:11 "How to pump like a Pro"
I still couldn't fix my own flat after watching this video. Maybe I am just weak sauce.
Not likely (or fun) with a small hand pump, but when using a floor pump, it helps if you pump the new tube (inside the tire/tyre) up halfway and then deflate it before pumping to full pressure. This allows the tube to even itself out lengthwise and will pull itself out from under the bead if it caught.
Love how he just removes the wheel without really explaining what’s going on 🙃
My back tire held up for 10 years I finally got a flat last Saturday. I was going to take it to the shop to get it changed but watching this video I see it is not hard to change the tire, I already got the tube out need to buy a new one.
What brand of tire did you use
A basic flat tire lesson that is fundamentally correct. Conveniently correct? No. There is one more thing you should have with your tire tools, tube and pump. A pair of 'surgical' style disposable rubber gloves. Few of us mortals have wheels, derailleurs and chains that are clean. The gloves take up virtually no space and will let you continue your ride without greasy grime coating your palms, thumbs, fingers, handlebar tape, and cycling shorts.
When replacing the tyre leave the bead at the valve stem till last as this will avoid the tube being pinched push valve stem in but not all the way through so that you can reseat the bead without pinching tube at stem fixing.
This video should have been titled “how to change a flat tire”. He didn’t fix a flat tire.
Now I'm gonna remove the tube inside my bike again, since it's going up and down, the tube was not properly placed, I thought my rims and spokes was misaligned somehow, but it's not. Thank you GCN!
What pump are you using to pump the tire up, can you mention it.
Best video on youtube! You make me realise how quick and simple it can be when you're half way from work with a puncture praying to God for help. Thanks a lot!
Thanks!. Now off the fix the daughters rear tire.
A good tip is to look at the old tube to see where it has been punctured, and then you can get a good idea where to look on the tyre in case of glass etc.
Got my first flat today (back wheel, argh), I memorised this and the other GCN puncture vids. Went through every step and completed the task, however my new inner tube got a puncture almost instantly... I forgot the first rule you taught - check for a thorn in the tyre. Post-mortem revealed it was indeed a rather large thorn.
As I stated above, most frequently the tire needs repair; you must fix the hole in the tire to prevent the tire from simply pushing back through the hole, thereby rupturing itself, when properly inflated. Tire change videos that don't stress this step are simply balderdash.
Thanks. I came off my bike for the first time a couple of weeks ago and enjoyed my first flat around Lake Burley Griffin today. I should've been more prepared as I had to walk > 5k's back to get home. Will be better prepared once I fix the flat! :-)
GCN videos, always interesting, informative, and usually funny! Thank you guys. I always look forward to your next video.
Thanks Steven Craig!
Thanks very much, i have just got into cycling here in the Philippines and I was clueless about all this. Thanks to your videos I now carry spare tubes, patch kits and repair tools. I'm still worried about messing something up on the complex mechanical on the back wheel if I have to pop it off! great work!!
i would say another important step before pumping it all the way is to push the nozzle into the tire so that the tube doesnt protrude when fully inflated. i learned this the hard way...
Had my bike for 3 days and already have a flat tyre...😕
Bruh same
I swear you are supposed to replace the tire or you will just get a puncture again from friction on the road to the tube
Nice and clear video! One addition though: I once learned a trick in my bike repair shop.
Most, if not all, tires can be put back on the rim w/o the use of levers. If you pinch the tire at the opposite side of the part that still has to be put back on the rim, so it sits in the deepest part of the rim, you should be able to get the remainder on the rim w/o using force and with your bare hands.
that's a great tip!
The part about feeling the inside of the tyre just saved me from another future flat tyre!
Great video. Showing detailed step by step instructions with easy-to-understand explanation.
Mark your tire on the side right above the valve stem before you take your commute. That will give you the orientation between where the air is leaking out of the tube and the corresponding place on the tire.
WICKED vid!! really great details that made things a lot easier with this kind of tire (road bike) vs the regular bikes (that we all know). THANK YOU MAN!
3:20 You should NEVER use a tyre lever to get the tyre back on the rim. It is all to easy to simply pinch puncture the new inner tube with the lever. I worked in a bike shop with Cytech qualified mechanics and they were adamant about this.
The real solution:
If you are struggling to get the last section of tyre back on the rim, go to the opposite side of the wheel and make sure that the bead is seated as deep into the rim as it will go. The extra 1mm provided will give you the freedom to push the remainder of the tyre on to the rim with your thumbs.
In theory this makes sense. I will try next time instead of destroying 2 new inner tubes with tyre levers. :0)
I like this, will deffo watch a few times in future to make sure I would know when out and about...
Easier demonstrated than done by a novice biker
I KEEP destroying my inner tunes because my tire is SO tight, wth can i do? Impossible to do with just hands
Matt somethingorother - buy the tool from koolstop that rests on the rim at the back and stretches the bead up and over at the other front rim. Does not touch the inner tube. If no tool, rest wheel on floor with last part at bottom, and starting at top, work the excess "length" of tyre around and down on both sides, pushing hard with your hands. Once the excess is at the bottom, but held tight in place, lift wheel up, and it will go on much more easily, possibly without tyre levers. If still does work, find a combination of wheel / tyre - some tyres are looser than others, some wheels slightly more difficult
He showed you how to look inside the tyre to make sure that the inner tube is not pinched by the bead - this is important, and check all the way round carefully on both sides
Matt somethingorother - just remembered my tightest ever set of tyres, everything failed, I found the old school answer on the internet - warmed / softened them in a low oven before fitting. It did work, but I expect they will not come off at the roadside so not a perfect solution. Mine are just use for racing
Thank you for posting this. I just fixed a flat with this helpful video
thanks ! You make it look easy. I hope I can do it.
my tires held up for 3 years, and had my first flat today.. and thanks to your videos i was able to change it quickly and get back on the road.
3 years wow, what tyres did u have, I got 5 months out of time but there anti punchure ones so it should of lasted way longer
I've been changing innertubes for years and there forever exploding on me, thanks for the help!
Thanks for this video! I had a puncture on the way home last night which I fixed in 5 minutes, but then spent the best part of an hour trying to balance the tyre to no avail. Watched this video when I got home then fixed it properly in 5 mins :)
if the hole on the outer tyre is quite big, should I repair the outer tyre as well?
Yes, absolutely! This is a subject not covered by the video, and in most cases you will need to repair the outer tyre. Otherwise, the inflated tire pressure will simply hirniate the inner tube once it's highly inflated.
I was three minutes off campus when I found that thorn you spoke of and was so glad I'd seen this video. Thanks.
Awesome instructions. Pretty straight forward.
Like a boss ! I got my first road bike puncture after 2000 km of riding, gonna try to fix it.
That is a slow, and silly way to do it. Pump flat tire up, find deflating hole, remove just that section of tube, patch, return into tire, and rim, reinflate, ride it like you stole it ! Much faster manner of doing t hings !
Mine s deflating so slowly you cant find the hole
Your bike is a beauty!
I must say thanks to this gcn maintenance video i was able to kom my flat repair! i had alot of practice today with two flats within 5 miles!
Cheers lads, simple tutorial but useful for a beginner like myself!
Thanks Alex Firth
Can you tell me where this video was made? You sound British...signed curious in Canada...Alberta...Calgary
***** In Britain!
Thanks so much for this! Very clear and helpful!
Thanks for all of y'all videos, I never knew about the canter lever on the breaks.
How to fix a flat tyre is fine but how about doing a video when you are on a country road it's pitch black and pissing down with rain I would like to see a video on that as this is normally when these punctures happen.
This happened to me recently and lucky I have a rechargeable mini headlamp in my bike maintenance kit so I was able to do the work on a pitch black road hands free.
top video! but why arent the valves lined up with the tyre logo? #velominati
Ride Biblical spent a while looking for this
Great content. If only I had a quick release mechanism!🤣
Finding trash in your tire can be made simpler with a piece of lady's hosiery because, as we all know, hosiery catches on everything. I also carry a needle nose plier when the trash is too small to be pulled out with fingers.
Just before completing the mount of the second bead, pinch the mounted part of the tire so the beads are at the bottom of the rim well. This provides two advantages: 1) The last part of the bead is easier to mount, and; 2) Because the beads have forced the air in the tube to be concentrated in the part of the tube where the tire isn't completely mounted yet, the tube will be forced into the upper reaches of the tire thereby almost completely eliminating the possibility of pinching the tube.
That's not a cantilever brake.
Before inflating the inner tube, should I put something inside the tire to cover the hole and protect the inner tube? Folded dollar bill? Piece of duct tape? Thanks!
There is no actual 'puncture repair' here involving the glue, patch etc. Is that because it was such a small puncture ie a thorn and a simple inner tube would fix it?
The best way to get your inner tube to not snag, is to pump a bit of air into it to make it round out before fully seating the bead. If it's completely flat then it will pinch for sure!
I got it all fixed up then over pressurized the tube when airing it back up and busted a hole in it 🤦🏻♂️
Sorry but I would never lay my bike on the ground... I'd rather plant a tree and wait until it is tall enough to lean my bike against it.
If I’m near home I just carry my bike and run home in bare feet and cycling shoes in two of the three back jerseys pockets
for years i have been putting it into a bucket of water to find the puncture. Sometimes multiple punctures have occurred
What is this and why TH-cam recommend it to me
This is not "fixing" the tire, but rather replacing it.....
My thought exactly. Disappointed tbh.
I have an idea for video! I belong to the kind of people that almost exclusively ride tubulars. I have many reasons: comfort, security, weight, performance, its cool, I like the smell of glue, some tubular wheels are cheaper, etc.. So, why don't do a vid on puncture repair for the tub-folks? (I don't find them to be particularly cumbersome but nonetheless, I might have missed some tips and tricks.)
I noticed that like every other video on TH-cam edited the part where you actually put the when back on. You cut the video three times to make it seem easy........... Be real
Seriously, how many people carry a brand new tube? All I carry is a repair kit that puts a patch on the tire.
this is more REPLACE a Tyre instead of FIX it. it's always much more costly to buy a new tube than putting a tip on where you neeed, yes , it's only for temporary using, but it works well. can you guys actually upload a video of "how to patch holes on tube?" plz
Hi ***** - this Roadside Maintenance video covers patching a tyre: How To Repair A Puncture On The Roadside - GCN's Roadside Maintenance Series. Hope that helps!
Does anyone still repair punctures? I just chuck the old tube in the ditch and put in a nice new tube
Why wear a Halloween costume (I'm a bicyclist) for this?
The title is misleading. The video should have been titled ' How to replace a bicycle tire's inner tube' or so, because that's what it does. This does NOT show how one can actually fix a puncture using a puncture kit - this involves patching the punctured tube and there is no need for a new tube.
This video answered my question, therefore I gave it a like 👍🏼
What about partially inflating the inner tube once it's out to find the puncture instead of searching for it by hand, that seems like the better option... Also if you get a long gash you can use in my case a folded up dollar bill to keep the inner tube from popping out of the tire while you make your way home.
He replaces the innertube he is checking the outer tube for the offending object.
Thanks Great video, you’ve helped me change my bike tire 😅
Had Mr Lloyd left some article on the ground at 5.13
If you've a tight (big) rim then use Continentals as they're slightly bigger in diameter than vittorias and it can be easier to remove.
Bontrager levers are good as they're wider than the type used ?
Showing in this video very obviously; The bold and cap on the valve are not installed. In case you have a blowout, your inner tube will be able to detach from the rim, preventing a nasty crash (if avoidable at all).
You don't have to worry if you have slime in your tyres it can seal punctures to a size of three mm problem solved I had it in my mountain bike and it worked wonders planning on putting it in road bike when I get it too
hi GCN im a fan of yours,i have a problem that what should i do if my handlebar is loosen and i dont have my tool with me in the middle of nowhere.Pls help me,its been troubling me for a long time.
Hi, we are in the process of creating a flat tire bike repair kit. We would like to add a link to your video as part of the instruction. Would u mind?
Hi Had my first flat today caused by a pot-hole, I got the tube replaced and back in and then made it back home. Looking at the tyre when I got home the tyre does not seem to be sitting central in the rim, the tyre middle line is moving between the left and right side of the wheel.
Is there an easy way to centralize the tyre on the rim?
Hello, what if I just simply bumped on a small speed bump and there was no objects around that could really puncture my tire, but it's still flat should I do this?
A little trick: after you get a flat, go see where is in the inner tube and try to locate the same position in the tyre.
The other day I got an invisible thorn inside the tyre and I was able to locate it using this method.
Ran over a bloody pothole while I was looking back at my friend. Blew out my inner tubes and I had to walk all the way back home. Luckily it was just 10 km.
watched this clip last night only to have a puncture on my ride this morning . Suffice to say i was able to sort this out and continued the ride. thank you
Watching this video and at the end I haven't even managed to get my Tyre level in to start taking the Tyre off🙈 is there a trick to that or do I need to start training different muscles to get this right??
came for the content, stayed for the Garmin auto-restart sound! haha
So that tire will self heal or does it also need a fix or replace?
The tutorial is not good, you don’t say how to acctualy fix the tyre
Was having a great ride and 19 miles away from my house and got a flat....wished I watched this video sooner. But will be be prepared if it happens again.
had my first flat today. This helped a bunch! thanks
Helpful video as always.
I'm told that not keeping/using the dust cap falls into Matt's unwritten rules, but I also get a nut on the thread of the valve of the inner tubes that I buy.
It seems like this should go on the outside of the rim, but not really sure?
Short and to the point. Perfect.
Great vid from Dan. Question: how many spares is recommended to bring on a ride? I presume at minimum 1 but have heard others say 2. Where would one store the 2nd one?
Ugh, my tire got punctured by a nail, its stuck inside the rim, I have no spare tubes and I'm freaking out
Is there a place to get those water bottles? I've seen a couple videos and it seemed like you all have hundreds of them.
I got triggered when he called the grass the floor, not the ground
When I was a child I always used to explore my tyres.Since I was a poor child I had to use patch to fix tyres.All I need to get was a small bowl.I used to put my explosed tyres into a bowl and start to cycle it until finding to small hole.if I see a bubble then it means we find the hole so All I had to do was patch it and it was ready to ride.Sometimes I ride.But I will always miss my BMX!!
Nice Cervelo. Is that your favorite brand? I bought an S2 this past December, it's definitely a Rocket.
2:08 so you basically printed your thumbnail, folded it and used it to push against the thorn?
whys tire spelled with a y?
Because we're english, and we spell it with a y.
Global Cycling Network I'm English I spell with I lol
JohnnyUnfiltered why have you spelt "whys" when it should be why's?
