How Long Does It Take to Fix a Bike Flat Tire?

If you are cyclist and have not yet had a “road flat”, you will. If you are an experienced cyclist wondering how long it should take to change a flat tire, this article is for you.  Getting a flat is a bummer, and disrupts your ride.  All the more reason to invest in a durable bike tire, but even if you do there will inevitably be the occasional flat.

There are so many different things that can affect how long it takes to change a bike tire that it can vary tremendously. Much of it depends on the person involved and if they have changed a tire before. Someone who is experienced and has been riding for years, know exactly what they are doing it can take as little as 7 minutes, but a new rider who has never changed a tire, and never really worked on a bike before, it can take a lot longer, up to 20 minutes and perhaps more.

Clinchers and tubular tires require a different changing method. This article is about clinchers – they are more common.

The other thing that affects how long it takes is the tire itself, whether it is a tubeless or tubular tire or not can change things, and whether it is a front or rear tire that needs changing matters as well. With the front tire, removal is simple for anyone, a rear tire can be trouble for those not familiar with how the gear systems on bikes work as removing the rear wheel involves the chain mechanism.  As for they type of tire, there are many different types of bike tires out there.  This article is focused mainly on changing a clincher tire, which is the most popular kind.

Fixing a flat is actually straightforward though, and is something every rider should master, so here are the steps:

Remove the wheel

Undo the quick release and slide the wheel out of the bike, for the front wheel this is simple, but for the rear wheel take care with the chain, make sure to unhook it from the when first. Total time: 30-60 seconds.

Inspect for the puncture

Before taking the tire off the wheel, see if you can find the cause of the flat. Often this is a sharp object that has punctured through the tire and into the tube, and should be visible. Pull it out before doing anything else, you don’t want to leave it in the tire and puncture the new tube as soon as you inflate it. It is possible to have a hole in the tire but still be able to ride it on a new tube, assuming you have removed the source of the puncture. In this scenario, you will want to eventually replace the tire. Total time: 1-2 minutes.

Remove the tire

Use a bike tire tool to remove the tire.

Next is taking the tire off the wheel, and for this you need a couple of tire levers. These are cheap little plastic “wrenches” intended for bike wheels without damaging them. Never use metal or a screwdriver!  An aluminum rim is much softer than most metals and would bend or chip easily if you try to pry a tire off with the wrong materials.  Carbon fiber is even more delicate — the wrong material used on it could really run a high-end rim.

This is the part that people often struggle with the first few times, but once you get the hang of it, you can do this in a few seconds. Take the first tire lever, and slip the flat end under the edge of the tire (called the bead), lifting it away from the wheel. Pull down to level it out from the wheel and hook the other end around a spoke to keep it secured in that position. Now take the other tire lever, using the flat end, insert it into the gap between tire and wheel you just made, and then slide it around the rest of the wheel to dislodge the tire all the way around. The first little bit is the hardest. Once loose, take the tire completely off, and then pull the damaged inner tube out as well. Total time: 2-3 minutes

Inspect the wheel and tire

If you hadn’t previously found the cause of the puncture, check the wheel and inside of the tire to find the problem and remove it. If the tube has two holes side-by-side, like a snakebite, then that is what is known as a pinch flat, caused by the tube not being inflated enough. Shake the tire in case a small rock got inside and caused the puncture.  Note that if you see a sidewall blowout — a large gash in the side of the tire — it likely means the tire is destroyed.  Short of some advanced hacks, it is unlikely you will be able to ride it home.  Those are a small minority of flats, though. Total time: 1-2 minutes

Install the new tube

Put one side of the tire back on wheel, add a little air to the tube so it has some shape, and then begin tucking the new tube under the tire and seating it to the wheel. Start at the valve hole and work around until all the tube is seated to the wheel and inside the tire. Then, roll the other side of the tire back on the wheel, taking care not to pinch the tube underneath it at any point. Total time: 2-5 minutes

Inflate the tire

CO2 inflators are the way to go if you are on a road bike and trying to keep your load light.

Inflate the tire to the required pressure using your pump, take it steadily and check the tire is seated properly as you go. If you are not carrying a pump (many don’t because even small ones can be bulky) then be sure you have CO2 cartridges. They are slick little capsules that allow you to easily pump a tire on the go. You put a little nozzle on the end and attached it to the valve. Unscrew the nozzle half a turn (other types require you to bend or push a button on the inflator) and the tire will begin inflating. Finally, reattach the wheel to the bike, again, if it is the rear one, ensure the chain is refitted correctly as well. Note that you should always pump the tire again when you are back home – the CO2 cartridge is just intended to help you finish your ride. The tire is likely a bit underinflated. Total time: 1-3 minutes

Supplies You May Want

A small kit of inexpensive supplies will help you fix a road flat whenever you have one.  You don’t need to spend much — it is really just a cheap insurance policy that you really need to have.

  • A spare tube.  Make sure it has a compatible size with the tires you ride.  Like this one.
  • Tire removal tools.  You can get by with one, we like to have two.  It makes the job much easier.  Like this one.
  • CO2 nozzle. Compatible w/ the cartridge.  Like this one.
  • CO2 cartridge.  They are not big.  We like to carry two (you only need one nozzle, though)  Like this one.
  • Small supply bag.  If you can carry this stuff in your backpack or jersey.  Like this one.

We will be happy to see your thoughts
