How to Put Air in Bike Tires Without a Pump | 3 Methods!

Pumps are essential tools for any bikers as they are the most straightforward solution regarding inflating tires. And most bikers use a pump for their tires on a regular basis. But there are times when we aren’t able to get pumps for our bike tires. And knowing how to put air in bike tires without a pump really comes in handy in those situations.

And in this article, we will introduce you to some of the most useful methods that you can use to inflate your bike tires without using a pump. So, without further ado, let’s dive right in, shall we?

How to Put Air in Bike Tires Without a Pump

How to Put Air in Bike Tires Without a Pump

Now there are quite a few methods that you can try for putting air in bike tires without a pump. But not all of them are the best option. From our research, we have concluded that there are three options that you should consider when planning on putting air in bike tires without a pump. These three options are:

  1. Using Carbon di Oxide Cartridges
  2. Using Air Compressors
  3. Manually Blowing Up the tires

There are also other options, but they aren’t that useful or budget-friendly for bikers in general.

Method 1: Using Carbon di Oxide or CO2 Cartridges to Inflate Bike Tires

This is the best alternative option that you can choose instead of employing a pump to inflate your tires. But that being said, always remember that using CO2 cartridges is just a temporary solution when you don’t have a pump nearby. Because as we all know, carbon dioxide is bad for the environment, and we should always try to steer clear from using them whenever we can.

And as carbon cartridges are very small in size, it is easier for you to carry them than carrying a pump for yourself.

Now that being said, here are the steps that you will need to follow in order to inflate your bike tires with the help of Carbon di Oxide (CO2) cartridges:

Step-1: Check the Bike’s Tube & Tire Sealant

This is one of the most essential parts that many bikers tend to forget when inflating their tires. Because the tube is facing problems or the bike tire sealant is out of order, then your tire will flatten just a few moments after you have filled it with air.

Therefore, make sure that the tire’s tube and sealant are functioning properly and only the air pressure has been compromised. Also, remove the gravel bike pedals as they can get in the way sometimes. Now, you can proceed to the next step.

Step-2: Removing the Cartridge’s Cap

The next step is the removal of the cap of the cartridge. For that, first, turn the cap anti-clockwise. This process can easily be done with your hands. Once the cap is removed, proceed to collect the cartridge and inflator fitting from the tube. You can do this once you tip the other side of the inflator up.

Step-3: Putting the Air into the Tires

First, insert the cartridge into the tire; once adjusted, start to push it clockwise. You will notice and will also hear the airflow starting. Now, hold and wait a few moments until your tire is filled with air. This will vary depending on your tire’s nature and type.

Once the tire is filled with air, you need to stop the airflow. In order to do that, you should rotate the cartridge counterclockwise until you hear the air stops flowing. And voila, your tire is filled with air.

This is one of the most delicate steps that you will need to undergo. As correctly filling the tire with air is crucial. Too few, and you will risk a flattened tire, too much, and the result is the same. So, be careful.

Step-4: Removing the Cartridge

Now, you should never leave the cartridge fitted with the inflator. And removing it is very simple. Just unscrew it from the inflator fitting. Also, close the nozzle once you have pulled the nozzle away from the valve.

Step-5: Replacing the Carbon di Oxide with Air

Carbon dioxide is a temporary solution for getting your tires fixed in a tough situation. They shouldn’t be the replacement of air in your tires. So, as soon as you get the chance. Change your tire’s air with a regular pump because carbon dioxide is just too risky.

And there you have it. If you follow these mentioned steps correctly, then you can quickly inflate your tire using carbon cartridges, and you won’t need a pump at all.

Method 2: Using Air Compressors to Inflate Bike Tires

Air compressors for bike tires are another great option if you want to inflate your bike’s tires without a pump. The steps that you need to follow are very easy, and this method is highly preferred for mountain bikes with tubeless tires. The steps that you will need to follow are:

Step-1: Checking Your Bike Tire Sealant

As previously mentioned in the carbon cartridge method, checking your bike tire sealant is very important because if it is faulty, then you risk the chance of setting your tire up for flattening sooner than later. So, make sure that your tire sealant is working properly.

Step-2: Putting the Inflator into the Valve

Next, open the presta valve of your tire and put the inflator in. Make sure to power on the air compressor beforehand so that when you put in the inflator, you will immediately see the tire beads jumping up, right into place with a ‘pop’ sound.

Step-3: Filling the tire with Air

Aim compressors generate air faster than pumps, so remember that when filling your tire with air via an air compressor. Once you feel that your bike’s tire has been filled. Immediately pull out the inflator and adjust the valve of your tire.

Many do the opposite and try to turn off the air compressor first. That is a mistake because some remnant air will still be getting out of the inflator after the compressor is powered off. This can largely imbalance the air pressure of your tire. So, be very careful and avoid this mistake at any cost.

And this is the way you can inflate your tires using air compressors. Using mountain bike tubeless tires for this type of inflation is the best as tubeless tires require a low amount of air to begin with.

Method 3: Manually Blowing Up the tires

This is the last method that you should try if you don’t have the option to go for the previous to mentioned methods for putting air into your bike’s tires without a pump.

The process is very simple. You will need to put air into the tires using your mouth. The steps that you should follow are:

Step-1: Cleaning the Valve

As you are putting your mouth into the valve. It is best to clean the valve beforehand. Use a cloth to clean the valve before you begin to put your mouth in.

Step-2: Blowing into the Valve

Once you open the valve, put it into your mouth and start blowing air into the valve. You shouldn’t use too much force, or you will be out of breath very fast.

Step-3: Holding the Air

Once you are out of breath, you need to refill your lungs before you can start blowing air into your tires. And in order to do that, you will need to hold the air that you’ve blown into the tire.

To do that, use your tongue to cover up the valve entrance, and you are good to go. Do this process a couple of times, and you will see your tire is being filled with air very soon.

And this is how you can fill your tire with air by manually blowing air into your tires.

Frequently Asked Questions

1. What size of Carbon Cartridge should I take with me?

It depends on your tires and their capacity. Generally, a 25-gram carbon cartridge is enough for filling both tires of a mountain bike. But that’s not the same for a road bike, though. So, check your tire manufacturer and details to determine which amount of carbon cartridge is best for you.

2. Is it safe to put my mouth in a tire valve?

If it is properly cleaned, then putting your mouth in a tire valve should be safe. But you should always clean your tire valve beforehand.

3. Should I replace the carbon dioxide in my tire?

Of course, you should never keep carbon dioxide as air in your tires.
