Different tires are filled with different carbon dioxide cartridges

The smallest bicycle tire inflator is a CO2 cartridge. Any type of bike tire, including road bike tires, mtb bike tires, and fat bike tires, can use it.

Depending on the size of the CO2 cartridge and the type of bike tire, it can fill a certain number of tires. Threaded co2 cartridges and non-threaded co2 cartridges are the two forms of co2. There are different sizes of CO2 cartridges available; the smallest size is a 12 gram CO2 cartridge. The market then offers sizes of 16 grams, 20 grams, 25 grams, and a few others.

A road bike tire can be inflated with a smaller 16-gram co2 cartridge. Two road bike tires or one mountain or fat bike tire can be filled with a bigger 20 gram CO2 canister. Additionally, if the CO2 is 25 grams, it can fill two 29-inch automobile tires, fat bike tires, or mountain bike tires.

A little co2 tire inflator can fill up to 130 pressure, which is adequate to fill one road bike tire. A road bike tire or standard bicycle tire needs up to 120 psi.  

How many co2 cartridges are necessary to fill a mountain bike tire?

Depending on the size and width of the mountain bike tire, you will need a certain number of CO2 cartridges to fill it. Three different adult mountain bike sizes with varying pressures are available: 26 inches, 27.5 inches, and 29 inches. A mountain bike with a 26-inch wheel requires a minimum of 30 pressure, a 27.5-inch bike requires 25 psi, and a 29-inch tire requires 31 psi.

Since a 16 gram cartridge will only fill a tire to a pressure of 15 psi when flat, you will need two of them to fill a mountain bike tire, which typically has a pressure range of 22 to 40 psi.

One CO2 cartridge inflator, however, is sufficient to inflate a mountain bike tire if it is a large 20-gram or 25-gram CO2 inflator.

How many co2 canisters are needed to fill a road bike tire?

Although a road bike tire doesn't go flat as frequently as an mtb or fat tire bike, it might occasionally go flat and need to be inflated. Road tires can be inflated with a hand pump, small pump, or CO2 cartridges. A pressurized carbon dioxide mini-inflator called CO2 is smart. It will save you time and quickly fill your tire. How many CO2 canisters are required to fill a road bike tire?

Road bike tires can be filled using just one 16-gram CO2 cartridge. A 16 gram co2 cartridge can deliver up to 130 pressure to a road bike, whereas a conventional road bike requires 90 to 120 psi of inflation.  

What happens, though, if both tires need to be filed? Then, what will you do? To fill all four tires, you will require 340 pressure, or up to 120 psi per tire, which a single 16-gram cartridge cannot deliver. So either two 16-gram cartridges or a huge 20-gram cartridge are required.

How many co2 cartridges to fill a fat bike tire?

To provide the best level of grip, a fat bike tire has a broader footprint, and it requires more air pressure to handle tough terrain. It depends on the size and width of the wheel whether you need one or more CO2 cartridges to fill a fat bike tire. You will need less cartridges to fill a narrower tire than a larger tire, and vice versa.

A fat bike tire's width ranges from 3.7 to 5.2 inches. To fill a fat bike tire, you will either two 16g cartridges or one large 25g cartridge. A huge 25-gram co2 inflator can achieve 7.5 psi in a fat bike tire (26 inches wide).

A 38 g co2 cartridge is also an option if you don't want to take any chances. It is able to inflate 293.0 tires to 20–22 psi and 264.8 tires to 6-7 psi.
