How to Use Argon to Fill Bike Tires

Argon is a noble gas, meaning it is less reactive than other gases in our atmosphere and is therefore very unlikely to break down butyl tire tubes. This, along with the fact that no ambient moisture will be pumped into a tire tube, has some bicyclists using argon gas rather than traditional tire pumps to inflate their tires. While argon gives a more consistent tire pressure than air, it leaks just like any other gas, and its costliness can deter less advanced cyclists.

Instructions

    • 1

      Remove the cap from your tube's valve stem. If you have a Presta valve, loosen the nut. Deflate the tube as much as possible with the tire pressure gauge.

      Attach the cylinder of argon to the cartridge inflation system. Turn the canister holder the recommended number of turns to poke through the argon cylinder. This number will vary based on the size of the cylinder, the type of canister and the type of inflation system, but once you can hear a hissing noise, you have punctured through the opening.

    • 3

      Attach the inflation device to the valve and lock it in place.

    • 4

      Trigger the inflation mechanism and fill the tube with argon. After a few seconds, stop inflating and remove the inflation system from the valve stem. Press the tire pressure gauge on the valve stem to check the tire pressure.

      Fill the tube to its recommended pressure, which should be noted on the sidewall of your tire. Do not over- or under-inflate. Close the valve nut if the tube has a Presta valve, and replace the cap. Simply replace the cap if you have a Schrader valve. Check the pressure daily to determine if there is a slow leak in your tube.
