CO2 Calculator

by Wes Garland,

Many thanks to Harold of the Ninja 250 RC Forums, for getting the math right!


Fill in the size of your tire and CO2 cartridges, and your target tire pressure below. The calculator will help you determine how many CO2 cartridges you should carry to fill a deflated tire which has been repaired with an emergency plug or a patch kit. Note that you cannot seat the bead with these inflators, so the tire must stay on the rim.

Caveat Inflator:



Tire Size (e.g. 130x90/16): x /
Mass of CO2 per cartridge: g
Target Pressure: PSI
