Well, as butyl rubber naturally leaks carbon dioxide, I have pumps and fill them regularly.
Tubes are made of butyl rubber.
The permeability of a gas through rubber depends mainly on its
diffusivity and
solubility in rubber.
CO2COX2 has a significantly higher solubility in rubber than O2OX2 and N2NX2, whereas the diffusion coefficients differ not that much.
The result is that carbon dioxide passes ordinary rubber about 5 times faster than oxygen and about 15 times faster than nitrogen
Of course, you could just fill them with nitrogen and reduce the time of filling them up again as often.
