We could go to the Innovations (the company that sells the stuff) web sight, or read the instructions. That would tell us that the molecules are smaller and leak out of the tube faster.
Sorry, I know real men don't read instructions. I apologize.
The leak rate is not an issue of molecule size. I don't think there is any question that a CO2 molecule is larger than an N2 or O2 molecule. Besides, it's hardly in Innovations best interest to volunteer that using their product will result in a flat tire a couple days later!
