Has anyone else experienced tires inflated with CO2 slowly losing CO2?
I've had two tires go completely flat before my next ride a couple of days later, but couldn't find the smallest leak after I got them off the bike and they worked fine when reinflated with air. I have also had a couple go soft, but not flat. A fellow biker at my office said he had experienced this also.
CO2 has molecules that are small enough to escape between the tube's butyl rubber molecules. So a tire inflated with CO2 goes flat quicker than one inflated with air.
