CO2 air - do I need to change it? seriously..._sprocket_

i was told to 'change' the air in my tire if it was inflated using a CO2. is this necessary?
yes; it leaks out much more quickly nmDougSloan

If you inflate your tire with CO2 today, it will be flat tomorrow morning. Do it now, or do it tomorrow.

despite all the empirical evidence here about "flat by tomorrow" I have not experienced it. I've seen soft, but never flat by the next day. Might have to do with living at high altitude, but who knows.

I don't ever change it out, I just top off before every ride. It does not leak out so rapidly that you'll go flat on a subsequent ride. So, if you're in the habit of always checking and filling before you go out (regardless of a recent CO2 refill,) you'll be fine.

I had a flat and filled the spare with CO2. Guess what? It was flat the next morning. Fill it now or fill it later but you'll have to fill it sometime.

Repaired a flat with CO2 on Saturday, yesterday it was soft but not flat. In fact, it still had about 60 lbs. of the 90 lbs. I put in with the cartridge.

No argument that it leaks and that you need to replace it, but in my (extremely personal) experience, I've not had to ride home, let the CO2 out and put in air. I've (personally) never had one go flat overnight. If you top it off before each ride, the replacement can be self-fullfilling.

Maybe because I live at 5k+ feet?

I had a flat two weeks ago also. I filled the spare with CO2 and haven't noticed any increased leakage, etc. That's why I posted the question. I've always heard you need to change the air, but nothing seems to be happening. I'll probably change it just to be on the safe side.
Top off when you get ready to ride and you'll be fine (nm)terry b

Now is the time we dance?
yes, and rotate the air in your tires every 500 miles (nm)tarwheel
