Is there any adverse effects of running pure CO2 in the tyres? From fish keeping I know that silicone tubing is permeable to CO2, other than that, CO2 seems to be a mostly inert gas. I'm asking because I've got a 20lb tank of CO2 sitting in my bedroom, trying to figure out what it can be used for besides feeding aquatic plants.
Some advantages of running CO2:
- no moisture, consistent temp/pressure change
- easy road-side refill (on trips)
- won't be able to use it as a breathing apparatus, as seen in die hard
