Is CO2 Gas Safe For Tires And Air Tools?
Yes. CO2 vapor is inert (nontoxic and noncorrosive). CO2 vapor is also perfectly safe for tires and wheels. CO2’s thermal expansion rate is similar to air (~1 psi change per 17 degree F temperature change). CO2 is considered a “wet” gas because it does start out in liquid form but the amount of moisture content per cubic foot of CO2 vapor is less than the air emitted from the average air compressor. There is no need to worry about running air tools with CO2 either. Just maintain your air tools to the manufacturer’s recommendations with proper air tool lubricant.
