Thread Name: BS: Nitrogen in your Car Tires? Bull Or Not
Subject: RE: BS: Nitrogen in your Car Tires? Bull Or Not
Even if the tank used to inflate the tire contained 100% Nitrogen, it would be near impossible to fill a tire to the 100% level. The tire would need to be completely evacuated first. Just letting the air out and re-filling with Nitrogen might be 90% effective (or better) but not completely. You will still some oxygen as well as trapped water vapor.
