I hate to argue with most of you but the NHTSA study goes on to say that the 1.3% loss was on a low PSI tire, as PSI requirements increase so does the rate of loss. Also depends on the area inside the tire, the humidity of the air around you and the change of temperature. Driving at higher speeds causes a higher fluctuation of temperature. If you drive around town at 40 mph in arizona or texas and and you have small tires that are normally inflated to 35 psi then its a small change. If not it could be a big change, please read the articles for yourself instead of taking someones word for them.
