There has been a few studies on this one by the NHTSA in America and one by a professor daws. Both run multiple tests at there are a couple rules to weither or not it is worth it. 1 its measured by the area of the tire (is it big or small) the larger the area the more nitrogen has an advantage). 2 it matters on the humidity of the air, air with high humidity fluctuates in temperature greater, and psi changes more. In a high humidity area the advantages of nitrogen are stronger 3 it depends on the activity of the vehicle, driving around in the city at 25 mph its not all that effective, driving on the freeway all the time its worth it, racing on a track is a must Links to both NHTSA pdf and prof daws study on this page Please read the pdfs for yourself and dont let people tell you wrong information http://bvmotorsports.com/home/learn/wheels-2/nitrogen-filled-tires/
