This is a reprint from Volume 8, Issue 3 of Bridgestone Real Answers. It effectively explains the benefits of filling your tires with nitrogen. They do a great job of detailing the effects of water vapor in compressed air, and why nitrogen is a better solution to this issue.
When you consider that Bridgestone and other tire companies have the most to lose if nitrogen inflation extends tire life, it is easy to see why this is such a powerful piece of information. It is usually the first piece of literature I use when discussing the advantages of nitrogen filled tires, and thought you may find it beneficial. Enjoy.
