Have you done this to increase MPG?
Long story short I am at a local tire store getting a tire patched, and strike up a conversation with the manager. He asked me how long its been since I've had the air in my tires flushed, and was surprised when I said never.
He explained that air gets dirty over time and the debris in the air causes a large reduction in MPG. For $100 (they normally charge $150) they flushed the air in all of my tires and filled it back up with air pumped through their filter which eliminates 99.99% of debris.
Anyways, got my tires patched and new air in my tires for $150, not a bad deal if you ask me. I will post MPG results next week to see how much they increase by.
