I was shocked when I saw this today while putting in gas. If you can’t read it, it says, “If every U.S. driver had properly inflated tires, over 700 million gallons of gas could be saved each year.”
That’s one big number.
After the shock subsided I thought about for a bit. There’s roughly 300 million living in the US. If, I’m totally estimating, 80% drive (which I think is an overestimation), that’s 240 mil drivers. That equates to less than three gallons a year per person.
When I came home, I decided to look deeper into it. According to the US Department of Energy, the US used 140 billions gallons of gas in 2004. Inflating tires is .5% of that.
Don’t get me wrong, every little bit counts. Continuing to read on the sign, you’ll find that Mobil is just advertising it’s new tire liner technology. If they were really concerned about gas wasted, they’d offer to fill your tires for you every time you put in gas.
If there was anything to really pick at, it’d be traffic. A 2002 Urban Mobility survey showed that each Los Angeles driver waste 94 gallons of gas in traffic.
