Mcihelin tireLet's say that your vehicle's tires are nearing the end of their useful life. Looks like you're in need of standard replacement tires then, right? Well, instead of opting for a conventional tire you could save fuel by picking up a set of low-rolling resistance tires.

Low-rolling resistance tires minimize energy wasted as a vehicle moves down the road, thereby improving fuel efficiency. Approximately five to 15 percent of the fuel consumed by a typical car is used to overcome rolling resistance. Therefore, by reducing rolling resistance, fuel consumption drops.

Okay, low-rolling resistance tires reduce fuel consumption, but how much gas are you likely to save? A drop? An ounce? Gallons? Well, the California Energy Commission (CEC) estimates that equipping a vehicle with a set of low-rolling resistance tires reduces fuel consumption by 1.5 to 4.5 percent.

Let's recap: low-rolling resistance tires reduce fuel consumption. Reduced fuel consumption means less dependence on foreign oil and more money left in your bank account after gassing up. That's a win-win combination. Don't you think?

Note: To mark the 41st anniversary of Earth Day* this year on April 22nd, we're running a series called Countdown to Earth Day that we want to be very welcoming to new readers, both in topic and tone. We'll be returning to our Greenlings series for inspiration here, and if you have friends who you'd like to introduce to AutoblogGreen, perhaps these posts and the coming "holiday" will be the spark to get their green car fire burning.

*Ironically, the apparent traditional gift for a 41st anniversary is land. Since land - earth - is something we can't easily create, perhaps this Earth Day we can give ourselves the gift of stewardship of the land.
