Have you checked the tire pressure on your car lately?
This is a green habit that you should try to do regularly. It’s quick, simple and can save you a lot of money while making your car more efficient. It’s something you can even get non-green friends and family to do in the name of saving money, gas prices being what they are.
Having the right amount of air pressure in your car’s tires not only improves gas mileage, it’s better for the tires so they last longer.
Keep the pressure within the range recommended by your car’s manufacturer. They do have reasons for the numbers they quote. Some of it is your comfort, as the more pressure in the tire the firmer the ride of the car, and most people don’t like feeling the bumps that much.
