Helping you get better gas mileage, save money on fuel, find more efficient cars, and be kinder to the environment.

The temperature has been going up and down lately. Remember that changes in temperature cause changes in tire pressure and that changes your fuel economy.

The unusual temperature swings have been over 60 degrees between minimum and maximum in the past few weeks in some areas. That can mean over 5 PSI change in the air pressure in your car’s tires. Underinflated tires hurt gas mileage and can be unsafe to drive on. Overinflated tires handle harshly, wear excessively, and can be unsafe to drive on.

For best fuel economy, check your tire pressure regularly and set it to the pressure recommended in your owner’s manual or on the sticker on the rear of your open driver’s door.
