Summer Driving Tip:Save $200 in Gas by Checking Tire Pressure!

By: Scott Siegel


One of the quickest ways to rob a car of efficient gas consumption is to neglect the tires. There are a number of different ways tires can affect your car's fuel saving performance. Making sure you are riding on properly inflated tires is probably the easiest way to save money on gas.

According to statistics provided by the Environmental Protection Agency and the Energy Information Administration, the Possible savings of avoiding under inflated tires is between $100.00 to $200.00 per year depending upon how much you drive and how under inflated your tires may be.

According to the Canadian Office of Energy Efficiency twenty-three per cent (23%) of vehicles have at least one tire under-inflated by more than 20%. Not only do under inflated tires on your vehicle hurt your fuel consumption it can also lead to poor or delayed braking, steering and acceleration. In other words, under inflated tires can be dangerous. Under-inflated tires may squeal when stopping or cornering even at moderate speeds, particularly on warm pavement.

Driving a car with just one tire under inflated by (8 psi) or 20% can lower the car's fuel efficiency by 4%. In addition under inflation may reduce the life of the tire by more than 9000 miles. Tires are permeable. That means that air can and does pass through the tire walls. A tire could lose up to 2 pounds of pressure per month. This is more important in summer as more air permeates through the tire in hot weather as the pores in the tire material get larger in the heat.

Since heat can accelerate air loss in a tire, it is important to note that when a tire is under inflated, the tire flexes and bends more than it would normally. The extra flexing and bending builds up heat. With the additional heat a tire that is under inflated will lose air at greater and greater rate.

There is more bad new concerning under inflated tires and gas consumption. Under inflation also causes the tire to increase rolling resistance. That means the motor has to work harder to move the car and that also increases fuel consumption. Also the extra flexing and bending can weaken the tire walls which could lead to sudden tire failure.

Measure the air pressure in your vehicle's tires at least once a month in order o maintain proper tire inflation levels. When you do measure your tire pressure you need to do it when your tires are cold. "Cold" means that a car has not been driven more than 1 mile or has been stationary for at least three hours.

It is a great idea to keep a pressure gauge in your car. Check the air pressure of the tires often. If you can keep your tires at the correct inflation levels you should realize a savings of between $100.00 and $200.00 per year in fuel. Although proper tire pressure will save you gas and money, it could also prevent tire damage that could lead to accidents. Not only will you be contributing to your fuel economy you will be maintaining the safety of your vehicle.
