According to the National Highway Traffic Safety Administration, under-inflated tires have a higher risk of damage and failure. Not only will they wear out faster if under-inflated, but faster deterioration can also lead to reduced control of your vehicle, tire blowouts, and crashes.
In addition to safety, there's also an environmental and economic benefit to keeping your tires full of air. Gas mileage is reduced by .2% for every 1 PSI (pound per square inch) your tire pressure
drops below the recommended level. By keeping your tires inflated to the proper pressure, you could save yourself up to 3% in gas mileage, depending on your vehicle and driving habits.
Not only are you saving more money in reduced visits to the gas pump, but you're also ensuring our planet continues to grow and thrive for drivers of the future.
