Why is Tire Pressure Important?

Checking your tire pressure can be crucial for your safety.

Incorrect tire pressure affects responsiveness, traction, and stability. It may also affect your comfort, fuel economy and life of your tires.

If tire pressure is too high, less of the tire touches the ground. This means that traction suffers and it will increase your stopping distance. High tire pressure also causes blowouts and uneven wear.

If tire pressure is too low, then too much of the tire touches the ground. This increases friction and your tires will wear down quicker. There is also a great risk of overheating, which may cause a tire failure and an accident.

Under-inflated tires are bad for your fuel economy. They generally lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires.

It may not seem much, but it equals up to $0.11 per gallon.

The recommended pressure is usually found on a sticker attached to the vehicle door edge or the glove box and in your owner’s manual.

Do not use the pressure printed on the tire’s sidewall. This is the maximum pressure, not the recommended pressure for your car.

Always check pressure when tires are cold.
