Tires support the weight of vehicles and provide secure contact with the pavement. The appropriate pressure, measured in pounds per square inch (psi), is crucial for ensuring secure handling and preventing auto repairs following flats or blowouts. Below, you’ll learn more about the importance of proper tire pressure and how to ensure the psi is correct.

Why Is Tire Pressure Important?

Keeping your tires inflated to the right pressure improves stability, handling, and comfort while you drive. Under-inflated tires do not respond as quickly to braking, which can lead to accidents. The rotors and calipers will sink into the loose rubber, preventing them from applying the correct amount of pressure for deceleration and stopping. 

Additionally, under-inflated tires do not spin as fast, which keeps your vehicle from reaching the right odometer speeds. The tread will also deteriorate more rapidly, as the vehicle’s weight bears down on the rubber against the road. This makes tires more vulnerable to punctures, flats, and blowouts. 

It’s also possible for tires to become over-inflated. Though less hazardous overall, tires with too much air in them wear down quickly at the center of the tread pattern, meaning you’ll need to replace them sooner. 

How Do You Check the Pressure?

Unscrew the valve stem cap and place the round end of the gauge over the stem, pressing down to keep air from escaping. Read the numbers on the digital screen or the line on the manual gauge.

If the pressure is beneath the manufacturer’s suggested psi, use an air pump at a gas station to fill the tires. They often have built-in gauges that let you know when you’ve filled to the right pressure.

For over-inflated tires, attach the opposite end of the gauge to the valve stem to release air. Check the pressure and repeat until the gauge shows the correct psi.
