An average range for all tires is between 30 and 35 pounds per square inch, or PSI. But it’s more important to know if this is the correct PSI for your car, which is set by the manufacturer. This is found in your owner’s manual or posted inside the driver’s side door.
This is important because tires that are not properly inflated can suffer serious consequences. You may feel your steering wheel shake or vibrate during driving. Improper inflation can also cause your tires to get out of alignment, which only makes the vibration worse.
Overinflated tires can become deformed with the excessive air pressure. They may not react to potholes or other road hazards properly, or the ride can become harsh and noisy.
It’s necessary to check the air pressure in your tires frequently. Get a good tire gauge and check them about once a month—ask the specialists in our tire shop if you need help! Improper tire pressure can lead to blow-outs on the highway.
