Usage Scenario

Sarah noticed her car felt a little sluggish on the morning commute. She pulled out her keychain tire gauge, checked all four tires, and found the front left was 8 PSI low. A quick stop at the air pump fixed the issue, and her car drove smoothly again. Now she checks pressure every other week and has seen a small improvement in her gas mileage.
