Potholes can knock your pressure down. This isn’t one to take lightly either. After an unusually long, brutal winter for much of the U.S., and more snowfall than usual, many cities are in the midst of a pothole crisis. Even if there’s no vibration after an impact and the tire and wheel look intact, the jarring impact of a pothole can temporarily break the seal of a tire to the wheel, causing a sudden loss of some but not all of the pressure—in amounts that might not be enough to set off tire-pressure sensors. If hitting severe potholes is a daily occurrence, remember to check your tires—and tire pressure—as often as you can.
