Tires are an important vehicle part to maintain. Besides checking the tire tread, you should also check the air pressure regularly. Because air pressure changes with temperature shifts, seasonal changes may mean your tires are over- or under-inflated.
According to U.S. News & World Report, you can find the right tire pressure for your car on the driver-side door jamb behind the seat. There should be a chart that lists optimum tire pressure. It’s important to note that this may vary from the number listed on the tire itself. If there’s a discrepancy between the two numbers, follow the chart on the door jamb.
For every 10-degree drop in temperature, the air pressure will drop by 1 psi. The opposite is true in warm weather; the hotter the temperature, the more pressure. Tires may also simply lose pressure over time.
You can easily check and fill pressure with a tire-pressure gauge, but many new cars will also automatically alert you when the tire pressure is low. Most gas stations will have air pumps, if you don’t have one yourself. It’s important to fill tires because underinflated tires will tend to cause added friction, leading to blow outs and reduced fuel economy. Overinflated tires can ride improperly, also causing blowouts or uneven wear.
