We often receive the question: "What should the air pressure in my tires be?" The importance of maintaining the correct tire pressure can’t be overstated. It's crucial for your vehicle's overall performance, fuel efficiency, and safety. The great news is that finding the answer is easier than you think. Let’s dive into this question and other tire pressure-related questions.

How to Find Your Car’s Recommended Tire Pressure

You can look for your vehicle’s recommended tire pressure information in two spots:

  • On a placard or sticker on the driver’s side door jamb
  • In your vehicle’s owner’s manual

If you still need help finding the information, consider consulting a professional. A mechanic or tire specialist will be able to provide you with the recommended tire pressure for your vehicle.

Does Temperature Affect Tire Pressure?

Yes, temperature affects the tire pressure. Generally, for every 10ºF change in air temperature, your tire's pressure will usually change by about 1 psi (pound per square inch). In colder temperatures, air contracts and causes the tire pressure to decrease, which is why you might see the tire pressure warning light come on in the winter months. Conversely, in hotter temperatures, air expands and can cause the tire pressure to increase.

Does Correct Tire Pressure Matter?

Yes. When tires are properly inflated, your car will handle better, and that’s no small thing! According to the National Highway Traffic Safety Administration (NHTSA), vehicles with underinflated tires are three times more likely to get into crashes related to tire problems.

In addition to improved handling and safety, maintaining the right pressure can also offer financial benefits by:

Signs You Need to Inflate Your Tires

Below are a few signs that may indicate your tires are underinflated:

  1. Your car isn’t handling well
  2. Your ride is less smooth
  3. It takes longer to stop
  4. You see cracks in one of your tires
  5. Your tires are wearing out faster than usual
  6. The steering wheel is shaking or vibrating
  7. You hear the signs of misalignment (like noisy steering or squealing stops)

If you notice any of these warning signs, inspect your tires. You can ensure all four tires are properly inflated by testing the tire pressure using a tire gauge.

How Often Should I Check the Tire Pressure?

At a minimum, check your tire pressure once a month. Some drivers check it every time they stop for gas. To get an accurate tire pressure reading, keep these tips in mind:

  • Consistency is important, so try to use the same handheld gauge every time. You can pick one up at your local auto parts store and stow it in your glove compartment for convenience.
  • You’ll get the most accurate tire pressure reading when your tires are cold. Since heat can increase both temperature and air pressure, testing first thing in the morning may be best.
