How do I know if my tire needs air?
assistant
The best way to tell if your tire needs air is to check the sidewall of the tire. If it feels soft and spongy, it likely needs air. You can also listen for a hissing sound coming from inside the tire. Finally, you can look at the tire pressure indicator on the vehicle's dashboard or refer to your owner’s manual for specific instructions about how often to check and fill your tires.
