For tire air pressure, what is the correct method to ensure it meets standards?

Using a gauge to check tire air pressure is essential for ensuring that the tires meet the required standards. Gauges provide an accurate measurement of the air pressure within the tire, which is crucial for safe vehicle operation and optimal performance. Properly inflated tires help in maintaining good traction, fuel efficiency, and even tire wear, reducing the risk of blowouts and other tire-related failures.

A visual check alone may not provide an accurate indication of tire pressure, as tires can appear adequately inflated even when they are not. Inflating to the maximum pressure listed on the sidewall of the tire may exceed the recommended pressure for safe operation, which can lead to handling issues and increased tire wear. Checking tire pressure after driving can also yield inaccurate results since heat generated during driving can increase tire pressure, giving a false reading. Thus, using a gauge is the most reliable and effective method to ensure tire air pressure meets the necessary standards.
