Ohio CDL Practice Test

To ensure proper tire pressure, it is important to check the pressure when the tires are cold, typically before driving or at least three hours after the vehicle has been stopped. Hot tires can show an inflated pressure reading due to the heat generated from driving, which can lead to overinflating when adjustments are made based on these readings. Driving with the tires as they are can provide an opportunity to later check and adjust the pressure when they have cooled down, which will give a more accurate measurement. This practice helps maintain the correct tire pressure, promotes tire longevity, improves fuel efficiency, and ensures safety while driving. It is crucial to keep in mind that tire pressure can change with temperature fluctuations, and accurate measurements allow for better vehicle performance and handling.
