CDL · Night and weather

After a long run on a hot day, your tire pressure reads higher than normal. Which statement is accurate?

Correct answer: Leave the air in, or the tires will be too low once they cool.

Answer options

  1. AReplace the tires, because a high reading means they are damaged.
  2. BLet some air out until the gauge shows your usual pressure again.
  3. CLeave the air in, or the tires will be too low once they cool. Correct

Why

Air pressure naturally rises as a tire heats up, so a high reading on a hot tire is expected. Letting air out would leave the tire too soft once it cools, and if a tire is hot enough that you cannot touch it, stay stopped until it cools so it does not burst or catch fire.
