Check your tires – Hot driving tip from the National Highway Traffic Safety Administration (NHTSA)

Tire Maintenance Icon Inspecting your tires before a trip is one of the most important safety measures to ensure a positive travel experience. Use the following best practices:
  • Keep a tire pressure gauge in your vehicle at all times and check pressure when tires are “cold” — meaning they haven’t been driven for at least three hours.
  • Check tire pressure making sure each tire is filled to the vehicle manufacturer’s suggested PSI (pounds per square inch) of air pressure, which is listed in your owner’s manual and on a label inside the driver’s door. Tire pressure drops as the temperature drops. Properly inflated tires ensure optimum tire performance and optimum vehicle driving range.
  • Check to see that the tread is sufficient with no uneven wear and that the rubber is in good overall condition. Replace tires that have uneven wear or insufficient tread. Tread should be at least 1/16 of an inch or greater on all tires. Look for the built-in wear bar indicators to determine when it’s time to replace your tires or use the Lincoln’s head penny test. Place a penny in the tread with Lincoln’s head upside down and facing you. If you can see the top of Lincoln’s head, you are ready for new tires. Note:tire rubber starts to degrade after several years, and older tires need to be replaced even if they have not seen much wear.
