Key Tire Care Messages

  • All motorists need to check their tire pressure at least once per month.

  • You can’t tell correct tire pressure just by looking. Use an accurate tire pressure gauge to measure pressure when tires are “cold” — meaning they haven’t been driven on for at least three hours.

    tire at 32 psi - recommended pressure
    tire at 16 psi - 50% recommended pressure
    Tire at 32 psi
    (100% recommended pressure)
    Tire at 16 psi
    (50% recommended pressure)
  • The correct PSI or pressure for your tires is listed on your vehicle’s tire information label or in your owner’s manual, not what's on the side of the tire.

  • Check the overall condition of your tires, particularly the tread and sidewalls, at least once a month.

  • Use the Lincoln’s head penny test, or look for the built-in wear bar indicators to determine when it’s time to replace your tires.

  • Make note of any irregular tread wear. This could be an indication of a wheel misalignment, the need for a tire rotation, or both. Uneven tread wear is a sign that you need to take your car in for servicing.
