It’s important to have the proper inflation pressure in your tires, as under inflation can lead to tire failure. The “right amount” of inflation for your tires is specified by the vehicle manufacturer and is shown on either the vehicle door edge, door post, glove box door or fuel door. It is also listed in the owner’s manual.

Look for this information in your vehicle:

  • Check pressure at least once a month and before long trips.
  • When you check the inflation pressure, make sure the tires are cool — meaning they are not hot from driving even a mile. (NOTE: If you have to drive a distance to get air, check and record the tire pressure first and add the appropriate inflation pressure when you get to the pump. It is normal for tires to heat up and the inflation pressure inside to increase as you drive. Never “bleed” or reduce inflation pressure when tires are hot.)
  • Remember to check the spare. (NOTE: Some spare tires require higher inflation pressure.)
  • Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.


Under inflation or overloading creates excessive stress and heat, and can lead to tire failure. This could result in vehicle damage and/or serious injury or death. An over inflated tire can cause uneven wear in the center of the tread. Over inflation also can
make the tire more susceptible to road hazard damage and pose vehicle handling issues.
