A: You should check the pressure in your tires at least once a month. Use a high quality tire gauge. Always check tire pressure when the tires are cold. It is also a good practice to check the tire pressure before long trips. Be sure to inflate your vehicle's tires to the specifications found on the tire placard. Replace the valve stem caps after checking tire pressure.
