Tire inflation pressure changes with fluctuations in external temperature. Actual "cold" tire pressure indicates changed "cold" tire pressure at given temperature. Overinflated number indicates by how much actual "cold" tire pressure is above the recommended tire pressure. Underinflated number indicates by how much actual "cold" tire pressure is below the recommended tire pressure.

* Estimated calculations and should only be taken as suggestions.

- Vehicle’s recommended tire pressure can be found in vehicle owner’s manual, or on tire placard attached to the vehicle door side, glove box compartment or fuel door.
- Always use tire pressure recommended by the vehicle manufacturer, not the pressure listed on the tire sidewall.
- Tires can naturally lose on average 1 to 2 psi of pressure a month, so check tire pressure regularly.
- Check tire pressure when tires are "cold" and have not been driven for at least three hours. Never adjust tire pressure when tires are "hot".
- Tire pressure changes by about 2.5% for each 10°F difference in temperature. Adjust tire pressure accordingly.
- Underinflated tires can significantly reduce the life of a tire and reduce fuel efficiency of a vehicle by up to 5%.
- Overinflating tires does not increase their load-carrying capacity.
