1996 Aston Martin DB7 tire inflation pressure changes with fluctuations in atmospheric 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.

All calculations are based on recommended tire pressure set at 68 °F or 20 °C.

Tire Pressure Tips
  • 1996 Aston Martin DB7 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.
