Rear Tire Pressure

1985 Bentley Continental has original equipment tire size of 235/70R15 for front tires with recommended tire pressure of 24 psi, and original equipment tire size of 235/70R15 for rear tires with recommended tire pressure of 28 psi.

It is important to maintain normal tire pressure for your 1985 Bentley Continental. Low 1985 Bentley Continental tire pressure can cause tire underinflation, and high 1985 Bentley Continental tire pressure can cause tire overinflation. Check 1985 Bentley Continental tire pressure regularly to avoid overinflated and underinflated tires.

Tire inflation value listed on the sidewall of your tire is its maximum tire pressure, and not a recommended 1985 Bentley Continental tire pressure. Use correct tire pressure listed on 1985 Bentley Continental tire pressure chart found on the side of driver's door or in vehicle's manual.

Maintain optimal 1985 Bentley Continental winter tire pressure by adding air to your tires as needed to the recommended tire pressure value.

If your 1985 Bentley Continental is equipped with tire pressure monitoring system (TPMS), keep your eye on low tire pressure warning light being on. Ensure your 1985 Bentley Continental tire pressure sensors are working properly to stay alert and enjoy a safe ride.

1985 Bentley Continental 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
  • 1985 Bentley Continental 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.
