Rear Tire Pressure

2010 Audi A4 2.0T Prestige has original equipment tire size of 245/40R18 93 H for front tires with recommended tire pressure of 46 psi, and original equipment tire size of 245/40R18 93 H for rear tires with recommended tire pressure of 46 psi.

It is important to maintain normal tire pressure for your 2010 Audi A4 2.0T Prestige. Low 2010 Audi A4 2.0T Prestige tire pressure can cause tire underinflation, and high 2010 Audi A4 2.0T Prestige tire pressure can cause tire overinflation. Check 2010 Audi A4 2.0T Prestige 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 2010 Audi A4 2.0T Prestige tire pressure. Use correct tire pressure listed on 2010 Audi A4 2.0T Prestige tire pressure chart found on the side of driver's door or in vehicle's manual.

Maintain optimal 2010 Audi A4 2.0T Prestige winter tire pressure by adding air to your tires as needed to the recommended tire pressure value.

If your 2010 Audi A4 2.0T Prestige is equipped with tire pressure monitoring system (TPMS), keep your eye on low tire pressure warning light being on. Ensure your 2010 Audi A4 2.0T Prestige tire pressure sensors are working properly to stay alert and enjoy a safe ride.

Tire Pressure Tips
  • 2010 Audi A4 2.0T Prestige 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.
