Rear Tire Pressure

2015 Alfa Romeo 4C has original equipment tire size of 205/45R17 88 Y for front tires with recommended tire pressure of 26 psi, and original equipment tire size of 235/40R18 95 Y for rear tires with recommended tire pressure of 29 psi.

It is important to maintain normal tire pressure for your 2015 Alfa Romeo 4C. Low 2015 Alfa Romeo 4C tire pressure can cause tire underinflation, and high 2015 Alfa Romeo 4C tire pressure can cause tire overinflation. Check 2015 Alfa Romeo 4C 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 2015 Alfa Romeo 4C tire pressure. Use correct tire pressure listed on 2015 Alfa Romeo 4C tire pressure chart found on the side of driver's door or in vehicle's manual.

Maintain optimal 2015 Alfa Romeo 4C winter tire pressure by adding air to your tires as needed to the recommended tire pressure value.

If your 2015 Alfa Romeo 4C is equipped with tire pressure monitoring system (TPMS), keep your eye on low tire pressure warning light being on. Ensure your 2015 Alfa Romeo 4C tire pressure sensors are working properly to stay alert and enjoy a safe ride.

Tire Pressure Tips
  • 2015 Alfa Romeo 4C 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.
