Estimated calculations and should only be taken as suggestions.

2012 Infiniti G37 Base Model tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.

2012 Infiniti G37 Base Model tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.

2012 Infiniti G37 Base Model tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.

Tire Pressure Tips
  • Recommended tire pressure for 2012 Infiniti G37 Base Model tires can be found in vehicle owner’s manual, on sticker placard on driver's door jam, inside glove box compartment or fuel door.
  • It is important to use tire pressure recommended by the vehicle manufacturer, not tire pressure listed on tire sidewall.
  • 2012 Infiniti G37 Base Model tires can naturally lose on average 1 to 2 psi of air pressure monthly, so check tire pressure regularly.
  • Check 2012 Infiniti G37 Base Model tire pressure when tires are "cold" and have not been driven for at least three hours. Never adjust tire pressure when tires are "hot".
  • 2012 Infiniti G37 Base Model tire pressure changes by about 2.5% for each 10°F change in atmospheric temperature. Adjust tire pressure accordingly.
  • Underinflated tires can significantly reduce the life of 2012 Infiniti G37 Base Model tires and reduce fuel efficiency by up to 5%.
  • Overinflating 2012 Infiniti G37 Base Model tires does not increase their load-carrying capacity. Always use tire inflation value recommended for your vehicle by manufacturer.
  • When replacing original equipment tires for 2012 Infiniti G37 Base Model with plus size tires, or tires with different size, check tire load inflation chart to find proper tire pressure for your new tires.
