Fuel Saving Tips
Those drivers who set their air pressure to the higher end of the suggested range to improve fuel economy need to be especially vigilant to the rising spring temperatures. If your car recommends 32-38psi, you may choose to set your tires to 38psi for the best fuel economy. If you hit a warm day, your tires may read 42psi or more just because of the warmer temps have expanded the air in the tires. Now might be a good time to bring the pressures back to nominal to prevent over-inflation once it gets toward summer.
