Why Tire Pressure Matters

Understanding how inflation affects your tires helps you stay safe and save money over the long run.

Low Pressure Effects

  • Increased fuel consumption
  • Uneven wear on tire edges
  • Reduced handling and responsiveness
  • Higher risk of tire blowout

Correct Pressure Benefits

  • Optimal fuel economy
  • Even tread wear across the surface
  • Best handling and braking
  • Maximum tire lifespan

Over-Inflation Effects

  • Harsh and uncomfortable ride
  • Excessive center tread wear
  • Reduced traction and grip
  • Increased risk of impact damage

Sedan 32 – 35 2.2 – 2.4 30 – 33 2.1 – 2.3
SUV 33 – 36 2.3 – 2.5 31 – 34 2.1 – 2.3
Minivan 33 – 36 2.3 – 2.5 33 – 36 2.3 – 2.5
Pickup Truck 35 – 38 2.4 – 2.6 38 – 42 2.6 – 2.9
Sports Car 33 – 36 2.3 – 2.5 33 – 36 2.3 – 2.5

Tire Pressure Tips

Follow these best practices to keep your tires performing at their best all year round.

1

Check when cold. Measure tire pressure when tires are cold — meaning the car has not been driven for at least 3 hours. Driving heats the air inside and gives a falsely high reading.

2

Don't forget the spare. Your spare tire loses pressure over time just like the rest. An under-inflated spare is useless in an emergency, so include it in your routine checks.

3

Check at least monthly. Tires naturally lose about 1–2 PSI per month through permeation. A monthly check keeps you ahead of slow leaks and seasonal changes.

4

Adjust for conditions. Tire pressure drops roughly 1 PSI for every 10 °F (5.5 °C) decrease in temperature. Re-check and adjust pressure when seasons change or when driving at higher altitudes.

Frequently Asked Questions

Answers to the most common tire pressure questions from drivers.

The recommended tire pressure for your car is listed on a sticker inside the driver's side door jamb and in your owner's manual. Most passenger cars call for 30–35 PSI. This calculator provides general guidelines based on vehicle type, but always defer to your manufacturer's specification for the most accurate figure.
You should check your tire pressure at least once a month and before long trips. Tires naturally lose 1–2 PSI per month. Temperature swings between seasons can cause additional fluctuations, so increase the frequency during autumn and spring transitions.
Under-inflated tires cause increased rolling resistance, which raises fuel consumption by up to 3%. They also generate excess heat, accelerate shoulder wear, reduce steering precision, and significantly increase the risk of a dangerous blowout at highway speeds.
No. The number on the tire sidewall is the maximum allowable pressure for that tire, not the recommended operating pressure. Inflating to the sidewall maximum results in a harsh ride, poor traction, and uneven center wear. Always use the pressure specified by your vehicle manufacturer.
Yes. Tire pressure changes approximately 1 PSI for every 10 °F (5.5 °C) shift in ambient temperature. In cold weather, pressure drops; in hot weather, it rises. This is why tires inflated correctly in summer may trigger a low-pressure warning on the first cold morning of autumn. Check and adjust pressure whenever there is a significant temperature change.
