Why Proper Tire Pressure Matters
Maintaining the correct tire pressure is crucial for your safety, your vehicle's performance, and your wallet. Under-inflated or over-inflated tires can lead to such issues as poor handling, reduced fuel efficiency, uneven tire wear, and even blowouts. The U.S. Department of Energy estimates that properly inflated tires can improve gas mileage by around 0.6% on average, and up to 3% in some cases (source).
Finding Your Car’s Recommended PSI
The correct tire pressure for your vehicle is specified by the manufacturer and can usually be found in one of two places:
- In your vehicle’s owner’s manual.
- On a sticker inside the driver’s door jamb.
Do not rely on the maximum PSI printed on the tire sidewall—this is the maximum pressure the tire can hold, not the recommended pressure for optimal performance.
How Often Should You Check Tire Pressure?
Tire pressure can fluctuate due to temperature changes, so it’s best to check it at least once a month and before long trips. The ideal time to check is when the tires are cold—meaning the car has been parked for at least three hours or driven less than a mile.
Using a reliable tire pressure gauge (manual or digital), remove the valve cap and press the gauge firmly onto the valve stem. A hissing sound is normal.
Make sure to check all four tires, including the spare if you have one.
How to Inflate Your Tires to the Right PSI
If the pressure is low, use an air compressor (available at most gas stations) to inflate the tires to the recommended PSI. Add air in short bursts and recheck the pressure frequently to avoid over-inflating.
If you overinflate a tire, simply release a small amount of air by pressing the center pin in the valve stem with the gauge.
Additional Tire Care Tips
Beyond checking PSI, proper tire maintenance includes:
- Rotating tires every 5,000 to 7,000 miles.
- Checking tread depth regularly.
- Ensuring proper wheel alignment.
- Inspecting for uneven wear or damage.
Neglecting tire care can lead to costly repairs and compromises safety. By following these simple steps, you’ll keep your tires in top condition, extend their lifespan, and save money on fuel and replacements.
