How to check tire pressure properly?

Checking tire pressure properly is essential for vehicle safety, fuel efficiency, and tire longevity. Here’s a step-by-step guide to help you measure and maintain the correct tire pressure: 1. **Know the Recommended Pressure:** First, find the manufacturer’s recommended tire pressure for your vehicle. This information is usually located on a sticker inside the driver’s door jamb, in the owner’s manual, or sometimes inside the fuel door. The recommended pressure is given in pounds per square inch (PSI). 2. **Use a Reliable Tire Pressure Gauge:** You can use a digital or analog tire pressure gauge. Digital gauges tend to be more accurate and easier to read. Avoid relying on the tire’s built-in pressure monitoring system (TPMS) alone, as it may not provide exact PSI values. 3. **Check When Tires Are Cold:** Measure tire pressure when the tires are cold, ideally before driving or at least three hours after driving. Driving heats up the tires, increasing air pressure and giving a false high reading. 4. **Measure Each Tire:** Remove the valve cap from the tire, press the gauge firmly onto the valve stem, and take the reading. Write down or remember the pressure. Repeat for all four tires (and the spare if applicable). 5. **Adjust the Pressure:** If the pressure is too low, add air using an air compressor until it reaches the recommended level. If it’s too high, press the valve stem core to release air and recheck. Replace the valve caps securely afterwards. 6. **Regular Checks:** Check your tire pressure at least once a month and before long trips. Properly inflated tires improve handling, safety, and fuel economy. By following these steps, you can ensure your tires are maintained at the proper pressure, contributing to safer and more efficient driving.
